Dr. Andrew A. Snelling  is perhaps one of the world's leading researchers in flood geology.He worked for anumber of years in the mining industry throughout Australia undertaking mineral exploration surveys and fieldresearch. He has also been a consultant research geologist for more than a decade to the Australian Nuclear Science and Technology Organization  and the US Nuclear Regulatory Commission  for internationallyfunded research on the geology and geochemistry of uranium ore deposits as analogues of nuclear wastedisposal sites..His primary research interests include radioisotopic methods for the dating of rocks, formation of igneous and metamorphic rocks, and ore deposits. He is one of a controlled number permitted to take rocksamples from the Grand Canyon.He was also a founding member of the RATE group !adioisotopes and the

 Age of "he #arth$. Andrew completed a %achelor of &cience degree in Applied Geology with irst Class Honours at "he (niversityof )ew &outh *ales in &ydney, and graduated a +octor of hilosophy in geology$ at "he (niversity of &ydney,for his thesis entitled A geochemical study of the Koongarra uranium deposit, Northern Territory, Australia. %etween studies and since, Andrew worked or si! years in the e!"loration and miningindustries in "asmania, )ew &outh *ales, -ictoria, *estern Australia and the )orthern "erritory variously as afield, mine and research geologist. ulltime with the Australian creation ministry from /012 to /001, he wasduring this time also called upon as a geological consultant to the 3oongarra uranium pro4ect /0125/006$.Conse7uently, he was involved in research pro4ects with various C&8!9 Commonwealth Scientiic and#ndustrial Research Organisation$, A)&"9 Australian Nuclear Science and Technology Organisation$and (niversity scientists across Australia, and with scientists from the (&A, %ritain, :apan, &weden and the#nternational Atomic Energy Agency. As a result of this research, Andrew was involved in writing scientificpapers that were published in international scientiic $ournals. Andrew has been involved in extensive

creationist research in Australia and overseas, including the formation of all types of mineral deposits,radioactivity in rocks and radioisotopic dating, and the formation of metamorphic and igneous rocks,sedimentary strata and landscape features e.g. Grand Canyon, (&A, and Ayers !ock, Australia$ within thecreation framework for earth history. As well as writing regularly and extensively in international creationistpublications, Andrew has travelled around Australia and widely overseas (&A, (3, )ew ;ealand, &outh Africa,3orea, 8ndonesia, Hong 3ong, China$ speaking in schools, churches, colleges and universities, particularly onthe overwhelming scientific evidence consistent with the Global lood and the Creation.

&hop )ow8f the Global lood really occurred,what evidence would we expect to

find "he previous article in this seriesgave an overview of the six maingeologic evidences for the lood. )owlet?s take a closer look at evidencenumber one.*ouldn?t we expect tofind rock layers all over the earth thatare filled with billions of dead animals

and plants that were rapidly buried and fossiliEed in sand, mud, and lime 9f course, and that?s exactly what we find.,arine &ossils -igh a0o/e Sea 'e/el8t is beyond dispute among geologists that on every continent we find fossils of sea creatures in rock layers which today arehigh above sea level. or example, we find marine fossils in most of the rock layers in Grand Canyon. "his includes the

topmost layer in the se7uence, the 3aibab imestone exposed at the rimof the canyon, which today is approximately B,51, feet 6,/256,>> m$ above sea level./"hough at the top of the se7uence, this

limestone must have been deposited beneath ocean waters loaded withlime sediment that swept over northern AriEona and beyond$.9ther rocklayers exposed in Grand Canyon also contain large numbers of marinefossils. "he best example is the !edwall imestone, which commonlycontains fossil brachiopods a clamlike organism$, corals, bryoEoanslace corals$, crinoids sea lilies$, bivalves types of clams$, gastropodsmarine snails$, trilobites, cephalopods, and even fish teeth.6"hesemarine fossils are found haphaEardly preserved in this limestone bed."he crinoids, for example, are found with their columnals disks$ totallyseparated from one another, while in life they are stacked on top of oneanother to make up their Lstems.M "hus, these marine creatures werecatastrophically destroyed and buried in this lime sediment.ossilammonites coiled marine cephalopods$ like this one are found inlimestone beds high in the Himalayas of )epal. How did marine fossilsget thousands of feet above sea levelFarine fossils are also found high

in the Himalayas, the world?s tallest mountain range, reaching up to60,60 feet 1,1>1 m$ above sea level.2 or example, fossil ammonitescoiled marine cephalopods$ are found in limestone beds in the

Himalayas of )epal. All geologists agree that ocean waters must have buried these marine fossils in these limestone beds.&o how did these marine limestone beds get high up in the Himalayas*e must remember that the rock layers in theHimalayas and other mountain ranges around the globe were deposited during the lood, well before these mountains wereformed. 8n fact, many of these mountain ranges were pushed up by earth movements to their present high elevations at theend of the lood.

The E!"lanation"here is only one possible explanation for this phenomenonDthe ocean waters at some time in the past flooded over thecontinents.Could the continents have then sunk below today?s sea level, so that the ocean waters flooded over them)oO "he continents are made up of lighter rocks that are less dense than the rocks on the ocean floor and rocks in the

mantle beneath the continents. "he continents, in fact, have an automatic tendency to rise, and thus LfloatM on the mantlerocks beneath, well above the ocean floor rocks.> "his explains why the continents today have such high elevationscompared to the deep ocean floor, and why the ocean basins can hold so much water.&o there must be another way toexplain how the oceans covered the continents. "he sea level had to rise, so that the ocean waters then flooded up ontoDand overDthe continents. *hat would have caused that to happenThere had to 0e1 in act1 two mechanisms.irst, if water were added to the ocean, then the sea level would rise.&cientists are currently monitoring the melting of the polar ice caps because the extra water would cause the sea level torise and flood coastal communities. "he creation model suggests a source of the extra water."he earth?s crust was splitopen all around the globe and water apparently burst forth as fountains from inside the earth and these fountains were openfor /@ days. )o wonder the ocean volume increased so much that the ocean waters flooded over the continents.&econd, if the ocean floor itself rose, it would then have effectively LpushedM up the sea level.Genesis suggests a source of this rising sea floorK molten rock."he catastrophic breakup of the earth?s crust, , would not only have released huge volumes of water from inside the earth,but much molten rock.@ "he ocean floors would have been effectively replaced by hot lavas. %eing less dense than theoriginal ocean floors, these hot lavas would have had an expanded thickness, so the new ocean floors would haveeffectively risen, raising the sea level by more than 2,@ feet /,JB m$. %ecause today?s mountains had not yet formed,and it is likely the prelood hills and mountains were nowhere near as high as today?s mountains, a sea level rise of over 2,@ feet would have been sufficient to inundate the prelood continental land surfaces."oward the end of the lood, whenthe molten rock cooled and the ocean floors sank, the sea level would have fallen and the waters would have drained off thecontinents into new, deeper ocean basins. As indicated earlier the mountains being raised at the end of the lood and the

rock layers all over the earth filled with billions of dead animals and plants that were rapidly buried and fossiliEed in sand,mud, and lime. And that?s exactly what we find.Ra"idly De"osited Sediment 'ayers S"read Across (ast Areas9n every continent are found layers of sedimentary rocks over vast areas. Fany of these sediment layers can be traced allthe way across continents, and even between continents. urthermore, when geologists look closely at these rocks, theyfind evidence that the sediments were deposited rapidly.Consider the sedimentary rock layers exposed in the walls of theGrand Canyon in northern AriEona igure 6$. "his se7uence of layers is not uni7ue to that region of the (&A. or more than@ years geologists have recogniEed that these strata belong to six megase7uences very thick, distinctive se7uences of sedimentary rock layers$ that can be traced right across )orth America./"he lowermost sedimentary layers in GrandCanyon are the "apeats &andstone, belonging to the &auk Fegase7uence. 8t and its e7uivalents those layers comprised of the same materials$ cover much of the (&A igure 2$. *e can hardly imagine what forces were necessary to deposit sucha vast, continent wide series of deposits.

We find layers of thick sandstone around theearth. Where did the sand come from?Evidence indicates it was carried acrossentire continents by water circling the globe.Genesis 7  says that all the high hills and themountains were covered by water, and all airbreathing life on the land was swept awayand perished. After reading this passage,wouldn?t we expect to find rock layers all over the earth filled with billions of dead animals

and plants that were rapidly buried and fossiliEed in sand, mud, and lime Ies, and that?s exactly what we find.Sediment Trans"orted 'ong Distances8n previous articles we have already seen the evidence that rapidly deposited sediment layers containing rapidly buried plant

and animal fossils are found spread across vast areas, often high above sea level. )o known slowandgradual geologicprocesses in the present world are currently producing such fossiliferous sediment layers spread across continents. "houghevolutionary geologists are loath to admit it, only a global flood in which the ocean waters flooded over the continents couldhave done this.)ow it logically follows that, when the lood waters swept over the continents and rapidly depositedsediment layers across vast areas, these sediments had to have been transported long distances. 8n other words, thesediments in the strata had to come from distant sources. And that?s exactly the evidence we find.or example, in theprevious issue we discussed the Coconino &andstone, seen spectacularly in the walls of the Grand Canyon igure /$. 8thas an average thickness of 2/@ feet 0J m$, covers an area of at least 6, s7uare miles @/1, km 6$, and thuscontains at least /, cubic miles >/,B km2$ of sand./ *here did this sand come from, and how do we know"he sandgrains are pure 7uartE a natural glass mineral$, which is why the Coconino &andstone is such a distinctive buff color.+irectly underneath it is the strikingly different redbrown Hermit ormation, consisting of siltstone and shale. &and for theCoconino &andstone could not have come from the underlying Hermit ormation.

come from far awayDthe sandstone beds within the &upai Group strata between the Hermit ormation and the !edwallimestone. 8n this case, the sand LwaveM remnants point to the southeast, so the sand grains had to have been deposited bywater flowing from a source in the north and west. However, to the north and west of Grand Canyon we find only !edwallimestone underneath the &upai Group, so there is no nearby source of 7uartE sand for these sandstone beds. 2 "hus anincredibly long distance must be postulated for the source of &upai Group sand grains .>Other Sediment E/en Trans"orted Across the Continent

"he same beds of chalk are also found along the coast of rance on the other side of the #nglishChannel. "he chalk beds extend inland across #ngland and northern rance, being found as far north and west as the

 Antrim Coast and ad4oining areas of )orthern 8reland. #xtensive chalk beds are also found in )orth America, through Alabama, Fississippi and "ennessee the &elma Chalk$, in )ebraska and ad4oining states the )iobrara Chalk$, and in3ansas the ort Hayes Chalk$./"he atin word for chalk is creta. "hose familiar with the geological column and its

evolutionary timescale will recogniEe this as the name for one of its periodsDthe Cretaceous. %ecause most geologistsbelieve in the geological evolution of the earth?s strata and features over millions of years, they have linked all thesescattered chalk beds across the world into this socalled Nchalk age?, that is, a supposedly great period of millions of years of chalk bed formation.So 2hat #s Chalk5orous, relatively soft, finetextured and somewhat friable, chalk normally is white and consists almost wholly of calciumcarbonate as the common mineral calcite. 8t is thus a type of limestone, and a very pure one at that. "he calcium carbonatecontent of rench chalk varies between 0 and 01W, and the 3ansas chalk is 11501W calcium carbonate average0>W$.6 (nder the microscope, chalk consists of the tiny shells called tests$ of countless billions of microorganismscomposed of clear calcite set in a structureless matrix of finegrained calcium carbonate microcrystalline calcite$. "he twoma4or microorganisms whose remains are thus fossilised in chalk are foraminifera and the spikes and cells of calcareousalgX known as coccoliths and rhabdoliths.How then does chalk form Fost geologists believe that Nthe present is the key tothe past? and so look to see where such microorganisms live today, and how and where their remains accumulate. "heforaminifera found fossilised in chalk are of a type called the planktonic foraminifera, because they live floating in the upper 

/56 metres of the open seas. "he brown algX that produce tiny washershaped coccoliths are known ascoccolithophores, and these also float in the upper section of the open seas."he oceans today cover almost B/W of theearth?s surface. About 6W of the oceans lie over the shallower continental margins, while the rest covers the deeper oceanfloor, which is blanketed by a variety of sediments. Amongst these are what are known as ooEes, socalled because more

than 2W of the sediment consists of the shells of microorganisms such as foraminifera andcoccolithophores.2 8ndeed, about half of the deep oceanfloor is covered by lightcoloured calcareous calciumcarbonaterich$ ooEe generally down to depths of >,@5@, metres. %elow these depths the calciumcarbonate shells are dissolved. #ven so, this still meansthat about one 7uarter of the surface of the earth iscovered by these shell D rich deposits produced bythese microscopic plants and animals living near thesurface of the ocean.Geologists believe that theseooEes form as a result of these microorganisms dying,with the calcium carbonate shells and coccoliths fallingslowly down to accumulate on the ocean floor. 8t hasbeen estimated that a large /@ micron ./@mm or .J inch$ wide shell of a foraminifer may take as longas / days to sink to the bottom of the ocean, whereas

"hese differences in thicknesses of course reflect differences in accumulation rates, owing to variations inthe sediments brought in by rivers and airborne dust, and the production of organic debris within the ocean surface waters."he latter is in turn affected by factors such as productivity rates for the microorganisms in 7uestion, the nutrient supply andthe ocean water concentrations of calcium carbonate. )evertheless, it is on the deep ocean floor, well away from land, thatthe purest calcareous ooEe has accumulated which would be regarded as the presentday forerunner to a chalk bed, andreported accumulation rates there range from /51cm per /, years for calcareous ooEe dominated by foraminifera and 65/ cm per /, years for ooEes dominated by coccoliths. @)ow the chalk beds of southern #ngland are estimated to bearound >@ metres about /,260 feet$ thick and are said to span the complete duration of the socalled ate Cretaceousgeological period,J estimated by evolutionists to account for between 2 and 2@ million years of evolutionary time.

 As helpful as they are, these calculations overlook one ma4or relevant issue D these chalk beds were de"osited duringthe &lood. Creationist geologists may have different views as to where the preloodSlood boundary is in the geologicalrecord, but the ma4ority would regard these (pper Cretaceous chalks as having been deposited very late in the lood. "hatbeing the case, the coccoliths and foraminiferal shells that are now in the chalk beds would have to have been produced

during the lood itself, not in the /,J5/,B years of the prelood era as calculated by *oodmorappe, for surely if therewere that many around at the outset of the lood these chalk beds should have been deposited sooner rather than later during the lood event. &imilarly, !oth?s calculations of the re7uired 7uantities potentially being produced in up to /,years may well show that the 7uantities of calcareous ooEes on today?s ocean floors are easily producible in the timespansince the lood, but these calculations are insufficient to show how these chalk beds could be produced during the looditself.)evertheless, both *oodmorappe and !oth recogniEe that even today coccolith accumulation is not steadystate buthighly episodic, for under the right conditions significant increases in the concentrations of these marine microorganisms canoccur, as in plankton Nblooms? and red tides. or example, there are intense blooms of coccoliths that cause Nwhite water?situations because of the coccolith concentrations,// and during bloom periods in the waters near :amaica microorganismnumbers have been reported as increasing from /, per litre to / million per litre of ocean water. /1 "he reasons for these blooms are poorly understood, but suggestions include turbulence of the sea, wind, /0 decaying fish,6 nutrients fromfreshwater inflow and upwelling, and temperature.6/*ithout a doubt, all of these stated conditions would have beengenerated during the catastrophic global upheaval of the lood, and thus rapid production of carbonate skeletons byforaminifera and coccolithophores would be possible. "hermodynamic considerations would definitely not prevent a much

larger biomass such as this being produced, since &chadewald who raised this as a Nproblem? is clearly wrong. 8t has beenreported that oceanic productivity @5/ times greater than the present could be supported by the available sunlight, and it isnutrient availability especially nitrogen$ that is the limiting factor. 66 urthermore, present levels of solar ultraviolet radiationinhibit marine planktonic productivity.62Puite clearly, under cataclysmic lood conditions, including torrential rain, seaturbulence, decaying fish and other organic matter, and the violent volcanic eruptions associated with the Nfountains of thedeep?, explosive blooms on a large and repetitive scale in the oceans are realistically conceivable, so that the production of the necessary 7uantities of calcareous ooEe to produce the chalk beds in the geological record in a short space of time atthe close of the lood is also realistically conceivable. -iolent volcanic eruptions would have produced copious 7uantities of dust and steam, and the possible different mix of gases than in the present atmosphere could have reduced ultravioletradiation levels. However, in the closing stages of the lood the clearing and settling of this debris would have allowedincreasing levels of sunlight to penetrate to the oceans.9cean water temperatures would have been higher at the close of the lood because of the heat released during the cataclysm, for example, from volcanic and magmatic activity, and thelatent heat from condensation of water. &uch higher temperatures have been verified by evolutionists from their own studiesof these rocks and deepsea sediments,6> and would have also been conducive to these explosive blooms of foraminiferaand coccolithophores. urthermore, the same volcanic activity would have potentially released copious 7uantities of 

nutrients into the ocean waters, as well as prodigious amounts of the C9 6 that is so necessary for the production of thecalcium carbonate by these microorganisms. #ven today the volcanic output of C96 has been estimated at about J.J milliontonnes per year, while calculations based on past eruptions and the most recent volcanic deposits in the rock record suggestas much as a staggering >> billion tonnes of C9 6 have been added to the atmosphere and oceans in the recent past that is,in the most recent part of the postlood era$.6@

The &inal Answer "he situation has been known where pollution in coastal areas has contributed to the explosive multiplication of microorganisms in the ocean waters to peak concentrations of more than / billion per litre. 6J *oodmorappe has calculatedthat in chalk there could be as many as 2 x / /2 coccoliths per cubic metre if densely packed which usually isn?t the case$,yet in the known bloom 4ust mentioned, / billion microorganisms per litre of ocean water e7uates to //2 microorganismsper cubic metre.Adapting some of *oodmorappe?s calculations, if the /W of the earth?s surface that now contains chalkbeds was covered in water, as it still was near the end of the lood, and if that water explosively bloomed withcoccolithophores and foraminifera with up to //2 microorganisms per cubic metre of water down to a depth of less than @metres from the surface, then it would have only taken two or three such blooms to produce the re7uired 7uantity of 

microorganisms to be fossilised in the chalk beds. est it be argued that a concentration of //2

 microorganisms per cubicmetre would extinguish all light within a few metres of the surface, it should be noted that phytoflagellates such as these areable to feed on bacteria, that is, planktonic species are capable of heterotrophism they are Nmixotrophic?$.6B &uch bacteriawould have been in abundance, breaking down the masses of floating and submerged organic debris dead fish, plants,animals, etc.$ generated by the flood. "hus production of coccolithophores and foraminifera is not dependent on sunlight,the supply of organic material potentially supporting a dense concentration.&ince, for example, in southern #ngland thereare three main chalk beds stacked on top of one another, then this scenario of three successive, explosive, massive bloomscoincides with the rock record. Given that the turnover rate for coccoliths is up to two days, 61 then these chalk beds couldthus have been produced in as little as six days, totally conceivable within the time framework of the flood. *hat is certain, isthat the right set of conditions necessary for such blooms to occur had to have coincided in full measure to have explosivelygenerated such enormous blooms, but the evidence that it did happen is there for all to plainly see in these chalk beds in thegeological record. 8ndeed, the purity of these thick chalk beds worldwide also testifies to their catastrophic deposition fromenormous explosively generated blooms, since during protracted deposition over supposed millions of years it is strainingcredulity to expect that such purity would be maintained without contaminating events depositing other types of sediments."here are variations in consistency see  Appendix$ but not purity. "he only additional material in the chalk is fossils of macroscopic organisms such as ammonites and other molluscs, whose fossilisation also re7uires rapid burial because of their siEe see  Appendix$.)o doubt there are factors that need to be better 7uantified in such a series of calculations, but weare dealing with a cataclysmic lood, the like of which has not been experienced since for us to study its processes.However, we do have the results of its passing in the rock record to study, and it is clear that by working from what is knownto occur today, even if rare and catastrophic by today?s standards, we can realistically calculate production of these chalkbeds within the time framework and cataclysmic activity of the lood, and in so doing respond ade7uately to the ob4ectionsand Nproblems? raised by the critics.

 Another clue is the physical content of the rocks. "here are thousands of different types of rocks, such as huge piles of certain basalt lavas that can be matched between some continents, and hundreds of ways to measure different rockcontents, including the type of fossils they contain and the radioactive decay within certain minerals. %ased on these clues,

geologists can often determine which large deposits once lay next to each other, even after they have moved thousands of miles apart.De0ris De"ositserhaps the most significant clue to line up the continents is the type of sedimentary rock layers that the lood initiallydeposited at the edges of the cratons. "hese deposits, 4ust above the LbasementM rocks, have some distinctivecharacteristics that can be lined up between continents."he basement rocks do not have multicellular fossils in them. "heyappear to be the originally created rocks, and sediment layers deposited in the prelood world. "he remnants are all thatwe have left after the lood waters shaved off the surfaces of the continents. > "he boundary between the prelood andlood rocks usually has a distinctive erosion surface, sometimes associated with huge broken fragments of rocks."he hugefragments, sometimes measuring up to twothirds of a mile across, represent places where the edge of the preloodsupercontinent collapsed at the initiation of the lood.@ Huge slabs broke off and cascaded down into deeper waters. "heinitial lood sediments then piled up on top of these debris deposits. "he same deposits can be traced along the edge of theprelood )orth American fragment.J9thers have also noticed these same debris deposits at many other places around theglobe at the same level in the strata se7uence.B "hey help define the edges of the prelood supercontinent.

"he se7uence of events and chemical reactions necessary to form opal gets 7uite complicated. %ut here is a summary.

irst, as surface water percolated deep downward through porous sandstones and faults, oxygen reacted with the pyrite inthe sedimentary layers. As a result, the water became acidic.

"his plateau rose up at the end of the lood as the last waters receded, and %ryce was eroded into itsside."he top of this plateau consists of the pink and white layers of the Claron ormation. "he pink is due to the iron andmanganese in the sediments, which reacted with oxygen. "he hoodoos were carved out of these layers."he Claron

ormation was likely among the first sediment layers deposited in the very early postlood period immediately after the lastlood waters receded. "his plateau region was rising up around the same time, creating natural dams that producedmassive lakes in the continent?s interior including the Green !iver lakes of (tah, *yoming, and Colorado$. "he waterseventually broke through the dams, surging away from the edges of the aunsaugunt lateau see figure$. / &ubse7uentlythe water draining out of the bases of the plateau would have completed the carving of the cliffs and amphitheaters at %rycea process of headward erosion technically known as sapping$.6Conditions at the edges of these cliffs are optimal for erosion. "he layers of the Claron ormation vary in hardness, with softer mudstones alternating with harder sandstones or limestones. *hen the mudstones wash away, other rocks collapse more readily and wash away, too. "he steep slopesincrease the speed and energy of the rainwater running off the top. 8n the early years after the lood, superstorms ravagedthe earth and eroded it much faster than we see today.

 As the rain passes through the atmosphere, it becomes weakly acidic. "hat acid eats away at the sediments, especially thelimy layers. urthermore, the sedimentary layers at %ryce contain several sets of parallel cracks called 4oints. *ater entersthese cracks, where it freeEes at night and thaws during the dayDtoday the region experiences 6 freeEethaw cycles per yearDfurther weakening the rock layers.As the water flows downward, it picks up debris and scours any softer rocks it

"he gullies widen into canyons, exposing more surfaces to erosion along their vertical cracks.urther freeEethaw cycles expand the cracks and peel off side layers, especially of the softer rocks.)ormally we would expect weathered rocks to collapse into piles, rather than leaving behind tall, slender columns.

The Sierra Ne/adasConsider the landscape one step at a time. irst, where did the&ierra )evadas come from before the (shaped valley wascarved into them +uring the lood many sedimentary rock

layers were deposited right across the )orth Americancontinent, as the ocean waters rose and flooded it. ate in thelood, the moving tectonic plates shoved some of the newacific 9cean floor down under the western edge of )orth

 America. As the ocean floor sank subducted$, the heat atdepth caused the ad4acent rock above to melt, producinggranite magmas. "he compression in this collision Eones7ueeEed the granite magmas into the sediment layers above.

 At the same time, the layers were being buckled and uplifted,producing the &ierra )evadas.*hen the granite magmass7ueeEed up into the buckled sedimentary layers, they cooledand crystalliEed in large bulbous masses, about 2, feet0,/@ m$ below the surface. "hese cooling granites alsocontracted, resulting in parallel fractures at right angles to oneanother.As the lood waters retreated, catastrophic erosion

scoured the uplifting mountains. Fost of the sedimentarylayers were removed by the retreating water and exposed themore resistant bulbous granite masses. +espite all thiserosion, the uplifted &ierra )evadas still rose to over />,

feet >,6B m$ above sea level."he fractures influenced the direction of the weathering and erosion of the granite masses. Another factor was the peeling off spalling$ of sheets on the surface of the granites, often leaving behind large granitedomes. 8n the early postlood decades, heavy rainfall eroded the deep Ferced !iver -alley. "he water, which was flowingin tributaries, could not cut into the more resistant granite walls and thus tumbled over waterfalls into the valley.

 A+-#!"8&#F#)"&Faranatha %aptist (niversityensacola Christian CollegeFasters College"hree &cenariosCareful investigations of the rocks in the small mines from which emeralds are extracted have revealed three scenarios toexplain how most emeralds formed.

8n the first scenario, molten rock magma$ deep in the earth?s interior, containing beryllium and water, forced its way upwardtoward the earth?s surface and was s7ueeEed into nearsurface rocks, where it crystalliEed and cooled as granite. "he laststage of this process produced pegmatite veins, which were rich in water and often beryllium. *herever the molten graniteand pegmatite veins particularly the latter$ came into contact with black shales and other rocks rich in chromium andvanadium, the hot water mixed the three essential ingredients to form emeralds.8n Colombia there is no evidence of thesegranites or pegmatites. 8nstead, the emeralds are found within veins and fractured rocks along faults. "he process of forming these high7uality emeralds began when hot groundwaters mixed with salt beds deep in the earth, causing thewater to become highly alkaline and salty. "hen the hot water, filled with various dissolved elements like beryllium, moved upalong the faults and fractures into the shales."he third scenario took place as sedimentary rocks were crumpled ands7ueeEed by earth movements. *ater was already in these sediment layers, as the heat and pressure metamorphosed the

"his rare 4uxtaposition explains why emerald deposits occurred in so few places."hese findingshelp us to place emerald deposits within the Creationlood framework of earth history. "he global lood involved a seriesof catastrophic plate movements and collisions, each step of which would explain the different scenarios to form thesegems.J*hen the lood event began, the prelood supercontinent was torn into pieces. "he catastrophic collision of these

 4ostling crustal plates caused new mountains to rise, with the accompanying formation of the granites and metamorphicrocks associated with the creation of new emeralds.B"he first mountains built early in the lood year would have beendeeply eroded, as the subse7uent water movements scoured all previous sedimentary deposits. Any emerald deposits were

then exposed and washed into new locations.

8t can easily be demonstrated that these granitic rock units in southern 8srael were buried under thick sedimentaryse7uences during the lood. 8n the areas where these samples were obtained, the unconformity between these granitic rockunits and the overlying looddeposited sedimentary se7uence is exposed fig. /$. "hus at some stage during the lood, asor after the overlying sedimentary se7uence was deposited, the basinal brines in these deeply buried basal Cambrian$sediments 4ust above the unconformity would likely have been heated sufficiently to become hydrothermal fluids. "his hasbeen confirmed by evidence that temperatures in the overlying Cambrian sandstone reached as high as 6VC -ermeesch,

 Avigad, and Fc*illiams 60$. "hese hydrothermal fluids would then have circulated down into the underlying recambriancrystalline basement rocks. "hat this has certainly occurred in the "imna 8gneous Complex rocks has been confirmed bypaleomagnetic and isotopic evidence%eyth et al. /00BQ Farco et al. /002QFatthews et al. /000$. And since itoccurred at the end of the loodduring the early triggering stages of tectonic activity along the +ead &earift, which is ad4acent to both sampledareas, then most of the recambriangranitic and metamorphic rocks wouldhave been affected similarly.However, %eyth et al. /00B$ showedthat the monEodiorite was morealtered than the alkali granite by these circulating hydrothermal fluids. "hus it seems reasonable to conclude that the degree

of alteration corresponds to the volume of hydrothermal fluids which circulated through these rocks. "his in turn would beconsistent with the earlier proposal that the greatest abundance of radiohalos in the monEodiorite is due to a greater volumeof hydrothermal fluids circulating through it during the lood. 8f this conclusion is correct, then it would imply that the !odedorphyritic Granite in the &hehoret Canyon area, with its consistent low radiohalos abundance, had slightly morehydrothermal fluidflow through it than the "imna alkali granite with its complete lack of radiohalos.

"he availablesubsurface data from drilling suggests that this terminal recambrian ;enifim basin which formed north of the #lat area was/@56

 Arabian)ubian &hield is now exposed in the #lat area and the nearby &inai, because the grain siEe of the basin sedimentsgenerally tends to decrease northwards.Applying the five discontinuity criteria of Austin and *ise /00>$ to determine the

preloodSlood boundary in southern 8srael, there are only two possibilitiesK the unconformity at the base of the fossiliferousCambrian strata se7uence, or the unconformity between the crystalline basement and the terminal )eoproteroEoic coarseclastics with interbedded volcanics figs. // and /6$. 8n any case, these two unconformities merge at the exposed erosionsurface on the crystalline basement, which certainly represents a mechanicalerosional discontinuity. "here is only a veryshort time or age discontinuity at both unconformities, and both unconformities represent tectonic discontinuities. &o far there is no data on whether the ;enifim ormation contains any fossils, but due to it consisting of coarse immature clastics,the depositional conditions would not have been conducive for fossiliEation.-ery little data pertaining to the ;enifimormation is available apart from that obtained in boreholes, so a definitive determination is problematical. However, givensome clear similarities between the coarse, poorly sorted, polymictic conglomerates and immature lithic arkoses of the;enifim ormation and the #lat Conglomerate and volcanoconglomeratic series$ and both the &ixtymile ormation inGrand Canyon and the 3ingston eak ormation in the Fohave +esert, it is considered that on balance the ;enifimormation and the related conglomerates$ likely represent the initial lood deposits in southern 8srael. *ith the breaking upof the Lfountains of the great deepM triggering the onset of the lood, massive erosion of the crystalline basement wouldhave occurred, with submarine debris avalanches rapidly accumulating these sediments catastrophically on the flanks of the

rifting edges of the prelood supercontinent Austin et al. /00>Q Austin and *ise /00>Q &igler and *ingerden /001Q*ingerden 62$. "he presence of interbedded volcanics and contemporaneous explosive volcanism would be testimony tothe volcanic activity likely accompanying this breaking up process. "hus the preloodSlood boundary in southern 8sraelwould be the unconformity between the terminal roteroEoic ;enifim ormation and the erosion surface across thecrystalline basement. However, in some places the fossiliferous Cambrian strata se7uence sits unconformably directly onthat erosion surface across the recambrian crystalline basement.(nlike the Grand CanyonColorado lateau area wherethere is a very large radioisotope time gap between the last igneous activity the Cardenas %asalt and related diabase sillsconventionally regarded as ]/./ Ga$ and the onset of the lood event near the terminal recambrianCambrianunconformity Austin /00>Q Austin and *ise /00>Q %eus and Forales 62$, in the northernmost Arabian)ubian &hield areaof southern 8srael, repeated, almost continuous igneous activity seems to have spanned the last / million years or so of the recambrian right up to, and on into, the onset of the lood event. "he physical manifestation at the earth?s surface thatthe lood was beginning was the catastrophic Lbreaking upM of Lthe fountains of the great deepM, but the creation accountdoesn?t indicate what precursors may have been occurring inside the earth, even for years before, which triggered thatLbreaking up.M rom a geophysical perspective, igneous activity had to have built up molten rock and accompanying steaminside the earth under confining pressure until the magma and steam were cataclysmically released by the renting apart of 

the earth?s surface. "hus the rocks resulting from this igneous activity throughout the terminal recambrian in southern8srael may be the record of this precursor buildup inside the earth that eventually triggered the lood event. 8ndeed, thelatest igneous activity from about J/  Fa onwards has been described as occurring in a crustal extension or rifting tectonicregime, with the intrusion of the "imna alkali granite and monEodiorite followed by the multiple generations of dike swarms,and the initiation of catastrophic erosion and depositional of the ;enifim ormation %eyth et al. /00>aQ Garfunkel /000$.Asfor the radioisotope timescale involved, -ardiman et al. 6@$ reported five independent evidences that demonstrate a lot of nuclear decay occurred during the lood event at grossly accelerated rates. A significant biproduct of this acceleratedradioisotope decay would have been a huge amount of heat, which would have rapidly increased as the radioisotope decayexponentially accelerated. 8f this acceleration of radioisotope decay was initiated months before the lood event began onthe earth?s surface, then the heat which rapidly accumulated as a result would have begun melting upper mantle and lower crustal rocks. "he intrusive igneous rocks produced within those few months would have LagedM radioisotopically by tens of millions of years due to the accelerating nuclear decay, while the pressure confining the molten rock and steam would havebuilt up until they could not be held LinM any longer, so Lthe fountains of the great deepM were broken up. &uch an initiationprocess would thus explain the close spatial and temporal relationship between the terminal recambrian igneous activity in

the prelood crystalline basement of southern 8srael and the tectonic upheaval and catastrophic erosion and depositionwhich marked the beginning of the cataclysmic lood event.

evident from the hydrothermal alteration present especially in the 7uartE syenite bodies, and from the contact metasomaticalteration and brecciation of the sedimentary rocks immediately ad4acent to the intrusives 8tamar and %aer /002$.urthermore, polymetallic hydrothermal mineraliEation occurs as veins and lenses within phreatomagmatic breccia Eones atthe roofs of the 7uartE syenite intrusions close to their contacts with the overlying sedimentary rocks.

Generally speaking, dolomitic facies are better developed in the western :udean Hills, while limeyfacies are more abundant in the central or eastern part. %ecause of the observation that dolomites only form today in

minor marls and cherts, were deposited in very shallow water under evaporitic conditions. However, such slowandgradual

depositional conditions today do not preserve footprint impressions. )or would dinosaurs have lived in shallow salty water where there was no food to eatO Foving shallow water today will degrade the LwallsM of such impressions soon after beingmade in wet dolomitic sands and muds, and any prolonged period of exposure would obliterate them. 9n the other hand,the making of these fossiliEed dinosaur footprints can be explained under the prevailing conditions during the lood&nelling 6/b$. As already indicated, the dolomitic sands and muds would have been precipitated from hot Fgcarbonaterich hydrothermal fluids, mixing with the colder lood waters. +uring a very brief tidal drop in the water level, this theropoddinosaur that had earlier been swept away in the lood waters, in which it was then floundering$ was able to walk across arapidly and temporarily exposed or semiexposed$ surface of the dolomitic sandSmud leaving its footprints behind. "hatsurface would have been firm due to the cohesiveness of the semiwet dolomite, where a chemical reaction would start toLsetM the dolomite, 4ust as occurs today in very similar manmade cement, retaining the footprint impressions. However, thiswould have occurred in the brief timeframe before the next tidal surge raised the water level again and swept away thedinosaur, and rapidly covered the footprints with more dolomitic sediments to preserve them. "his entire se7uence had tohave occurred within hours, with its rapid burial and with hardening of the dolomite pavement completed by the weight of theoverlying layers s7ueeEing the water out of it, or else these dinosaur footprints would not have been fossiliEed. )othing like

this happens under today?s conditions. And if this shallow water evaporitic depositional environment had been proximal towhere this dinosaur supposedly lived, its bones should be found buried nearby. 9n the contrary, this dinosaur was sweptaway in the lood waters to eventually perish, any trace of its bones likely being buried far away from its footprints, andmuch higher in the rapidly deposited strata se7uence %rand and lorence /016Q &nelling 60b$.

"he dominant component of the homogeneous chert is micro andcryptocrystalline 7uartE. &ilicified fossils are beautifully exposed, ghosts of foraminiferal tests are common, andforaminiferal cavities are infilled with coarser 7uartE. "he chert is usually brown, with the centers of beds or nodules oftenbeing black due to the higher up to /.2W$ content of organic matter.

"hese included the sulfate minerals gypsum and anhydrite Ca$, and celestine &r$, as well as dolomite Fg,Ca carbonate$. 8t is thus clear that saline conditions were necessary for both the cherts and these LevaporiteM minerals to

form. However, it is incorrect to assume these minerals formed by evaporation. 8nstead, these silica, sulfate and carbonateminerals readily precipitate from saline fluids, particularly hot saline fluids Hovland et al. 6J$. "hus it can be envisagedthat these cherts and associated minerals precipitated as saline to saturated hydrothermal fluids, emanating from deepmagmas and hot basement rocks via fissures, made contact and mixed with the cooler sedimentcarrying lood waterstransgressing the continental crustal surfaces &nelling 60b$."hese same hot saline to saturated hydrothermal$ fluids arealso the key to explaining the rapid lood accumulation of the chalk beds themselves &nelling /00>, 60b$.

"here is also experimental evidence that low FgSCa ratios and high Ca concentrations in seawater,

Puite clearly, all these necessary conditions for explosive blooming of coccolithophores would have been present during the cataclysmic global upheavals of the lood. "orrential rain, seaturbulence, decaying fish and other organic matter, and the violent volcanic eruptions on the ocean floor and on landcausing steam, carbon dioxide, Ca, and other elements and salts to be spewed into the lood waters, would have resultedin explosive blooms of coccolithophores on a large and repetitive scale. urthermore, the ocean water temperatures wouldhave been higher towards the end of the lood when these Cretaceous chalk beds were deposited because of all the heatreleased by all the catastrophic, global volcanic and magmatic activity. "hus the rapid production of the necessary 7uantitiesof calcareous ooEe to form the thick chalk beds in a matter of days to weeks toward the end of the lood year is realisticallyconceivable &nelling /00>, 60b$. 8ndeed, the extreme purity of the chalk beds, usually 0W CaC9 2 etti4ohn /0@B$,argues for their rapid deposition and formation, and the chert and the associated LevaporiteM minerals$ in them are directevidence of the hot saline to saturated fluids involved.However, investigations have shown that once these Ft. &copusGroup chalk beds were deposited the biogenetic fragments were cemented together to make chalky limestone by sparrycalcite precipitated from fresh water FagaritE /0B>$.

biogenetic debris which constitutes the chalk beds accumulated as a result of the rapid production of coccolithophores inexplosive blooms in warm lood waters being in4ected with hot saline fluids from violent volcanic eruptions and magmaticactivity on a global scale. "o the contrary, this fresh water appears to have come from the a7uifer below these chalk bedssome time after deposition of the biogenetic debris. 8t is only the lower section of the chalk beds that have been lithified intochalky limestone by the introduction of sparry calcite to infill the foraminiferal tests and pores.

"hese are the

same criteria, namely, continental sediments of relatively small volume and very restricted in extent, that

 Austin et al. /00>$ used to place the loodSpostloodboundary globally at the CretaceousS"ertiary 3S"$boundary in the geologic record. &imilarly, *hitmoreand Garner 61$ listed criteria such as localsedimentary units, lacustrine and fluvial continental$deposits, and true desiccation cracks, evaporites andbioturbation as indicative of postlood sedimentaryrocks. 8t was using these and other$ criteria that the#ocene Green !iver ormation of *yoming was

Austin /001a$ also argued

for marine sediments still to be deposited on the continents in regressive se7uences as the lood waters retreated, becausehe stated thatK As the ocean retreated, nutrientrich waters allowed coccoliths to flourish as massive algal blooms contributed ooEes to theocean floor . . . so that$ marine sedimentation of chalk continued into the postlood period in 8srael."he chalksedimentation he referred to could only be the chalk beds that dominate the Ft. &copus and Avedat Groups figs. 6 and 6/$.However, these groups span the interval from the upper Cretaceous through to the upper #ocene with continuousdeposition of thick chalk beds, with some cherts and marls, and minor limestones right across 8srael fig. 6$. "hese certainlyrepresent marine sediments deposited on the continent, but their massive nature figs. 6 and 2$ and fairly uniform thicknessright across 8srael do not suggest they belong to a regressive se7uence."o the contrary, rather than placing the loodSpostlood boundary in the geologic record of 8srael at the CretaceousS"ertiary 3S"$ boundary in the middle of where there wascontinuous chalk deposition, it makes more sense to place it between the #ocene and Fiocene. At the end of the #ocenethere is a ma4or welldefined and recogniEed regression right across 8srael due to the retreating of the ocean lood$ watersoff the country Garfunkel /0B1$, followed by a period of extensive erosion in the 9ligocene Garfunkel and HorowitE /0JJ$,before the arguably postlood isolated minor continental sediments were deposited in the Fiocene fig. 6$.urthermore, theoriginally continuous AraboAfrican craton was only rifted apart in the CenoEoic to form the present plate boundaries in 8srael

and nearby countries Garfunkel /0B1$. !ifting began only in the 9ligocene in the southern !ed &ea area to begin openingit, but most of the opening of the !ed &ea was contemporaneous with the slip on the +ead &ea rift, the ma4ority of whichwas probably during the Fiocene reund, ;ak and Garfunkel /0J1$. At the same time this rifting formed the +ead &eabasin, the :ordan valley, the &ea of Galilee and the Hula basin another lakefilled depression north of Galilee$, drag andfrictional forces along the +ead &ea "ransform ault caused the thick se7uence of lood strata in central and northern8srael, including the limestone and chalk beds of the middle Cretaceous to #ocene :udea, Ft. &copus and Avedat Groups,to be arched upward to form the :udean Fountains and the ad4oining foothills to the west Austin /001a$.&ince the geologicprocesses which were occurring at catastrophic rates during the lood are still operating today at a snail?s pace for example, plate tectonics and volcanism$, it is likely that as the lood ended these geologic processes did not stop abruptly,but rapidly decelerated. "his is confirmed by the declining eruption power of postlood volcanoes Austin /001b$. "hus it islikely there were residual local catastrophes in the early postlood years that produced some sedimentary layers in localbasins and dramatically eroded some impressive landscape features. And in some places marine sediments could still havebeen deposited on continental land surfaces marginal to today?s ocean basins, because the lood waters had not then fullyretreated to today?s coastlines.8t could thus be argued from the above considerations that the loodSpostlood boundary in

the geologic record of 8srael, could still be at the CretaceousS"ertiary 3S"$ boundary within the Ft. &copus Group strata, inkeeping with the Austin et al. /00>$ positioning of the loodSpostlood boundary from a global perspective, because thelood waters had not fully retreated from off the land of 8srael. However, given that there is strong, wellrecogniEed evidenceof the ocean lood$ waters having finally retreated from off the land of 8srael to approximately the present coastlineimmediately after continuous uninterrupted$ deposition of the thick LmarineM limestone, dolomite and chalk beds of themiddle Cretaceous#ocene :udea, Ft. &copus and Avedat Groups, accompanied by subse7uent extensive erosion anddrying of the land surface, it seems more reasonable to place the loodSpostlood boundary in the geologic record of 8sraelin the 9ligocene, or at the end of it. "his placement of the boundary still re7uires some residual local geologic activity tohave rapidly occurred in 8srael tectonic ad4ustments, erosion, sedimentation and volcanic eruptions$ during the earlydecades of the postlood period before post%abel people migrated into the land ahead of Abraham?s subse7uent arrival.Conclusion"he sedimentary strata that comprise and cover most of 8srael provide an obvious record of the lood, in keeping with thegeologic evidences as outlined by Austin /00>$, &nelling 6B$, and elaborated on subse7uently for example, &nelling61a, b, c$.

of chemicalrich hot waters from associated volcanism, allowing coccoliths to flourish as massive algal blooms that thenrapidly accumulated as ooEes to become thick chalk beds. "hese were not 4ust a local phenomenon, as these chalk beds in8srael can be traced west across #urope to #ngland and 8reland, and east to 3aEakhstan, with other remnants in theFidwest of the (&A and in southern *estern Australia. %oth these examples powerfully illustrate the global lood depositionof transcontinental rock layers &nelling 61c$."he formation of mountains would have re7uired powerful tectonic upheavalprocesses that overturned and upthrusted sedimentary strata. &imultaneous isostatic ad4ustments would also have resultedin restoring the continental land surfaces as the lood waters drained off into new deep ocean basins. 8n 8srael this greatregression, as the lood waters receded and widespread marine sedimentation ended, also coincided with thecommencement of the rifting that opened up the !ed &ea and the +ead &ea:ordan !iver rift valley along the +ead &ea"ransform ault, as well as the uplifting of the :udean Fountains along a northsouth axis of folding the :udean Arch$, andthe thrust faulting that created 8srael?s highest peak, Ft.

the sandstone fabric would have become weakened and then collapsed, as the clays and remaining unbound mineral grainswould have easily disintegrated and been entirely washed away, leaving no (luru at allOurthermore, sand grains which aremoved over long distances and periodically swept further and further over vast eons of time would lose their 4agged edges,becoming smooth and rounded. At the same time, the same sand grains being acted upon by the moving water over thoseclaimed long periods of time should also be sortedQ the smaller grains are carried more easily by water, so would beseparated from the larger grains. "hus if the (luru Arkose had taken millions of years to accumulate as evolutionarygeologists claim, then the rock today should have layers of either small or large grains. &o fresh, shiny feldspar crystals and

And this traumatic event had to be recent, otherwise the feldspar crystals in the arkose would not be asfresh unweathered$ as they are today.

"he (luru Arkose as seen under a geological microscope. )ote the mixtures of grainsiEes and the 4agged edges of the grains.  &ince the layers of arkose andconglomerate are now tilted, the arkose almost vertically, it is also obvious that after

landscape began to dry out. "he chemicals in the water still trapped between grains of sand, pebbles, boulders, etc.continued to form a binding and hardening material similar to cement in concrete.Conclusion"he evidence overall does not  fit the story of evolutionary geologists, with its millions of years of slowandgradualprocesses. 8nstead, the evidence in the rock layers at (luru and 3ata "4uta is much more consistent with the scientific modelbased on a recent, rapid, massive, catastrophic flood. (luru and 3ata "4uta are therefore stark testimony to the ragingwaters of the global lood.

Aneasily noticed feature of the Coconino &andstone is the distinct cross layers of sandwithin it called cross beds see igure 2, right$. or many years evolutionarygeologists have interpreted these cross beds by comparing them with currentlyforming sand deposits D the sand dunes in deserts which are dominated by sandgrains made up of the mineral 7uartE, and which have inclined internal sand beds.

"hus it has been proposed that the Coconino &andstone accumulated over thousands and thousands of years in an immense windy desert by migrating sanddunes, the cross beds forming on the downwind sides of the dunes as sand wasdeposited there.2

glance this interpretation would appear to be an embarrassment to creation geologists who are unanimous in their belief thatit must have been a Global lood that deposited the flat lying beds of what were once sand, mud and lime, but are nowexposed as the rock layers in the walls of the Canyon.Above the Coconino &andstone is the "oroweap ormation and belowis the Hermit ormation, both of which geologists agree are made up of sediments that were either deposited by andSor inwater. @,J How could there have been a period of dry desert conditions in the middle of the lood year when N all the high hillsunder the whole heaven were covered? by water"his seeming problem has certainly not been lost on those, even fromwithin the Christian community, opposed to lood geologists and creationists in general. or example, +r +avis Ioung,rofessor of Geology at Calvin College in Grand !apids, Fichigan, in a recent book being marketed in Christian bookshops,has merely echoed the interpretations made by evolutionary geologists of the characteristics of the Coconino &andstone,arguing against the lood as being the agent for depositing the Coconino &andstone. He is most definite in his considerationof the desert dune modelKN"he Coconino &andstone contains spectacular cross bedding, vertebrate track fossils, and pitted and frosted sand grain

surfaces. All these features are consistent with formation of the Coconino as desert sand dunes. "he sandstone iscomposed almost entirely of 7uartE grains, and pure 7uartE sand does not form in floods = no flood of any siEe could haveproduced such deposits of sand =?BThose oot"rints"he footprint trackways in the Coconino &andstone have recently been reexamined in the light of experimental studies by+r eonard %rand of oma inda (niversity in California.1 His research program involved careful surveying and detailedmeasurements of 16 fossiliEed vertebrate trackways discovered in the Coconino &andstone along the Hermit "rail in GrandCanyon. He then observed and measured 62J experimental trackways made by living amphibians and reptiles inexperimental chambers. "hese tracks were formed on sand beneath the water, on moist sand at the water?s edge, and ondry sand, the sand mostly sloping at an angle of 6@ degrees, although some observations were made on slopes of /@degQand 6V for comparison. 9bservations were also made of the underwater locomotion of five species of salamandersamphibians$ both in the laboratory and in their natural habitat, and measurements were again taken of their trackways.Adetailed statistical analysis of these data led to the conclusion, with a high degree of probability that the fossil tracks musthave been made underwater. *hereas the experimental animals produce footprints under all test conditions, both up and

down the 6@V slopes of the laboratory Ndunes?, all but one of the fossil trackways could only have been made by the animalsin 7uestion climbing uphill. "oe imprints were generally distinct, whereas the prints of the soles were indistinct. "hese andother details were present in over 1W of the fossil, underwater and wet sand tracks, but less than /6W of the dry sand anddamp sand tracks had any toe marks. +ry sand uphill tracks were usually 4ust depressions, with no details. *et sand trackswere 7uite different from the fossil tracks in certain features. Added to this, the observations of the locomotive behaviour of the living salamanders indicated that all spent the ma4ority of their locomotion time walking on the bottom, underwater, rather than swimming.utting together all of his observations, +r %rand thus came to the conclusion that the configurations andcharacteristics of the animals trackways made on the submerged sand surfaces most closely resembled the fossiliEed7uadruped trackways of the Coconino &andstone. 8ndeed, when the locomotion behaviour of the living amphibians is takeninto account, the fossiliEed trackways can be interpreted as implying that the animals must have been entirely under water not swimming at the surface$ and moving upslope against the current$ in an attempt to get out of the water. "hisinterpretation fits with the concept of a global lood, which overwhelmed even fourfooted reptiles and amphibians thatnormally spend most of their time in the water.)ot content with these initial studies, +r %rand has continued with the help of a colleague$ to pursue this line of research.He recently published further results,0 which were so significant that a brief report of their work appeared in cience

>ews/ and Geology 3oday . //His careful analysis of the fossiliEed trackways in the Coconino &andstone, this time not only from the Hermit "rail in GrandCanyon but from other trails and locations, again revealed that all but one had to have been made by animals moving upcross bed slopes. urthermore, these tracks often show that the animals were moving in one direction while their feet werepointing in a different direction. 8t would appear that the animals were walking in a current of water, not air. 9ther trackwaysstart or stop abruptly, with no sign that the animals? missing tracks were covered by some disturbance such as shiftingsediments. 8t appears that these animals simply swam away from the sediment.%ecause many of the tracks havecharacteristics that are N4ust about impossible? to explain unless the animals were moving underwater, +r %rand suggestedthat newtlike animals made the tracks while walking under water and being pushed by a current. "o test his ideas, he andhis colleague videotaped living newts walking through a laboratory tank with running water. All 621 trackways made by thenewts had features similar to the fossiliEed trackways in the Coconino &andstone, and their videotaped behaviour whilemaking the trackways thus indicated how the animals that made the fossiliEed trackways might have been moving."heseadditional studies confirmed the conclusions of his earlier researches. "hus, +r %rand concluded that all his data suggestthat the Coconino &andstone fossil tracks should not be used as evidence for desert wind deposition of dry sand to form the

Coconino &andstone, but rather point to underwater deposition. "hese evidence from such careful experimental studies by alood geologist overturn the original interpretation by evolutionists of these Coconino &andstone fossil footprints, and thuscall into 7uestion their use by Ioung and others as an argument against the lood.Desert 6dunes35"he desert sand dune model for the origin of the Coconino &andstone has also recently been challenged by Glen -isher /6,rofessor of Geology at the (niversity of "ulsa in 9klahoma, and not a creationist geologist. -isher noted that large storms,or amplified tides, today produce submarine sand dunes called Nsand waves?. "hese modern sand waves on the sea floor contain large cross beds composed of sand with very high 7uartE purity. -isher has thus interpreted the Coconino&andstone as a submarine sand wave deposit accumulated by water, not wind. "his of course is directly contrary to Ioung?sclaims, which after all are 4ust the repeated opinions of other evolutionary geologists.urthermore, there is other evidencethat casts grave doubts on the view that the Coconino &andstone cross beds formed in desert dunes. "he average angle of slope of the Coconino cross beds is about 6@V from the horiEontal, less than the average angle of slope of sand beds withinmost modern desert sand dunes. "hose sand beds slope at an angle of more than 6@V, with some beds inclined as much as2V to 2>V, the angle of Nrest? of dry sand. 9n the other hand, modern oceanic sand waves do not have Navalanche? faces of sand as common as desert dunes, and therefore, have lower average dips of cross beds.-isher also points to other positiveevidence for accumulation of the Coconino &andstone in water. *ithin the Coconino &andstone is a feature knowntechnically as Nparting lineation?, which is known to be commonly formed on sand surfaces during brief erosional burstsbeneath fastflowing water. 8t is not known from any desert sand dunes. "hus -isher also uses this feature as evidence of vigorous water currents accumulating the sand, which forms the Coconino &andstone.&imilarly, -isher has noted that thedifferent grain siEes of sand within any sandstone are a reflection of the process that deposited the sand. Conse7uently, heperformed sand grain siEe analyses of the Coconino &andstone and modern sand waves, and found that the Coconino&andstone does not compare as favourably to dune sands from modern deserts.

He found that not only is the pitting not diagnostic of the last rocess to have deposited the sand grains pitting can, for example, form first by wind impacts, followed by redeposition by water$, but pitting and frosting of sand grains can formoutside a desert environment./2 or example, geologists have described how pitting on the surface of sand grains can formby chemical processes during the cementation of sand.&and wave deposition

igure @. &chematic diagram showing the formation of cross beds during sand deposition by migration of underwater sandwaves due to sustained water flow.A considerable body of evidence is now available which indicates that the Coconino&andstone was deposited by the ocean, and not by desert accumulation of sand dunes as emphatically maintained by most

evolutionary geologists, including Christians like +avis Ioung. "he cross beds within the Coconino &andstone that is, theinclined beds of sand within the overall horiEontal layer of sandstone$ are excellent evidence that ocean currents moved thesand rapidly as dunelike mounds called sand waves. igure @ right$ shows the way sand waves have been observed toproduce cross beds in layers of sand. "he water current moves over the sand surface building up mounds of sand. "hecurrent erodes sand from the Nupcurrent? side of the sand wave and deposits it as inclined layers on the Ndowncurrent? sideof the sand wave. "hus the sand wave moves in the direction of current flow as the inclined strata continue to be depositedon the downcurrent side of the sand wave. Continued erosion of sand by the current removes both the upcurrent side andtop of the sand wave, the only part usually preserved being 4ust the lower half of the downcurrent side. "hus the height of the cross beds preserved is 4ust a fraction of the original sand wave height. Continued transportation of further sand willresult in repeated layers containing inclined cross beds. "hese will be stacked up on each other.&and waves have beenobserved on certain parts of the ocean floor and in rivers, and have been produced in laboratory studies. Conse7uently, ithas been demonstrated that the sand wave height is related to the water depth./@  As the water depth increases so does theheight of the sand waves which are produced. "he heights of the sand waves are approximately onefifth of the water depth.&imilarly, the velocities of the water currents that produce sand waves have been determined."hus we have the means to

calculate both the depth and velocity of the water responsible for transporting as sand waves the sand that now makes upthe cross beds of the Coconino &andstone. "he thickest sets of cross beds in the Coconino &andstone so far reported are2 feet 0 metres$ thick./J Cross beds of that height imply sand waves at least J feet /1 metres$ high and a water depth of around 2 feet between 0 and 0@ metres$. or water that deep to make and move sand waves as high as J feet /1metres$ the minimum current velocity would need to be over 2 feet per second 0@ centimetres per second$ or 6 miles per hour. "he maximum current velocity would have been almost @.@ feet per second /J@ cm or /.J@ metres per second$ or 2.B@ miles per hour. %eyond that velocity experimental and observational evidence has shown that flat sand beds only wouldbe formed.)ow to have transported in such deep water the volume of sand that now makes up the Coconino &andstonethese current velocities would have to have been sustained in the one direction perhaps for days. Fodern tides and normalocean currents do not have these velocities in the open ocean, although deepsea currents have been reported to attainvelocities of between @ cm and 6@ cm 6.@ metres$ per second through geographical restrictions. "hus catastrophicevents provide the only mechanism, which can produce high velocity ocean currents over a wide area.Hurricanes or cyclones in the southern hemisphere$ are thought to make modern sand waves of smaller siEe than those that haveproduced the cross beds in the Coconino &andstone, but no measurements of hurricane driven currents approaching thesevelocities in deep water have been reported. "he most severe modern ocean currents known have been generated during atsunami or Ntidal wave?. 8n shallow oceans tsunamiinduced currents have been reported on occasion to exceed @ cm @metres$ per second, and currents moving in the one direction have been sustained for hours. /B &uch an event would beable to move large 7uantities of sand and, in its waning stages, build huge sand waves in deep water. Conse7uently, atsunami provides the best modern analogy for understanding how largescale cross beds such as those in the Coconino&andstone could form.*o0al &lood5*e can thus imagine how the lood would deposit the Coconino &andstone and its e7uivalents$, which covers an area of 6, s7uare miles @/1, s7uare kilometres$ averages 2/@ feet 0J metres$ thick, and contains a volume of sandconservatively estimated at /, cubic miles >/,B cubic kilometres$. %ut where could such an enormous 7uantity of sand come from Cross beds within the Coconino dip consistently toward the south, indicating that the sand came from thenorth. However, along its northern occurrence, the Coconino rests directly on the Hermit ormation, which consists of siltstone and shale and so would not have been an ample source of sand of the type now found in the Coconino &andstone.Conse7uently, this enormous volume of sand would have to have been transported a considerable distance, perhaps atleast 6 or 2 miles 26 or >1 kilometres$. At the current velocities envisaged sand could be transported that distance in

a matter of a few daysO"hus the evidence within the Coconino &andstone does not support the evolutionary geologistsinterpretation of slow and gradual deposition of sand in a desert environment with dunes being climbed by wandering fourfooted vertebrates. 9n the contrary, a careful examination of the evidence, backed up by experiments and observations of processes operating today indicates catastrophic deposition of the sand by deep fastmoving water in a matter of days,totally consistent with conditions envisaged during the lood.

ithospheric plates at the surface, whichinclude the crust and part of the upper mantle, move laterally over theasthenosphere. "he asthenosphere ishot and also weak because of thepresence of water within its constituentminerals. 9ceanic lithosphere, whichlacks the continental crust, is chemicallysimilar on average to the underlyingmantle. %ecause oceanic lithosphere issubstantially cooler, its density is higher,

and it therefore has an ability to sink into the mantle below. "he sliding of an oceanic plate into the mantle is known asLsubduction,M as shown here beneath &outh America. As two plates pull apart at a midocean ridge, material from theasthenosphere rises to fill the gap, and some of this material melts to produce basaltic lava to form new oceanic crust on the

ocean floor. "he continental regions do not participate in the subduction process because of the buoyancy of the continentalcrust."he general principles of plate tectonics theory may be stated as followsK deformation occurs at the edges of the platesby three types of horiEontal motionDextension rifting or moving apart$, transform faulting horiEontal slippage along a largefault line$, and compression, mostly by subduction one plate plunging beneath another$ ./#xtension occurs where theseafloor is being pulled apart or split along rift Eones, such as along the axes of the FidAtlantic !idge and the #ast acific!ise.

"he idea that the continents had drifted apart was first suggested by a creationist, Antonio &nider. 6 He observed from thestatement in Genesis !/-;!6  about God?s gathering together the seas into one place that at that point in earth history theremay have been only a single landmass. He also noticed the close fit of the coastlines of western Africa and eastern &outh

 America. &o he proposed that the breakup of that supercontinent with subse7uent horiEontal movements of the newcontinents to their present positions occurred catastrophically during the lood.However, his theory went unnoticed, perhapsbecause +arwin?s book, which was published the same year, drew so much fanfare. "he year /1@0 was a bad year for attention to be given to any other new scientific theory, especially one that supported a creation view of earth history. And italso didn?t help that &nider published his book in rench.8t wasn?t until the early twentieth century that the theory of continental drift was acknowledged by the scientific community, through a book by Alfred *egener, a Germanmeteorologist.2 However, for almost @ years the overwhelming ma4ority of geologists spurned the theory, primarily becausea handful of seismologists claimed the strength of the mantle rock was too high to allow continents to drift in the manner *egener had proposed. "heir estimates of mantle rock strength were derived from the way seismic waves behave as theytraveled through the earth at that time.or this halfcentury the ma4ority of geologists maintained that continents werestationary, and they accused the handful of colleagues who promoted the drift concept of indulging in pseudoscientific

fantasy that violated basic principles of physics.

%ecause of the scientific community?scommitment to the uniformitarianassumptions and framework for earthhistory, most geologists take for grantedthat the movement of the earth?s plateshas been slow and gradual over long

eons. After all, if today?s measured ratesof plate driftDabout .@5J in 65/@ cm$per yearDare extrapolated uniformlyback into the past, it re7uires about /million years for the ocean basins andmountain ranges to form. And this rateof drift is consistent with the estimated>.1 mi2 6 km2$ of molten magma thatcurrently rises globally each year tocreate new oceanic crust.J9n the other hand, many other observations areincompatible with slowandgradualplate tectonics. *hile the seafloor surface is relatively smooth, Eebrastripe

B 8nstead, the magnetic polaritychanges rapidly and erratically down the drillholes. "his is contrary to what would be expected with slowandgradualformation of the new oceanic crust accompanied by slow magnetic reversals. %ut it is 4ust what is expected with extremelyrapid formation of new oceanic crust and rapid magnetic reversal during the lood, when rapid cooling of the new crustoccurred in a highly nonuniform manner because of the chaotic interaction with ocean water.urthermore, slowandgradualsubduction should have resulted in the sediments on the floors of the trenches being compressed, deformed, and thrustfaulted, yet the floors of the eruChile and #ast Aleutian "renches are covered with soft, flatlying sediments devoid of compressional structures.1 "hese observations are consistent, however, with extremely rapid subduction during the lood,followed by extremely slow plate velocities as the floodwaters retreated from the continents and filled the trenches withsediment.8f uniformitarian assumptions are discarded, however, and &nider?s original proposal for continental LsprintM duringthe lood is adopted, then a catastrophic plate tectonics model explains everything that slowandgradual plate tectonicsdoes, plus most everything it can?t explain.0  Also, a 2+ supercomputer model of processes in the earth?s mantle has

demonstrated that tectonic plate movements can indeed be rapid and catastrophic when a realistic deformation model for mantle rocks is included./  And, even though it was developed by a creation scientist, this supercomputer 2+ platetectonics modeling is acknowledged as the world?s best.//"he catastrophic plate tectonics model of Austin et al./6 beginswith a prelood supercontinent surrounded by cold oceanfloor rocks that were denser than the warm mantle rock beneath."o initiate motion in the model, some sudden trigger LcracksM the ocean floors ad4acent to the supercontinental crustal block,so that Eones of cold oceanfloor rock start penetrating vertically into the upper mantle along the edge of most of thesupercontinent./2"hese vertical segments of oceanfloor rock correspond to the leading edges of oceanic plates. "hesevertical Eones begin to sink in conveyorbelt fashion into the mantle, dragging the rest of the ocean floor with them. "hesinking slabs of ocean plates produce stresses in the surrounding mantle rock, and these stresses, in turn, cause the rock tobecome more deformable and allow the slabs to sink faster. "his process causes the stress levels to increase and the rockto become even weaker. "hese regions of rock weakness expand to encompass the entire mantle and result in acatastrophic runaway of the oceanic slabs to the bottom of the mantle in a matter of a few weeks. />"he energy for drivingthis catastrophe is the gravitational potential energy of the cold, dense rock overlying the less dense mantle beneath it at thebeginning of the event. At its peak, this runaway instability allows the subduction rates of the plates to reach amaEing

5n !)%- ,ntonio nider proposed that rapid* horiontal divergence of crustal plates occurred during lood. Modern platetectonics theory is now conflated with assumptions of uniformity of rate and ideas of continental Ddrift. Catastrophic platetectonics theories* such as nider proposed more than a century ago* appear capable of e4plaining a wide variety of data9including creationists and geologic data which the slow tectonics theories are incapable of e4plaining. We would like to propose a catastrophic plate tectonics theory as a framework for Earth history. Geophysically* we begin with a pre0lood earth differentiated into core* mantle* and crust* with the crust horiontally differentiated into sialic craton and mafic oceanfloor. 3he lood was initiated as slabs of oceanic floor broke loose and subducted along thousands of kilometers of pre0lood continental margins. Feformation of the mantle by these slabs raised the temperature and lowered the viscosity of themantle in the vicinity of the slabs. , resulting thermal runaway of the slabs through the mantle led to meters0per0second mantle convection. Cool oceanic crust which descended to the coreBmantle boundary induced rapid reversals of the earth2smagnetic field. arge plumes originating near the coreBmantle boundary e4pressed themselves at the surface as fissureeruptions and flood basalts. low induced in the mantle also produced rapid e4tension along linear belts throughout the sea

floor and rapid horiontal displacement of continents. Apwelling magma =ettisoned steam into the atmosphere causing intense global rain. @apid emplacement of isostatically lighter mantle material raised the level of the ocean floor* displacing ocean water onto the continents. When virtually all the pre0lood oceanic floor had been replaced with new* less0dense*less0subductable* oceanic crust* catastrophic plate motion stopped. ubse:uent cooling increased the density of the new ocean floor* producing deeper ocean basins and a reservoir for post0lood oceans. edimentologically* we begin with asubstantial reservoir of carbonate and clastic sediment in the pre0lood ocean. Furing the lood hot brines associated withnew ocean floor added precipitites to that sediment reservoir* and warming ocean waters and degassing magmas added carbonates9especially high magnesium carbonates. ,lso during the lood* rapid plate tectonics moved pre0lood sediments toward the continents. ,s ocean plates subducted near a continental margin* its bending caused upwarping of sea floor* and its drag caused downwarping of continental crust* facilitating the placement of sediment onto the continental margin. 'nce there* earth:uake0induced sea waves with ocean0to0land movement redistributed sediment toward continental interiors. @esulting sedimentary units tend to be thick* uniform* of unknown provenance* and e4tend over regional* inter0regional* and even continental areas.&hop )ow

 Age#ntroduction#arly in the history of geology, it was common to appeal to the lood described in Genesis to explain the origin of most or allrocks and fossils for example, %urnet,/ &teno,6 *histon,2 *oodward>$. 8n such theories the lood was typicallyrecogniEed as a catastrophic event of global proportions. "he earth?s crust was typically pictured as dynamic and capable of rapid vertical and horiEontal motions on local, regional, and global scales. However, especially with the influential works of Hutton@,J and then yell,B the lood began to play an increasingly less important role in historical geology during thenineteenth century. "heories of gradualism increased in popularity as theories of catastrophism waned. 8deas of pastcatastrophic geology were replaced with ideas of constancy of present gradual physical processes. 8deas of globalscaledynamics were replaced with ideas of local erosion, deposition, extrusion, and intrusion. 8deas of rapid crustal dynamicswere replaced by ideas of crustal fixityDwith only imperceptibly slow vertical subsidence and uplift being possible. &o

complete was the success of gradualism in geology that ideas of flood geology were nowhere to be found among the#nglishspeaking scientists of the world by /1@0,1 or rarely found at best.09ne of the last holdouts for flood geology was alittleknown work published by Antonio &niderellegrini/Dironically enough the same year +arwin published the 'rigin of pecies. 8ntrigued by the reasonably good fit between land masses on either side of the Atlantic ocean, &nider proposedthat the earth?s crust was composed of rigid plates which had moved horiEontally with respect to one another. &nider mayhave been the first to propose some of the main elements of modern plate tectonics theory. &nider also proposed that thehoriEontal divergence had been rapid and had occurred during the lood. 8t appears, then, that the first elaboration of platetectonics theory was presented in the context of catastrophic flood geology. 8t also seems that a substantial amount of thetwentieth century opposition to plate tectonics was due to the fact that geologists were, by then, firmly predisposed tobelieve that the earth?s crust was horiEontally fixed. "he catastrophism school of geology was the first to propose platetectonicsQ the gradualist school was the first ma4or opponent to plate tectonics. However, by the time plate tectonics wasfinally accepted in the (nited &tates in the late /0Js, gradualism had become a part of plate tectonics theory as well.!ather than &nider?s rapid horiEontal motion an the scale of weeks or months, modern geology accepted a plate tectonicstheory with horiEontal motion on the scale of tens to hundreds of millions of years.%ecause of the enormous explanatory and

predictive success of the plate tectonics model reviewed in *ise//,

/6$, we feel that at least some portion of plate tectonicstheory should be incorporated into the creation model. 8t appears that taking the conventional plate tectonics model andincreasing the rate of plate motion neither deprives plate tectonics theory of its explanatory and predictive success, nor doesit seem to contradict any passages of Genesis. "herefore, following the example of Antonio &nider we would like to proposea model of geology which is centered about the idea of rapid, horiEontal divergence of rigid crustal plates that is, rapid platetectonics$ during the lood. *e feel that this model is not only capable of the explanatory and predictive success of conventional plate tectonics, but is also capable of clarifying a number of scriptural claims and explaining some physicaldata unexplained by conventional plate tectonics theory.8t is important to note, however, that our model is still in its formative stages, and is thus incomplete. *hat is presented hereis a basic framework upon which more theory can be built. *e anticipate that a substantial amount of work is still needed toexplain all the salient features of this planet?s rocks and fossils.

evidence of life on earth completely. "he current earth has a coreSmantleScrust division according to the successively lower density of its components. 8f this differentiation had occurred by any natural means, the gravitational potential energyreleased by the heavier elements relocating to the earth?s interior would produce enough heat to melt the earth?s crust andvaporiEe the earth?s oceans. 8f differentiation of the earth?s elements did occur with its associated natural release of energy,it is reasoned that it most certainly occurred before the creation of organisms at the latest +ay 2 of the Creation week$.&econdly, even though such a differentiation could have been performed without the LnaturalM release of gravitationalpotential energy, the alreadydifferentiated earth?s interior also provides a natural driving mechanism for the rapid tectonicsmodel here described."he earth?s mantle appears to have been less viscous than it seems to be at present%aumgardner /1,/0,6$. "his is to allow for the thermal runaway instability which we believe produced the rapid platetectonic motion we are proposing.6/*ith regard to the earth?s crust, we believe that there was a distinct horiEontaldifferentiation between oceanic and continental crust, very much as there is today. irst, we believe that before the loodbegan, there was stable, sialic, cratonic crust. *e have three ma4or reasons for this conclusionKmuch Archean sialic material exists which probably is below the preloodSlood boundary. "his would indicate that sialicmaterial was available in prelood timesQ

the existence of lowdensity, low temperature LkeelsM beneath existing cratons66 implies that the cratons have persistedmore or less in their present form since their differentiation. 8t also argues that little or no mantle convection has disturbedthe upper mantle beneath the cratonsQ andif the prelood cratons were sialic and the prelood ocean crust was mafic, thenbuoyancy forces would provide a natural means of supporting craton material above sea levelDthus producing dry land onthe continents.&econd, we believe that the prelood ocean crust was maficDmost probably basaltic. 9nce again threereasons exist for this inferenceKprelood basaltic ocean crust is suggested by ophiolites containing pillow basalts and presumed ocean sediments$ whichare thought to represent pieces of ocean floor and obducted onto the continents early in the loodQif, as claimed above, the prelood craton was sialic, then buoyancy forces would make a mafic prelood ocean crust into anatural basin for ocean water. "his would prevent ocean water from overrunning the continentsQ andif, as claimed above, the continents were sialic, mafic material would be necessary to drive the subduction re7uired in our lood model.)re<&lood sediments*e believe that there was a significant thickness of all types of sediments already available on the earth by the time of thelood. *e have three reasons for this positionK

biologically optimum terrestrial and marine environments would re7uire that at least a small amount of sediment of eachtype had been created in the Creation weekQ

 Archean probable prelood$ and roteroEoic sediments contain substantial 7uantities of all types of sedimentsQ andit may not be possible to derive all the lood sediments from igneous andSor metamorphic precursors by physical andchemical processes in the course of a single, yearlong lood.*e believe that substantial 7uantities of very fine detrital carbonate sediment existed in the prelood oceans. "his isdeduced primarily from the fact that not enough bicarbonate can have been dissolved in the prelood ocean andSor provided by outgassing during the loodDsee below$ to have produced the lood carbonates.&uch 7uantities of carbonate as we believe to have existed in the prelood ocean would mean that there was a substantialbuffer in the prelood oceanDperhaps contributing to a very stable prelood ocean chemistry. "he existence of large7uantities of mature or nearly mature prelood 7uartE sands might explain the otherwise somewhat mysterious clean,mature nature of early aleoEoic sands.&lood Dynamics#nitiation

"here has been considerable discussionDboth reasonable and fancifulDabout what event might have initiated the lood.Considerations range fromthe direct hand of 8ntelligent +esigner %aumgardner 62,6>, Forton6@,6J,6B,61,60,2,2/$Qthe impact or nearmiss of an astronomical ob4ect or ob4ects such as asteroids,26 meteorites,22 a comet,2>,2@ a comet or -enus,2J -enus and Fars,2B Fars,21 Fars, Ceres, and :upiter,20 another moon of earth,> and a star Q>/some purely terrestrial event or events, such as fracturing of the earth?s crust due to drying>6 or radioactive heatbuildup,>2 rapid tilting of the earth due to gyro turbulence >> or ice sheet buildup,>@ and natural collapse of rings of iceQ>J,>B or various combinations of these ideas.*e feel that the lood was initiated as slabs of oceanic crust broke loose and subducted along thousands of kilometers of prelood continental margins. *e are, however, not ready at this time to speculate on what event or events might haveinitiated that subduction. *e feel that considerable research is still needed to evaluate potential mechanisms in the light of how well they can produce global subduction.Su0duction

 At the very beginning of plate motion, subducting slabs locally heated the mantle by deformation, lowering the viscosity of the mantle in the vicinity of the slabs. "he lowered viscosity then allowed an increase in subduction rate, which in turnheated up the surrounding mantle even more. *e believe that this led to a thermal runaway instability which allowed for meterspersecond subduction, as postulated and modeled by %aumgardner .>1,>0 8t is probable that this subductionoccurred along thousands of kilometers of continental margin. "he bending of the ocean plate beneath the continent wouldhave produced an abrupt topographic low paralleling the continental margin, similar to the ocean trenches at the eastern,northern, and western margins of the acific 9cean.

 As ocean lithosphere subducted, it would have produced rapid extension along linear belts on the ocean floor tens of thousands of kilometers long.

 As Forton/ points out, most lood sediments are found on the continents and continental margins and not on the oceanfloor where one might expect sediments to have ended up. 9ur model provides a number of mechanisms for thetransportation of ocean sediments onto the continents where they are primarily found today. irst, subducting plates wouldtransport sediments toward the subduction Eones and thus mostly towards the continents in a conveyorbelt fashion.&econd, as the ocean plates were forced to 7uickly bend into the earth?s interior, they would warp upward outboard of thetrench. "his would raise the deep sea sediments above their typical depth, which in turn reduces the amount of workre7uired to move sediments from the oceans onto the continents. "hird, rapid plate subduction would warp the continentalplate margin downward. "his again would reduce the amount of energy needed to move sediments onto the continent fromthe ocean floor. ourth, as more and more of the cold prelood ocean lithosphere was replaced with hotter rock from below,the ocean bottom is gradually elevated. "his again reduces the work re7uired to move sediments from the oceans to thecontinents. ifth, as ocean lithosphere is subducted, ocean sediments would be scraped off, allowing sediments to beaccreted to andSor redeposited on the continent. &ixth, wave for example, tsunami$ refraction on the continental shelf wouldtend to transport sediments shoreward. &eventh, it is possible that some amount of tidal resonance may have beenachieved.//,/6,/2 "he resulting easttowestdominated currents would tend to transport sediments accumulated on

eastern continental margins into the continental interiors. !esulting sedimentary units have abundant evidence of catastrophic deposition/>, and tend to be thick, uniform, of unknown provenance, and extending over regional, interregional, and even continental areas./@(olcanic acti/ity"he volcanism associated with rapid tectonics would have been of unprecedented magnitude and worldwide extent, butconcentrated in particular Eones and sites.

At the same time, the heating and melting of subducted sediments should have produced explosive sialicvolcanism continentward of the subduction Eone such as is seen in the Andes Fountains of &outh America, the CascadeFountains of the (nited &tates, and the Aleutian, :apanese, 8ndonesian, and )ew ;ealand 8slands of the acific$.

Earth4uake acti/ity"he rapid bending of elastic lithosphere and rapid interplate shear of plates at subduction Eones as well as abrupt phasetransitions as subducting plates are rapidly moved downward would be expected to produce fre7uent, highintensityearth7uakes at the subduction Eones.

"he LclassicalM model for regional metamorphic Eones presupposes elevated temperatures and pressures due to deep burialand deformationStectonic forces over large areas over millions of yearsDan apparent insurmountable hurdle for thecreationist framework. 9ne diagnostic metamorphic mineral is garnet, and variations in its composition have long beenstudied as an indicator of metamorphic grade conditions. &uch compositional variations that have been detected betweenand within grains in the same rock strata are usually explained in terms of cationic fractionation with changing temperatureduring specific continuous reactions involving elemental distribution patterns in the rock matrix around the crystalliEinggarnet. Garnet compositions are also said to correlate with their metamorphic grade. However, contrary evidence has beenignored. Compositional patterns preserved in garnets have been shown to be a reflection of compositional Eoning in theoriginal precursor minerals and sediments. Compositional variations between and within garnet grains in schists that are

typical metapelites at 3oongarra in the )orthern "erritory, Australia, support this minority viewpoint. %oth homogeneous andcompositionally Eoned garnets, even together in the same hand specimen, display a range of compositions that wouldnormally reflect widely different metamorphic grade and temperature conditions during their supposed growth. "hus thema4ority viewpoint cannot explain the formation of these garnets. 8t has also been demonstrated that the solidsolidtransformation from a sedimentary chlorite precursor to garnet needs only low to moderate temperatures, whilecompositional patterns only reflect original depositional features in sedimentary environments. "hus catastrophicsedimentation, deep burial and rapid deformationStectonics with accompanying low to moderate temperatures and pressuresduring, for example, a global lood and its aftermath have potential as a model for explaining the LclassicalM Eones of progressive regional metamorphism.#ntroduction9f the two styles of metamorphism, contact and regional, the latter is most often used to argue against the youngearthcreationlood model. 8t is usually envisaged that sedimentary strata over areas of hundreds of s7uare kilometers weresub4ected to elevated temperatures and pressures due to deep burial and deformationStectonic forces over millions of years."he resultant mineralogical and textural transformations are said to be due to mineral reactions in the original sediments

under the prevailing temperaturepressure conditions.9ften, mapping of metamorphic terrains has outlined Eones of stratacontaining mineral assemblages that are believed to be diagnostic and confined to each Eone respectively. 8t is assumedthat these mineral assemblages reflect the metamorphic transformation conditions specific to each Eone, so that bytraversing across these metamorphic Eones higher metamorphic grades due to former higher temperaturepressureconditions$ are progressively encountered. Amongst the metamorphic mineral assemblages diagnostic of each Eone arecertain minerals whose presence in the rocks is indicative of each Eone, and these are called index minerals. Garnet is oneof these key index minerals. Across a metamorphic terrain, the line along which garnet first appears in rocks of similar composition is called the garnet isograd Lsame metamorphic gradeM$ and represents one boundary of the garnet Eone. *ithincreasing metamorphic grade and in other Eones, garnet continues to be an important constituent of the mineralassemblages.*arnet Com"ositions-ariation in garnet compositions, particularly their Fn9 content, was for a long time used as an estimator of regionalmetamorphic grade. Goldschmidt/ first noted an apparent systematic decrease in Fn9 content with increase inmetamorphic grade, a relationship which he attributed to the incorporation of the ma4or part of the rock Fn9 in the earliestformed garnet. Fiyashiro6 and #ngel and #ngel2 also followed this line of thought, Fiyashiro suggesting that the larger Fn6 ions were readily incorporated in the garnet structure at the lower pressures, whereas at higher pressures smaller e6 and Fg6 were preferentially favored. "hus it was proposed that a decrease in garnet Fn9 indicated an increase ingrade of regional metamorphism. ambert> produced corresponding evidence for a decrease in garnet Ca9 with increasingmetamorphic grade. &turt@ demonstrated in somewhat pragmatic fashion what appeared to be a general inverserelationship between Fn9

depend not only on pressuretemperature variation but also to changes in the compositions of the different componentswithin its matrix as these responded to changing metamorphic grade. Albee,1 like 3retE and rost,0 examined elementaldistribution coefficients in garnetbiotite pairs as possible grade indicators, but concluded that results were complex ande7uivocal, and suggested that metamorphic e7uilibrium was fre7uently not attained. &imilarly, #vans/suggested caution inthe interpretation of increasing garnet Fg9 as indicating increasingly higher pressures of metamorphism. He pointed outthat the volume behavior of Fge exchange relations between garnet and other common silicates indicates that, for givenbulk compositions, the Fge ratios in garnet will decrease with pressure.*ith the advent of the electron probemicroanalyEer, it became possible to detect compositional variations even within mineral grains including garnet, whereoften it was found that traversing from cores to rims of grains, the Fn9 and Ca9 contents decreased with a concomitantincrease in e9 and Fg9.// Hollister /6 concluded that this Eoning arose by partitioning of Fn9 in accordance with the!ayleigh fractionation model between garnet and its matrix as the former grew. erhaps more importantly he drew attentionto the preservation of such Eones that remained unaffected by diffusion, and hence une7uilibrated, throughout the later 

stages of the metamorphism that was presumed to have induced their growth. Concurrently, Atherton and#dmunds/2 suggested that the Eoning patterns reflected changing garnetmatrix e7uilibrium conditions during growth andSor polyphase metamorphism, but that, once formed, garnet and its Eones behaved as closed systems unaffected by changes inconditions at the periphery of the growing grain."hrough his own work, and that of Chinner /> andHutton,/@  Atherton/J drew attention to the presence of garnets of 7uite different compositions in rocks of similar grade, andsometimes in virtual 4uxtaposition. His conclusion was that the Fn9 content, and indeed the whole divalent cationcomponent, of garnet was substantially a reflection of host rock composition and that any simple tie between garnetcomposition and metamorphic grade was unlikely. &ubse7uently Atherton/B suggested that Eoning and progressivechanges in garnet compositions were due to changes in distribution coefficients of the divalent cations with increase ingrade, and considered that Lanomalies in the se7uence were$ explicable in terms of variations in the compositions of thehost rock.MFller and &chneider /1 found that the Fn9 content of garnet reflected not only metamorphic grade andchemistry of the host rocks, but also their oxygen fugacity. "hey re4ected Hollister?s !ayleigh fractionation model andconcluded that decrease in Fn, and concomitant increase in e, in garnet with increasing grade stemmed from aprogressive reduction in oxygen fugacity. Hsu,/0 in his investigation of phase relations in the AlFne&i9H system, had

found that the stability of the almandine endmember is strongly dependent on oxygen fugacity, and is favored byassemblages characteriEed by high activity of divalent e. 8n contrast, the activity of divalent Fn is less influenced by higher oxygen fugacity. "hus Fller and &chneider 6 concluded that the observed decrease in Fn in garnet with increasingmetamorphic grade is due to the buffering capacity of graphite present near nucleating garnets. *ith increasing grade thegraphite buffer increasingly stabiliEes minerals dependent on low oxygen fugacity, that is, almandine is increasingly formedinstead of spessartine. Fller and &chneider also noted that some of their garnets were not Eoned, but exhibitedinhomogeneities distributed in irregular domains throughout the garnet grains.Fiyashiro and &hido, 6/ in a substantiallytheoretical treatment, concluded that the principal factor controlling successive garnet compositions is the amount andcomposition of the garnet already crystalliEed, since the matrix will be correspondingly depleted in the oxides present in theearlierformed garnet. Also using a theoretical approach, Anderson and %uckley66 showed that, for Lreasonable diffusioncoefficients and boundary conditions,M observed Eoning profiles in garnets could be explained 7uite ade7uately by diffusionprinciplesK that given original homogeneities in the parent rock, the interplay of diffusion phenomena could explain variationof Eoning profiles in separate grains of an individual mineral species in domains as small as that of a hand specimen."racy,!obinson, and "hompson62 noted that garnets from metamorphosed pelitic assemblages show, in different metamorphicEones,element distribution patterns that are complex functions of rock bulk composition, specific continuous reactions in

which garnet is involved, " history of the rock, homogeneous diffusion rates with garnet, and possibly also the availabilityof metamorphic fluids at the various stages of garnet development."hey applied preliminary calibrations of garnetbiotite and garnetcordierite eFg exchange reactions and several eFgFn continuous mineral reactions to the results of very detailed studies of Eoned garnets in order to evaluate changing "conditions during prograde and retrograde metamorphism in central Fassachusetts (&A$.&tanton,6>,6@,6J,6B in his studiesof %roken Hill )ew &outh *ales, Australia$ banded iron formations, suggested that the garnets represented insitu transformation of somewhat manganiferous chamositic septachlorite, and that any Eoning reflected the original ooliticstructure of the sedimentary chamosite. 8n a further study, &tanton and *illiams 61concluded that, because compositionaldifferences occur on a fine /56 mm$ scale in garnets within a simple onecomponent matrix 7uartE$, garnet compositionsmust faithfully reflect original compositional variations within the chemical sediments, and not represent variations inmetamorphic grade.FcAteer 60 demonstrated the presence in a garnetmica schist of two compositionally and texturallydistinct garnet types, which she attributed to a se7uence of mineral reactions that proceeded with changing thermal historyof the rock. 9f the two types, one was coarsegrained and Eoned Fn9 and Ca9 decreasing towards grain margins$, whilethe other was finegrained and essentially uniform in composition. Attainment of chemical e7uilibrium between all garnets

and their rock matrix, but maintenance of dise7uilibrium within large garnets, appears to have been assumed.8n a review of research on compositional Eoning in metamorphic minerals, "racy2 ignored &tanton?s demonstration that the compositionalEoning in garnets can only be explained in some metamorphic rocks as faithful reflections of original compositionalvariations within the precursor minerals and sediments, and not as a function of variations in metamorphic grade or cationicsupply during crystal growth. 8nstead, "racy summariEed the various models already proposedDcationic fractionationparticularly of Fn resulting in variations in the supply of cations$ with changing temperatures during progressivemetamorphism, and reaction partitioning of cations which depends upon the exact mineralogical composition of the reservoir or matrix surrounding any one garnet grain, especially relative proportions of matrix minerals that are in direct reactionrelation with a garnet grain. "hese models both correlate changes in garnet composition with increasing metamorphic grade,relying on mineral reactions and diffusion of cations to explain compositional Eoning trends, which it is envisaged change asmineral reactions and temperatures change."his is still the consensus viewpoint. oomis,2/ &pear,26 and &pear, 3ohn,lorence, and Fenard,22 for example, insist that metamorphic garnets undergo a form of fractional crystalliEation whichinvolves fractionation of material into the interior of a crystalliEing garnet grain with conse7uent change in the effective bulkcomposition, the Eoning profile preserved in the garnet being a function of the total amount of material that has fractionated.urthermore, &pear insists that because intracrystalline diffusion is so slow at these conditions, the interior of the garnet iseffectively isolated from chemical e7uilibrium with the matrix. &pear then points to the work of Iardley 2> to insist that withincreasing temperatures intracrystalline diffusion within garnet grains becomes more rapid until eventually all chemicalEoning is erased. 8ndeed, Iardley claimed to have found that at the temperatures of staurolite and sillimanite grademetamorphism internal diffusion of cations within garnet grains is sufficient to eliminate the Eoning that developed duringearlier growth.Iardley also rightly pointed out that the fractionation models for garnet Eoning assume that that diffusion isnegligible at lower metamorphic grades. "hat there is negligible cationic diffusion in garnet at lower grades is amplydemonstrated in the garnets described by 9lympic and Anderson,2@ whose pattern of chemical Eoning coincided with

that compositional Eoning in garnets has been due to mineral reactions and cationic fractionation, and that at higher gradesthe compositional Eoning is homogeniEed by diffusion, &tanton and *illiams J0 have clearly shown at %roken Hill that at thehighest grades of metamorphism the compositional Eoning in garnets is neither homogeniEed nor the result of either mineralreactions or cationic fractionation, but an accurate preservation of compositional Eoning in the original precursor oolites inthe precursor sediment. )evertheless, while their conclusion is not 7uestioned, their timescale is, because it strains credulityto suppose that the original pattern of chemical sedimentation could have been preserved with the Lutmost delicacyM througha presumed period of /.1 billion years.*hat is e7ually amaEing is the discovery by &tanton B of distinctly hydrous L7uartEM inwellbedded 7uartEmuscovitebiotitealmandinespinel rocks also in the %roken Hill metamorphic terrain. He comments thatit seems LremarkableM that this silica should still retain such a notably hydrous nature after /.1 billion years that includedrelatively highgrade that is, high temperaturepressure$ metamorphismO )ot only does this discovery confirm thatmetamorphic 7uartE has been produced by dehydration and transformation in situ of precursor silica gel andSor chert, butthat the temperatures, pressures and timescales normally postulated are not necessarily re7uired.&tantonB/ maintains thatit has long been recogniEed that particular clays and Eeolites derive in many instances from specific precursors. ikewise, itis selfevident and unavoidable that many metamorphosed bedded oxides including 7uartE$, together with carbonates and

authigenic silicates, such as the feldspars, have derived from sedimentarySdiagenitic precursors, and the establishmentthereby of this precursor derivation for at least some regional metamorphic minerals is a principle, not an hypothesis. *hat&tanton then proceeds to show is how this principle applies to the broader spectrum of metamorphic silicates, includingalmandine garnet.He points to his earlier evidenceB6,B2 that almandine has derived directly from a chamositic chloritecontaining very finely dispersed chemical &i96, and suggests that dehydration and incorporation of this silica into the chloritestructure induces in situ transformation to the garnet structure. urthermore, instability induced by Fn, and perhaps small7uantities of Ca, in the structure may predispose the chlorite to such transformation. Any silica in excess of the re7uirementsof this process aggregates into small rounded particles within the garnet grainDthe 7uartE LinclusionsM that are almost acharacteristic feature of the garnets of metapelites, including the garnets at 3oongarra. &tanton then supports his contentionwith electron microprobe analyses of several hundred chlorites, from metamorphosed stratiform sulfide deposits in Canadaand Australia, and of almandine garnets immediately associated with the chlorites. "hese analyses plot sidebyside onternary diagrams, graphically showing the compositional similarities of the chlorites in these original chemical sediments tothe garnets in the same rock that have been produced by metamorphism. "his strongly suggests that the process was oneof a solidsolid transformation, with excess silica producing 7uartE Linclusions.M As &tanton insists, why should theseinclusions be exclusively 7uartE if these garnets had grown from mineral reactions within the rock matrix, because the latter 

contains abundant muscovite, biotite, and other minerals in addition to 7uartE, minerals that should also have beenLincludedM in the growing garnet grains&tanton and *illiamsB> have conclusively demonstrated that the compositionalEones within individual garnet porphyroblasts reflect compositional Eoning in precursor sedimentary mineral grains. "hus, if primary depositional$ compositional features have led to a mimicking of metamorphic grade,B@,BJ then it has beenshownBB,B1,B0 that the classical Eones of regional metamorphic mineral assemblages may instead reflect facies of clay andclaychlorite mineral sedimentation, rather than variations in pressuretemperature conditions in subse7uent metamorphism.&tanton1goes on to say that if regional metamorphic silicates do develop principally by transformation and grain growth,the problem of the elusive metamorphic reaction in the natural milieu is resolved. "here is no destabiliEing of large chemicaldomains leading to extensive diffusion, no widespread reaction tending to new e7uilibria among minerals. "raditionally it hasbeen supposed that as metamorphism progressed each rock unit passed through each successive grade, but the commonlack of evidence that LhighgradeM Eones have passed through all the mineral assemblages of the LlowergradeM Eones cannow be accounted for. "he real metamorphic grade indicators are then not the hypothetical intermineral reactions usuallypostulated, but the relevant precursor transformations, which may be solidsolid or in some cases gelsolid. &tantonconcludes that it would be going too far to maintain that there was no such thing as a regional metamorphic mineral

reaction, or that regional metamorphic e7uilibrium was never attained, but the role of metamorphic reactions in generatingthe bulk of regional metamorphic mineral matter is Lprobably, 7uite contrary to present belief, almost vanishingly small.M"heother key factor in elucidating regional metamorphic grades, Eones, and mineral compositions besides precursor mineralSsediment compositions would be the temperatures of precursor transformations, rather than the temperatures of presumed LclassicalM metamorphic mineral reactions. 8t is thus highly significant that dehydration and incorporation of silicainto the chlorite structure induces in situ transformation to garnet at only low to moderate temperatures and pressures thatare conceivable over short timescales during catastrophic sedimentation, burial, and tectonic activities. 8ndeed, therealiEation that the LclassicalM Eones of progressive regional metamorphism are potentially only a reflection of variations inoriginal sedimentation, as can be demonstrated in continental shelf depositional facies today, provides creationists with apotential scientifically satisfying explanation of regional metamorphism within their time framework, which includescatastrophic sedimentation, deep burial and rapid deformationStectonics with accompanying low to moderate temperaturesand pressures during, for example, the global lood and its aftermath.1/ConclusionsGarnets in the amphibolite grade schists at 3oongarra show wide compositional variations both within and between grains,even at the thin section scale, a pattern which is not consistent with the current consensus on the formation of metamorphicgarnets. !ather than elevated temperatures and pressures being re7uired, along with fractionational crystalliEation,elemental partitioning, and garnetmatrix reaction partitioning, the evidence at 3oongarra and in other metamorphic terrainsis consistent with solidsolid transformation at moderate temperatures of precursor sedimentary chlorite, complete withcompositional variations due to precursor oolites, into garnet such that the compositional variations in the precursor chloriteare preserved without redistribution via diffusion. "hese compositional variations in garnets contradict the LclassicalM viewthat particular compositions represent different metamorphic grade Eones, since at 3oongarra the compositional variationseven in single garnets span wide ranges of presumed metamorphic temperatures and grades.

explanation for progressive regional metamorphism, different grade Eones being imposed on original sedimentary strataover hundreds of s7uare kilometers due to elevated temperatures and pressures resulting from deep burial anddeformationStectonic forces over millions of years, has to be seriously 7uestioned. A feasible alternative is that these Eonesrepresent patterns of original precursor sedimentation, such as we see on continental shelves today.

sedimentation period involvedis believed to have closed witha ma4or change in climateandSor uplift of the ocean floor to form a new land surface."here often then followed, it is

"hus a new rock layer of perhaps an entirely different kind of sediment wasthen deposited. "his new layer would be expected to bury and preserve much of the previously eroded surface at theinterface between the lower rock layer and this newly deposited layer above.#n the *rand Canyon"herefore, this accepted scenario for earth history involves many uplifts and subsidences of land surfaces. &o where the

rock layers of the earth?s surface are exposed to view, as they are in the Grand Canyon of )orthern AriEona (&A$, wherethere are numerous different sedimentary rock layers laid down one upon another, there ought to be many buried erosionsurfaces found at the boundaries between the various individual rock layers. 8ndeed, the display on the Grand Canyon in theFuseum of )orthern AriEona in lagstaff diagrammatically shows how the land surface in the Grand Canyon area must havesubsided, been covered by the sea while sediments were being deposited, and then uplifted again with erosion taking place."his is depicted as happening at least five times during the development of the >, feet /,66 metres$ of horiEontalsedimentary rock layers now exposed in the walls of the Grand Canyon.Creationists do recogniEe significant erosionsurfaces between rock strata in the Grand Canyon, but unlike evolutionary geologists have concluded that these erosionbreaks do not represent large time breaks. 8ndeed, evolutionists currently assign more time to these erosion breaks, wherestrata may have been eroded away on these erosion surfaces and therefore are now missing, than to all the >, feet/,66 metres$ of horiEontal rock strata present in the Grand Canyon todayO*here erosion can clearly be seen to haveoccurred at these breaks between rock strata in the Grand Canyon, creationists maintain that the erosion was very rapid,facilitated in many cases by erosion occurring in soft, Nnonhardened? rock. Conse7uently, rather than having a land surfaceexposed for enormous periods of time after an ocean retreated, the same lood processes responsible for depositing thesedimentary layers were also capable of eroding significant thicknesses of both loose sediment and consolidated rock."he

nature of the debate concerning these socalled erosion breaks technically known as unconformities$ is brought into sharpfocus in statements made by representatives of each viewpoint. or example, +r. +avis Ioung, rofessor of Geology atCalvin College, Grand !apids, Fichigan, a Christian geologist who opposes the special creationSlood approach,writesKN"he presence of each unconformity is physical evidence that the Colorado lateau the area taking in the GrandCanyon$ experienced consolidation of sediments, uplift, and possibly gentle tilting, weathering of the uplifted surface to formsoil, and erosion by streams and wind before the sediments of the next formation rock layer$ were deposited.

Uranium9ne of the strongest arguments used to support the theory of a primitive reducing atmosphere is the character of uraniumdeposition, which is presumed to have changed with time, resulting in the apparent timerelated or timebound occurrence of the various types of uranium deposits.6>, 6@%ased on Holland?s@ calculation of the maximum partial pressure of oxygen for uraninite (96$ stability, it was concluded that the Archaean uraninite placer deposits of the *itwatersrand, &outh Africa and#lliot ake, Canada could not have formed under a significantly oxidiEing atmosphere. *hile controversy regarding theorigin of these two deposits has raged for many years, most geologists now accept the placer hypothesis whereby detritaluraninite was deposited in the 7uartE pebble conglomerates of alluvial fan or placer under reducing atmospheric conditions.8t is argued that because the uraninite appears to be detrital and only stable under reducing conditions, then atmosphericconditions, at the time of transport and deposition must have been reducing. 6@,6J However, the remarkable similaritybetween the subeconomic concentrations of detrital uraninite in the present day 8ndus -alley6B and that of the*itwatersrand, as well as other evidence, invalidates any such concept.8t would appear 7uite unnecessary to postulate areducing atmosphere for the transportation of detrital uraninite.61urthermore, 3imberley and +imroth/, // presentevidence against this placer hypothesis, comparing many of the characteristics of other ma4or uranium occurrences

T-E &OSS#' RECORD

Doesn3t the Order o &ossils in the Rock Record &a/or 'ong Ages5by +r. Andrew A. &nelling on &eptember 0, 6/Q last featured ebruary 6@, 6/>

3he fossil record is hardly Dthe record of lifein the geologic past that so many scientistsincorrectly espouse* assuming a long  prehistory for the earth and life on it.&hop )owossils are the remains, traces, or imprints of plants or animals that have been preserved

in the earth?s nearsurface rock layers atsome time in the past./ 8n other words,

fossils are the remains of  dead  animals and plants that were buried in sedimentary layers that later hardened to rock strata.&o the fossil record is hardly Lthe record of life in the geologic pastM that so many scientists incorrectly espouse, 6 assuminga long prehistory for the earth and life on it. 8nstead, it is a record of the  deathsof countless billions of animals and plants.

The &ossil Recordor many people, the fossil record is still believed to be Lexhibit AM for evolution. *hy %ecause most geologists insist thesedimentary rock layers were deposited gradually over vast eons of time during which animals lived, died, and then wereoccasionally buried and fossiliEed. &o when these fossiliEed animals and plants$ are found in the earth?s rock se7uences ina particular order of first appearance, such as animals without backbones invertebrates$ in lower layers followedprogressively upward by fish, then amphibians, reptiles, birds, and finally mammals e.g., in the Colorado lateau region of the (nited &tates$, it is concluded, and thus almost universally taught, that this must have been the order in which theseanimals evolved during those vast eons of time.However, in reality, it can only be dogmatically asserted that the fossil recordis the record of the order in which animals and plants were buried and fossiliEed. urthermore, the vast eons of time are

unproven and unproveable, being based on assumptions about how 7uickly sedimentary rock layers were deposited in theunobserved past. 8nstead, there is overwhelming evidence that most of the sedimentary rock layers were deposited rapidly.8ndeed, the impeccable state of preservation of most fossils re7uires the animals and plants to have been very rapidlyburied, virtually alive, by vast amounts of sediments before decay could destroy delicate details of their appearance andanatomy. "hus, if most sedimentary rock layers were deposited rapidly over a radically short period of time, say in acatastrophic global flood, then the animals and plants buried and fossiliEed in those rock layers may well have all lived atabout the same time and then have been rapidly buried progressively and se7uentially.urthermore, the one thing we canbe absolutely certain of is that when we find animals and plants fossiliEed together, they didn?t necessarily live together inthe same environment or even die together, but they certainly were buried together, because that?s how we observe themtodayO "his observational certainty is crucial to our understanding of the many claimed mass extinction events in the fossilrecord. )evertheless, there is also evidence in some instances that the fossils found buried together may represent animalsand plants that did once live together see later$.

,ass E!tinctions8n the present world, when all remaining living members of a particular type of animal die, that animal or plant$ is said tohave become extinct. Fost scientists incorrectly$ regard the fossil record as a record of life in the geologic past. &o, when in

the upward progression of strata the fossils of a particular type of animal or plant stop occurring in the record and there areno more fossils of that animal or plant in the strata above, or any living representatives of that animal or plant, mostscientists say that this particular creature went extinct many years ago. &adly, there are many animals and plants that areextinct, and we only know they once existed because of their fossiliEed remains in the geologic record. erhaps the mostobvious and famous example is the dinosaurs."here are distinctive levels in the fossil record where vast numbers of animalsand plants$ are believed to have become extinct. #volutionists claim that all these animals and plants$ must have died,been buried, and become extinct all at the same time. &ince this pattern is seen in the geologic record all around the globe,they call these distinctive levels in the fossil record mass extinctions. urthermore, because something must have happenedglobally to wipe out all those animals and plants$, the formation of these distinctive levels in the fossil record are calledmass extinction events. However, in the context of catastrophic deposition of the strata containing these fossils, this patternwould be a preserved conse7uence of the lood.)ow geologists have divided the geologic record into time periods,according to their belief in billions of years of elapsed time during which the sedimentary strata were deposited. "hus, thosesedimentary strata that were supposedly deposited during a particular time period are so grouped and named accordingly."his is the origin of names such as Cambrian, 9rdovician, &ilurian, +evonian, Carboniferous, ermian, "riassic, :urassic,

Cretaceous, and more."here are some /B mass extinction events in the fossil record recogniEed by geologists, from in thelate recambrian up until the late )eogene, L4ust before the dawn of written human history.M However, only eight of those areclassed as ma4or mass extinction eventsDend9rdovician, late+evonian, endermian, end"riassic, early:urassic, end:urassic, middleCretaceous, and endCretaceous. Fost people have probably heard about the endCretaceous massextinction event, because that?s when the dinosaurs are supposed to have been wiped out, along with about a 7uarter of allthe known families of animals. However, the endermian mass extinction event was even more catastrophic, because B@percent of amphibian families and 1 percent of reptile families were supposedly wiped out then, along with B@ to 0 percentof all preexisting species in the oceans.

Asteroid #m"acts and (olcanic Eru"tions&o what caused these mass extinction events #volutionary geologists are still debating the answer. "he populariEedexplanation for the endCretaceous mass extinction event is that an asteroid hit the earth, generating choking dust cloudsand giant tsunamis socalled tidal waves$ that decimated the globe and its climate, supposedly for a few million years. Alayer of clay containing a chemical signature of an asteroid is pointed to in several places around the globe as one piece of evidence, and the /6>mile 6 km$ wide Chicxulub impact crater in Fexico is regarded as Lthe scene of the crime.MHowever, at the same level in the geologic record are the massive remains of catastrophic outpourings of staggering7uantities of volcanic lavas over much of 8ndia, totally unlike any volcanic eruptions experienced in recent human history."he inatubo eruption in the hilippines in /00/ blasted enough dust into the atmosphere to circle the globe and cool thefollowing summer by /56VC, as well as gases which caused acid rain. Iet that eruption was only a tiny firecracker comparedto the massive, catastrophic 8ndian eruption. urthermore, volcanic dust has a similar chemical signature to that of anasteroid. 8nterestingly, even more enormous 7uantities of volcanic lavas are found in &iberia and coincide with the endermian mass extinction event.

*hat then should creationists make of these interpretations of the fossil and geologic evidence 9f course, we first need torecogniEe that both creationists and evolutionists start with presupposed assumptions, which they then use to interpret thepresently observed evidence. &o this difference of interpretations cannot be Lreligion vs. science,M as it is so oftenportrayed.urthermore, it needs to be noted that in the geologic record there are very thick se7uences of rock layers, foundbelow the main strata record containing prolific fossils, which are either totally devoid of fossils or only contain very rarefossils of microorganisms and minor invertebrates. 8n the creation framework of earth history, these strata would beclassified as creation and preflood. Also, a few fossils may also have been formed since the flood due to localiEed, residualcatastrophic depositional events, so flood geologists do not claim all fossils were formed during the flood.As already noted,the only dogmatic claim which can be made is that the geologic strata record the order in which animals and plants wereburied and fossiliEed. 8ndeed, fossiliEation under presentday conditions is exceedingly rare, so evolutionary geologistsapplying Lthe present is the key to the pastM have a real problem in explaining how the vast numbers of fossils in thegeologic record could have formed. "hus, the global destruction of all the prelood animals and plants by the yearlong

lood cataclysm alone makes sense of this fossil and geologic evidence though as noted above, a small percent of thegeological and fossil evidence is from postlood residual catastrophism$.8ndeed, not only did the animals and plants haveto be buried rapidly by huge masses of watertransported sediments to be fossiliEed, but the general vertical order of burialis also consistent with the flood. "he first fossils in the record are of marine animals exclusively, and it is only higher in thestrata that fossils of land animals are found, because the lood began in the ocean basins Lthe fountains of the great deepburst openM$ and the ocean waters then flooded over the continents. How else would there be marine fossils in sedimentarylayers stretching over large areas of the continents Added to this, Lthe floodgates of heavenM were simultaneously opened,and both volcanism and earth movements accompanied these upheavals.8n a global watery cataclysm, therefore, therewould be simultaneous wholesale destruction of animals and plants across the globe. "he tearing apart of the earth?s crustwould release stupendous outpourings of volcanic lavas on the continental scale found in the geologic record. "he resultantLwavesM of destruction are thus easily misinterpreted as mass extinction events, when these were 4ust stages of the single,yearlong, catastrophic global flood.8t is also significant that some fossiliEed animals and plants once thought to be extincthave in fact been found still alive, thus demonstrating the total unreliability of the evolutionary time scale. "he last fossiliEedcoelacanth a fish$ is supposedly J@ million years old, but coelacanths are still here, so where did they LhideM for J@ million

years "he *ollemi pine?s last fossil is supposedly /@ million years old, but identical living trees were found in /00>. "herecent burial and fossiliEation of these animals and plants, and the extinction of many other animals and plants, during thesingle flood thus makes better sense of all the fossil and geologic evidence.

Accounting or the Order o &ossils in the Rock Record#ven though the order of strata and the fossils contained in them sometimes extrapolated and interpolated$ has been madethe basis of the accepted millionsofyears system of geochronology and historical geology, the physical reality of the strataorder and the contained fossils is generally not in dispute. +etails of local strata se7uences have been carefully compiled byphysical observations during field work and via drillholes. Careful correlations of strata of the same rock types have thenbeen made between local areas and from region to region, often by physical means, so that the robustness of the overallfossil order and strata se7uence of the geologic record has been clearly established.8ndeed, it is now well recogniEed thatthere are at least six thick se7uences of fossilbearing sedimentary strata, known as megase7uences, which can be tracedright across the )orth American continent and beyond to other continents.2&uch globalscale deposition of sediment layerse.g., chalk and coal beds$ is, of course, totally inexplicable to uniformitarian longages$ geologists by the application of onlytoday?s slowandgradual geologic processes that only operate over local to regional scales. %ut it is powerful evidence of catastrophic deposition during the global flood. "hus, it is not the recogniEed order of the strata in the geologic record that is

in dispute, but rather the millionsofyears interpretation for the deposition of the sedimentary strata and their containedfossils.8t is true that the complete geologic record is hardly ever, if at all, found in any one place on the earth?s surface.(sually several or many of the strata in local se7uences are missing compared to the overall geologic record, but usuallyover a given region there is more complete preservation of the record via correlation and integration. However, 7uitecommonly there is little or no physical or physiographic evidence of the intervening period of erosion or nondeposition of the missing strata systems, suggesting that at such localities neither erosion nor deposition ever occurred there. Iet this isexactly what would be expected based on the creation account of the flood and its implications. 8n some areas onese7uence of sedimentary strata with their contained fossil assemblages would be deposited, and in other areas entirelydifferent strata se7uences would be deposited, depending on the source areas and directions of the water currentstransporting the sediments. &ome strata units would have been deposited over wider areas than others, with erosion insome areas but continuous deposition in others, even when intervening strata units were deposited elsewhere. "hus, as aresult of the complex interplay of currents, waves, and transported sediments with their entombed organisms, a variety of different types of sedimentary rocks and strata se7uences would have been laid down directly on the prelood stratase7uences and the crystalline basement that probably dates back to the creation itself. "hus the pattern of deposition of the

strata se7uences and their contained fossils is entirely consistent with the strata record the lood might be expected to haveproduced. 8n contrast, by using the present to interpret the past, evolutionary geologists have no more true scientificcertainty of their version of the unobservable, uni7ue historic events which they claim produced the geologicrecord.)evertheless, if the general order of the strata and their contained fossil assemblages is not generally in dispute,then that order in the strata se7uences still must reflect the geological processes and their timing responsible for theformation of the strata and their order. 8f, as is assiduously maintained here, the order in the fossil record does not representthe se7uence of the evolutionary development of life, then the fossil record must be explainable within the context of thetempo of geologic processes burying these organisms in the sediment layers during the global flood cataclysm. 8ndeed, boththe order of the strata and their contained fossils could well provide us with information about the prelood world, andevidence of the progress of different geological processes during the lood event. "here are a number of factors that havebeen suggested to explain the order in the fossil record in terms of the lood processes, rather than over the claimed longages.

)re<&lood %iogeogra"hy8f we look at today?s living biology, we find that across mountains such as the &ierra )evada of California, or in a trip fromthe &outh !im of the Grand Canyon down to the Colorado !iver, there are distinct plant and animal communities in differentlife or ecology Eones that are characteristic of the climates at different elevations. "hus, we observe cacti growing in desertEones and pines growing in alpine Eones rather than growing together. "herefore, 4ust as these lifeSecology Eones today canbe correlated globally all deserts around the world have similar plants and animals$, so too some fossil Eones and fossilcommunities may be correlated globally within the geologic record of the lood."hus it has been suggested that there couldwell have been distinct biological communities and ecological Eones in the prelood world that were spatially andgeographically separated from one another and that that were then se7uentially inundated, swept away, and buried as thelood waters rose. "his ecological Eonation model for the order of fossils in the geologic record > would argue that the lower

http://slidepdf.com/reader/full/asnelling-flood-geology 104/149

fossiliferous layers in the strata record must therefore represent the fossiliEation of biological communities at lower elevations and warmer climates, while higher layers in the geologic record must represent fossiliEation of biologicalcommunities that lived at higher elevations and thus cooler temperatures.%ased on the vertical and horiEontal distribution of certain fossil assemblages in the strata record, it has been concluded that the prelood biogeography consisted of distinctand uni7ue ecosystems which were destroyed by the lood and did not recover to become reestablished in the postloodworld of today. "hese include a floatingforest ecosystem consisting of uni7ue trees called lycopods of various siEes thatcontained large, hollow cavities in their trunks and branches and hollow rootlike rhiEomes, with associated similar plants. 8talso includes some uni7ue animals, mainly amphibians, that lived in these forests that floated on the surface of the prelood ocean.@ &patially and geographically separated and isolated from this floatingforest ecosystem were stromatolitereefs ad4acent to hydrothermal springs in the shallow waters of continental shelves making up a hydrothermalstromatolitereef ecosystem.J8n the warmer climates of the lowland areas of the prelood land surfaces, dinosaurs lived wheregymnosperm vegetation naked seed plants$ was abundant, while at high elevations inland in the hills and mountains where

the climate was cooler, mammals and humans lived among vegetation dominated by angiosperms flowering plants$.B "husthese gymnospermdinosaur and angiospermmammalman ecosystems or biomes$ were spatially and geographicallyseparated from one another on the prelood land surfaces. 8n chapter 6, the river coming out of the Garden of #den isdescribed as dividing into four rivers, which may imply the Garden of #den with its fruit trees and other angiosperms,mammals, and man$ was at a high point geographically, the rivers flowing downhill to the lowland swampy plains borderingthe shorelines where the gymnosperms grew and the dinosaurs lived. "his would explain why we don?t find human anddinosaur fossil remains together in the geologic record, dinosaurs and gymnosperms only fossiliEed together, andangiosperms only fossiliEed with mammals and man higher in the record separate from the dinosaurs and gymnosperms.8tcan therefore be argued that in a very general way the order of fossil LsuccessionM in the geologic record would reflect thesuccessive burial of these pre lood biological communities as the lood waters rose up onto the continents. "he loodbegan with the breaking up of the fountains of the great deep the breaking up of the prelood ocean floor$, so there wouldhave been a sudden surge of strong ocean currents and tsunamis picking up sediments from the ocean floor and movinglandward that would first of all have overwhelmed the stromatolite reefs in the shallow seas fringing the shorelines. "hisdestruction of the protected lagoons between the stromatolite reefs and the shorelines by these severe storms would have

then caused the strange animals that probably were uni7ue to these stromatolite reefs to be buried and thus preserved inthe lowermost lood strata directly overlaying the burial of the stromatolites.8ncreasing storms, tidal surges, and tsunamisgenerated by earth movements, earth7uakes, and volcanism on the ocean floor would have resulted in the progressivebreaking up of the floatingforest ecosystem on the ocean surface, and thus huge rafts of vegetation would have been sweptlandward to be beached with the sediment load on the land surfaces being inundated. "hus, the floatingforest vegetationwould have been buried higher in the strata record of the lood, well above the stromatolites and the strange animals thatlived with them. 9nly later, in the first /@ days of the lood, as the waters rose higher across the land surface, would thegymnospermdinosaurs ecosystem be first swept away and buried, followed later by the angiospermmammalmanecosystem that lived at higher elevations. eople would have continued to move to the highest ground to escape the risinglood waters, and so would not necessarily have been buried with the angiosperms and mammals. "hus the existence of these geographically separated distinct ecosystems in the prelood world could well explain this spatial separation andorder of fossiliEation in the geologic record of the lood.

Early %urial o ,arine Creatures"he vast ma4ority by number of fossils preserved in the strata record of the lood are the remains of shallowwater marineinvertebrates brachiopods, bivalves, gastropods, corals, graptolites, echinoderms, crustaceans, etc.$.1 8n the lowermost

fossiliferous strata Cambrian, 9rdovician, &ilurian, and +evonian$, the contained fossils are almost exclusively shallowwater marine invertebrates, with fish and amphibian fossils only appearing in progressively greater numbers in the higher strata.0 "he first fish fossils are found in 9rdovician strata, and in +evonian strata are found amphibians and the firstevidence of continentaltype flora. 8t is not until the Carboniferous Fississippian and ennsylvanian$ and ermian stratahigher in the geologic record that the first traces of land animals are encountered.%ecause the lood began in the oceanbasins with the breaking up of the fountains of the great deep, strong and destructive ocean currents were generated by theupheavals and moved swiftly landward, scouring the sediments on the ocean floor and carrying them and the organismsliving in, on, and near them. "hese currents and sediments reached the shallower continental shelves, where the shallowwater marine invertebrates lived in all their prolific diversity. (nable to escape, these organisms would have been sweptaway and buried in the sediment layers as they were dumped where the waters crashed onto the land surfaces beingprogressively inundated farther inland. As well as burying these shallowwater marine invertebrates, the sediments washedshoreward from the ocean basins would have progressively buried fish, then amphibians and reptiles living in lowland,swampy habitats, before eventually sweeping away the dinosaurs and burying them next, and finally at the highestelevations destroying and burying birds, mammals, and angiosperms.

-ydrodynamic Selecti/ity o ,o/ing 2ater Foving water hydrodynamically selects and sorts particles of similar siEes and shapes. "ogether with the effect of thespecific gravities of the respective organisms, this would have ensured deposition of the supposedly simple marineinvertebrates in the firstdeposited strata that are now deep in the geologic record of the lood. "he wellestablished LimpactlawM states that the settling velocity of large particles is independent of fluid viscosity, being directly proportional to thes7uare root of particle diameter, directly proportional to particle sphericity, and directly proportional to the difference betweenparticle and fluid density divided by fluid density./ Foving water, or moving particles in still water, exerts LdragM forces onimmersed bodies which depend on the above factors. articles in motion will tend to settle out in proportion mainly to their specific gravity or density$ and sphericity.8t is significant that the marine organisms fossiliEed in the earliest lood strata,such as the trilobites, brachiopods, etc., are very LstreamlinedM and 7uite dense. "he shells of these and most other marineinvertebrates are largely composed of calcium carbonate, calcium phosphate, and similar minerals which are 7uite heavyheavier than 7uartE, for example, the most common constituent of many sands and gravels$.

of hydraulic action are really only valid generally, rather than universally. urthermore, local variations and peculiarities of turbulence, environment, sediment composition, etc., would be expected to cause local variations in the fossil assemblages,with even occasional heterogeneous combinations of sediments and fossils of a wide variety of shapes and siEes, 4ust as wefind in the complex geological record.8n any case, it needs to be emphasiEed that the socalled LtransitionalM fossil forms thatare true LintermediatesM in the strata se7uences between supposed ancestors and supposed descendants according to theevolutionary model are exceedingly rare, and are not found at all among the groups with the best fossil records shallowmarine invertebrates like mollusks and brachiopods$.// 8ndeed, even evolutionary researchers have found that thesuccessive fossil assemblages in the strata record invariably only show trivial differences between fossil organisms, thedifferent fossil groups with their distinctive body plans appearing abruptly in the record, and then essentially staying thesame stasis$ in the record./6

%eha/ior and -igher ,o0ility o the (erte0rates"here is another reason why it is totally reasonable to expect that vertebrates would be found fossiliEed higher in the

geologic record than the first invertebrates. 8ndeed, if vertebrates were to be ranked according to their likelihood of beingburied early in the fossil record, then we would expect oceanic fish to be buried first, since they live at the lowestelevation./2 However, in the ocean, the fish live in the water column and have great mobility, unlike the invertebrates thatlive on the ocean floor and have more restricted mobility, or are even attached to a substrate. "herefore, we would expectthe fish to only be buried and fossiliEed subse7uent to the first marine invertebrates.9f course, fish would have inhabitedwater at all different elevations in the prelood world, even up in mountain streams, as well as the lowland, swampyhabitats, but their ranking is based on where the first representatives of fish are likely to be buried. "hus it is hardlysurprising to find that the first vertebrates to be found in the fossil record, and then only sparingly, are in 9rdovician strata.&ubse7uently, fish fossils are found in profusion higher up in the +evonian strata, often in great Lfossil graveyards,Mindicating their violent burial.A second factor in the ranking of the likelihood of vertebrates being buried is how animals wouldreact to the lood. "he behavior of some animals is very rigid and stereotyped, so they prefer to stay where they are used toliving, and thus would have had little chance of escape. Adaptable animals would have recogniEed something was wrong,and thus made an effort to escape. ish are the least adaptable in their behavior, while amphibians come next, and then arefollowed by reptiles, birds, and lastly, the mammals."he third factor to be considered is the mobility of land vertebrates.

9nce they become aware of the need to escape, how capable would they then have been of running, swimming, flying, or even riding on floating debris Amphibians would have been the least mobile, with reptiles performing somewhat better, butnot being e7ual to the mammals? mobility, due largely to their low metabolic rates. However, birds, with their ability to fly,would have had the best expected mobility, even being able to find temporary refuge on floating debris."hese three factorswould tend to support each other. 8f they had worked against each other, then the order of vertebrates in the fossil recordwould be more difficult to explain. However, since they all do work together, it is realistic to suggest that the combination of these factors could have contributed significantly to producing the general se7uence we now observe in the fossil record.8ngeneral, therefore, the land animals and plants would be expected to have been caught somewhat later in the period of rising lood waters and buried in the sediments in much the same order as that found in the geologic record, asconventionally depicted in the standard geologic column. "hus, generally speaking, sediment beds burying marinevertebrates would be overlain by beds containing fossiliEed amphibians, then beds with reptile fossils, and, finally, bedscontaining fossils of birds and mammals. "his is essentially in the orderK8ncreasing mobility, and therefore increasing ability to postpone inundation and burialQ+ecreasing density and other hydrodynamic factors, which would tend to promote later burialQ and8ncreasing elevation of habitat and therefore time re7uired for the lood waters to rise and advance to overtake them.

"his order is essentially consistent with the implications account of the lood, and therefore it provides further circumstantialevidence of the veracity of that account. 9f course, there would have been many exceptions to this expected general order,both in terms of omissions and inversions, as the water currents waxed and waned, and their directions changed due toobstacles and obstructions as the land became increasingly submerged and more and more amphibians, reptiles, andmammals were overtaken by the waters.9ther factors must have been significant in influencing the time when many groupsof organisms met their demise. As the catastrophic destruction progressed, there would have been changes in the chemistryof seas and lakes from the mixing of fresh and salt water, and from contamination by leaching of other chemicals. #achspecies of a7uatic organism would have had its own physiological tolerance to these changes. "hus, there would have beena se7uence of mass mortalities of different groups as the water 7uality changed. Changes in the turbidity of the waters,pollution of the air by volcanic ash, andS or changes in air temperatures, would likely have had similar effects. &o whereasecological Eonation of the prelood world is a useful concept in explaining how the catastrophic processes during the loodwould have produced the order of fossils now seen in the geologic record, the reality was undoubtedly much more complex,due to many other factors.

Conclusions

8n no sense is it necessary to capitulate to the vociferous claim that the order in the fossil record is evidence of theprogressive organic evolution to today?s plants and animals through various transitional intermediary stages over millions of years from common ancestors. *hile there are underlying thick strata se7uences which are devoid of fossils and weretherefore formed during creation and the preflood era, most of the fossil record is a record of death and burial of animalsand plants during the flood, as described in the creation account, rather than being the order of a living succession thatsuffered the occasional mass extinction.Asteroid impacts and volcanic eruptions accompanied other geological processesthat catastrophically destroyed plants, animals, and people, and reshaped the earth?s surface during the lood event. !ather than re7uiring long ages, the order of fossils in the rock record can be accounted for by the yearlong lood, as a result of the prelood biogeography and ecological Eonation, the early burial of marine creatures, the hydrodynamic selectivity of moving water, and the behavior and higher mobility of the vertebrates. "hus, the order of the fossils in the rock recorddoesn?t favor long ages, but is consistent with the global, catastrophic, yearlong flood cataclysm, followed by localiEedresidual catastrophism.

"here is still the problem though of establishing a causal link between the microfossils found in fossil stromatolites and thebuilding of the stromatolites themselves. 8nstead of the associated fossil microbes being the builders of the fossilstromatolites that enclose them, it could be argued that the original microbes were trapped in the stromatolite structureswhen they were being built by abiotic sedimentary processes. )evertheless, the overall morphology shape and siEe$ of thestromatolites themselves, rather than 4ust their internal microstructures e.g. laminations$, can still be a useful criterion for establishing the biogenicity of fossil stromatolites. or example, *ise and &nelling 6@$ described a fossiliEed stromatolitereef in the )eoproteroEoic 3wagunt ormation of the eastern Grand Canyon, consisting of  in situ grown stromatolites sidebyside, and they concluded that these stromatolites were of biogenic origin.

roteroEoic stromatolites by microbial mat activity is not 7uestioned, due to the morphology of the stromatolites in their sedimentary contexts being comparatively similar to modern living stromatolites, even though today?s microbial matbuildersare often not identical to the fossil microbes sometimes found associated with the fossil stromatolites."hus the listed criteria are not individually diagnostic of the biogenicity of fossil stromatolites.

However, in the case of a given stromatolite all three could be true a created fossil core,an initially created living stromatolite structure, and subse7uent postcreation growth$. urthermore, the creation of a Lfullyfunctioning entityM would seem, almost by definition to have involved the creation of a fossil core and allowed for postcreation growth. "hese thus do not seem to be mutually exclusive possibilities.#ach of these options has its difficulties. 8s it reasonable to assume that Archean stromatolite reef would have been createdin fossil form 8f such a fossil stromatolites are already created in fossil form, logically it could be postulated that all thefossils are created as they are. *here then in the geologic record would the fossils have changed from those directlycreated , to those produced by living creatures being buried and fossiliEed Iet at some point this must seriously beconsidered as a possibility in the youngearth creationist model."he second logical possibility is that the stromatolites were created alive as fully functioning entities and then they wereburied subse7uently by ongoing sedimentary processes. However, given that above the earliest Archean 2.@ Ga$ fossilstromatolites in the *estern Australian +resser ormation there is a very thick and extensive recambrian rock se7uencethat also contains fossil stromatolites, including stromatolite reef structures spanning from other early Archean stromatolites

through to those in the )eoproteroEoic Allwood et al. 6J, 6BQ *ise < &nelling 6@$, at what point in this strata record,the first fully functional living stromatolites were created 8f only the earliest fossil stromatolites are created , those in thelower Archean rock units, then it might be argued that all those fossil stromatolites in the overlying rock units in these thickrecambrian rock se7uences would have to have formed by LnormalM secondary natural$ processes, which would seem tore7uire an enormous timespan. "hen again, there is the likelihood that some or even many$ of those overlying sedimentswere formed by reworking of previous sediments, and thus the stromatolites could similarly be reworked."he third logical possibility is that the matbuilding microbes were only created , and they then built the first stromatolites thatwere then buried and fossiliEed in the +resser ormation. "his possibility is only a small modification of the secondpossibility 4ust discussed, with a small step back in time to be created 4ust the matbuilding microbes rather than thecomplete stromatolites in a fully functioning reef. "his possibility then re7uires an enormous timespan for all the subse7uentstromatolites and stromatolite reefs fossiliEed in the thick overlying recambrian rock se7uences to grow and then be buriedand fossiliEed, andSor be reworked."he choice between these options therefore would seem somewhat arbitrary, since a case could be argued for each. %ut thedifficulty of deciphering at what point in the fossil record is the boundary between the created fossils and then the fossils

which formed from creatures that lived and were subse7uently buried would seem to rule out the first option. &ince thesecond and third options are closely similar, a fully developed completed entities are created that appear to have beenproduced according to human experience$ by secondary processes ,then it might be considered reasonable to start with theworking hypothesis that the first stromatolites are created as fully functioning living entities. "his also makes good sense, inthat when the soil were created on the land surface the microbes would have also be created in the soil that are part of thatfully functioning ecosystem i.e. as part of the entity they are created in$.8n the creation geologic model of earth history proposed by &nelling 60$ it is postulated that the earliest rocks of thegeologic record were created and put in place along with the earth?s fundamental internal structure. *e are not told whatwas under those globecovering waters of those first two days, so we can propose the possibility of the first rocks makingthe earth?s earliest crust, which may have even included marine sediments covering a crystalline basement. (nder a globalocean today one would expect marine sediments covering the ocean floor, and in shallower areas these sediments would becarbonates, even containing microbes. &o if fully functioning entities were created then it is reasonable to postulate that thefirst fully functioning stromatolites could have been created with matbuilding microbes, 7uite likely even includingstromatolite reefs, with the sediments blanketing the global ocean floor. "his is consistent with creating creating soilmicrobes in the soils .8f the gathering of the waters covering the earth into one place and formed the dry land, such actions re7uired catastrophicearth movements to create and uplift a supercontinent. As the supercontinent breached the global ocean, the waterscovering the emerging supercontinent were swept aside, and as they drained away they catastrophically eroded thatemerging land surface. "he sediments carried by those retreating waters in this LGreat !egressionM would have beendeposited at the margins of the supercontinent, with diminishing 7uantities being spread thinly over the ocean floors aroundthe rest of the globe. &ince the emerging land surface would have originally been ocean floor covered in sediments,including carbonates with stromatolites and stromatolite reefs, then these would also have been eroded and reworked. *e

may thus con4ecture the possibility of continued catastrophic deposition from the retreating sedimentladen waters of theGreat !egression beyond the continental margins through the the early part of the prelood era. &uch catastrophicdeposition would accomplish the rapid accumulation of the thick Archean to midroteroEoic sedimentary strata se7uences,including entombed stromatolites and microbes, before 7uieter conditions prevailed offshore, where renewed growth of stromatolites and stromatolite reefs began again as matbuilding microbes reestablished themselves on and in the shallowoffshore carbonate sediments."his implies that the immense thick se7uences of recambrian sediments enclosing many repeated levels in whichstromatolites are found fossiliEed over wide geographic areas can be fitted into the time period from the creation throughthe /J@ or so years of the prelood era. "his re7uires mechanisms for both the accumulation of those thick recambriansedimentary strata se7uences enclosing and fossiliEing many stromatolites, microbes and stromatolite reefs reworked fromthose created prior to the !egression growing in and on the carbonate sediments of the first global ocean floor, and then for subse7uent penecontemporaneous and synchronous growth of stromatolites, microbes and stromatolite reefs in the 7uieter 

prelood era offshore conditions, some also being buried and fossiliEed as prelood sedimentation continued."his proposed scenario then raises the 7uestion as to where in the geologic record the prelood era boundary might beplaced. "he ArcheanroteroEoic geologic record preserves evidence of the activities of those springs and fountains&nelling 60$. 8f these springs and fountains were initiated by the catastrophic earth movements when the uplifted prelood supercontinent formed and these waters were therefore initially very hot from the magmatic activity associated withthose earth movements, then this would be reflected in the geologic record accumulated in this dynamic period through thelatter part of the creation. "hat the waters of these fountains and springs were hot and therefore mineralladen is evidencedby the uni7uely roteroEoic, massive banded iron formations %8s$, volcanic and volcaniclastic strata, and the thickcarbonate sedimentary units with their enclosed fossil stromatolites. &ince these %8s are uni7ue to this section of thegeologic record &nelling 60$, it could be argued that they represent a uni7ue period in earth?s history. And since their arguably rapid accumulation was accompanied by massive outpourings of volcanics and explosive volcaniclastics, it may befeasible to e7uate these and the %8s as having accumulated rapidly during the dynamic period of the Great !egression andits aftermath through the remainder of the creation. "his would then place the creationpreflood era boundary some place inthe geologic record above these %8s, perhaps even as high as the aleoproteroEoicFesoproteroEoic boundary /.J Ga$

Gradstein et al. 6/6$.*ise 62$ proposed that there were extensive fringing stromatolite reefs around the prelood supercontinent. "he reeftoland LlagoonM was probably at least hundreds of kilometers wide, based upon the distribution of the extensive carbonateplatforms on which carbonate sedimentary units accumulated during the recambrian. "hese stromatolite reefs constituteda stromatolitehydrothermal biome that only flourished in the prelood era. "he hot waters of the fountains and springs notonly provided the nutrients for the rapid growth of the microbes responsible for building these fringing stromatolite reefs andthe associated stromatolites that grew within the enclosed shallow lagoon waters, but also the voluminous dissolvedminerals that were precipitated to accumulate the thick carbonate sedimentary units that entombed and fossiliEed thestromatolites. "he )eoproteroEoic 3wagunt ormation stromatolite reef described by *ise and &nelling 6@$ would be thefossiliEed remains of an example of this prelood stromatolitehydrothermal biome."he breakup of the prelood supercontinent during the terminal )eoproteroEoic at the initiation of the lood would thenhave marked the almost complete demise of living stromatolites. "he lood cataclysm began with the breaking up of thosefountains of the great deep, the collapse of the margins of the prelood supercontinent, and the rifting of the supercontinentand the ocean basins. "he lood cataclysm then reshaped the earth?s surface as it deposited the haneroEoic geologicrecord and entombed macrofossils in it. +uring the catastrophic conditions of the yearlong lood there were not sufficiently

long timespans available for microbial activity on transient surfaces to develop into living and growing stromatolites of anysignificant thickness or geographic extent. "his would explain the almost complete lack of fossil stromatolites of anysignificant thickness or geographic extent in the aleoEoicFesoEoic strata record of the lood catastrophe. "he microbeswhich survived through the lood then reestablished their matbuilding activities to again grow stromatolites during thewaning stages of the lood through to the present, as seen in the uppermost part of the haneroEoic strata and fossilrecords. 8n the present world living stromatolite remnants are rare and geographically isolated.Conclusion"oday?s rare stromatolites are being built by the metabolism of bacterial microbes in mat communities at the sedimentsurfacewater interface in a few geographically isolated locations. Growth is by sediment grain trapping and bindingprincipally by precipitation of calcium carbonate, resulting in a distinctive cyclical laminar microstructure as the microbialmats repeatedly reestablish themselves at the sedimentwater interface. "his laminar microstructure and the matbuildingmicrobes are the distinctive features of living stromatolites that are essential criteria in determining whether the relativelyabundant ArcheanroteroEoic conventionally 2@5@>/ Fa$ fossil stromatolites are likewise of biogenic origin. A robust setof biogenicity criteria have been established, which include the identification of microbial fossils associated with fossil

stromatolites that should be composed of kerogen and have an appropriate carbon isotope signature. owerful diagnostictechni7ues that can establish the identity of genuine microfossils have thus confirmed the biogenicity of many genuine fossilstromatolites, and even stromatolitic reefs, as far back in the strata record as the lower Archean conventionally dated asearly as 2>0J Fa$.*ithin the creation framework of earth history microbes, fully functioning stromatolites and even stromatolite reefs may havebeen created, as an integral component of the carbonate sediments on the floor of the global ocean. +uring the Great!egression those carbonate sediments, stromatolites and stromatolite reefs could have then been eroded and reworked tobe deposited in subse7uent sedimentary rock layers, thus accounting for their occurrence in the thick recambrianse7uences. 9nce reestablished in the prelood era, matbuilding microbes and stromatolites then flourished in reefsfringing the prelood supercontinent and in the wide lagoons they enclosed, first as sediments were rapidly deposited off the prelood supercontinent?s margins after the land emerged, and then continuing on through the prelood era. "heir rapid proliferation was facilitated by the mineralladen hot waters from fountains and springs, which also precipitated thestromatolitefossiliEing extensive thick carbonate strata. "he onset of the lood cataclysm marked the demise of livingstromatolites. (nable to establish themselves and grow during the devastation of the lood, today?s rare stromatolites arestill being built by those matbuilding microbes that survived in a few isolated places with conditions suitable for their growth.

 At the top of all these rocks, running the length of the whole canyon, is a prominent erosion surface, where the lood watersviolently eroded all preexisting prelood$ rocks, as the water rose up from the oceans to advance over thecontinents.J  Above this erosion surface is the "apeats &andstone, which represents one of the earliest layers of sedimentdeposited by the lood.

"his is exactly what we find, including this fossil recordwithin the Grand CanyonDGrand &taircase.Iou can also see another interesting pattern that confirms what we would expect from a global lood.

"his laboratory uses the more sensitive accelerator mass spectrometry AF&$ techni7ue,recogniEed as producing the most reliable radiocarbon results, even on minute 7uantities of carbon in samples."he laboratory staff were not told exactly where the fossil wood came from, or its supposed evolutionary age, to ensurethere would be no resultant bias. ollowing routine lab procedure, the sample their lab code G562J>>$ was treated firstwith hot dilute hydrochloric acid to remove any carbonates, and then with hot dilute caustic soda to remove any humic acidsor other organic contaminants. After washing and drying, it was combusted to recover any carbon dioxide for theradiocarbon analysis."he analytical report from the laboratory indicated detectable radiocarbon had been found in the fossil wood, yielding a

 Anticipating ob4ections that the minute 7uantity of detected radiocarbon in this fossil wood might still be due tocontamination, the 7uestion of contamination by recent microbial and fungal activity, long after the wood was buried, wasraised with the staff at this, and another, radiocarbon laboratory. %oth labs unhesitatingly replied that there would be no suchcontamination problem.

Conclusions"he evidence, both from scientists' laboratories and the natural laboratory, shows that under the right chemical conditionswood can be rapidly petrified by silicification, even at normal temperatures and pressures. "he process of petrification of wood is now so well known and understood that scientists can rapidly make petrified wood in their laboratories at will.(nfortunately, most people still think, and are led to believe, that fossiliEed wood buried in rock strata must have takenthousands, if not millions, of years to petrify. Clearly, such thinking is erroneous, since it has been repeatedly demonstratedthat petrification of wood can, and does, occur rapidly. "hus the timeframe for the formation of the petrified wood within thegeological record is totally compatible with the creation timescale of a recent creation and a subse7uent devastating global

"hus they concluded that

"hey also asked, rhetoricallyKN*as this animal secondarily a7uatic, or do the fishlike characters indicate retention of the primitive condition *ere itstetrapodlike characters = evolved among more terrestrial tetrapods, or were they originally developed for life in shallow,swampy waters?6/

Clearly, in their minds, and the minds of their fellow evolutionary palaeontologists, this mosaic of fish and tetrapodlikecharacters, and the presumed mode of life, make  ,canthostega a Nmissing link?, even though they describe it as a tetrapod,that is, a fourlegged animal. However,  ,canthostega was a fully formed and fully functional fourlegged amphibian, with four legs and not four fins, in some respects not unlike amphibians such as salamanders and newts.Fosaics don?t count"heir description of   ,canthostega as a Nmosaic? is significant.  ,canthostegais not the first fossil to be called a mosaic, acreature that has characteristics common to two or more other types of creatures. or example, Australia?s platypus has milkglands and fur that classify it as a mammal, but it has a leathery egg, echolocation ability, a duckbill, webbed feet, poison

spurs and other features that it shares in common with other animals, not only mammals.ike ,canthostega,  ,rchaeoptery4  has been regarded as an evolutionary intermediate Nmissing link?$, but leadingevolutionists Gould and #ldredge state thatN&mooth intermediates = are almost impossible to construct, even in thought experimentsQ there is certainly no evidence for them in the fossil record curious mosaics like  ,rchaeoptery4  do not count$.?66

8n other words, fossils such as  ,canthostega are regarded by some evolutionary palaeontologists as Nmissing links? notbecause they are, but because they are believed to be.

Conclusion"he fossil record has so far revealed many types of fish, some of which have bones in their fin lobes, serving a usefulpurpose as in the coelacanth long believed to be an extinct ancestor of land animals, until it was found alive and well$. "hefossil record has also revealed many types of amphibians, including 5chthyostega and  ,canthostega, in which the limbbones are firmly attached to the backbone and clearly designed for bearing the weight of the body in walking. Anything trulyNinbetween? these crucial fish and amphibian characters is not only hard to conceive, but has never been found.

2here Are All the -uman &ossils5by +r. Andrew A. &nelling on +ecember /, /00/

'riginally published in Creation !$* no ! +Fecember !--!/ ")0##.&hop )ow"here are some claims and reports of human artefacts and remains in rock layers that are clearly part of the floodsediments. However, many of these claims are not ade7uately documented in any scientific sense, while those few reportsthat have appeared in the scientific and related literature remain open to 7uestion or other interpretations. or example, thebook  ,ncient Man/ , andbook of 8uling ,rtifacts/ looks like an impressive and voluminous collection of such evidence,but on closer examination many of the artefacts, though puEEling archaeologically, still belong to the postflood era, whileother reports and claims are either anti7uated or sketchy and amateurish.9ften lay scientists claiming to have found human artefacts or fossils have not recorded specific location details, so thatprofessional scientists investigating the claims have had difficulty finding the location from which the sample in 7uestioncame. A&9, lay scientists have in the past not kept some of the rock which encloses the fossil or artefact as proof of its  insitu occurrence. "hese two oversights have often made it well nigh impossible to reconstruct andSor prove where fossils or 

artefacts came from, thus rendering such finds virtually useless.ossiliEed hammers and supposed human footprints in ancient geological strata, regarded by evolutionists as depositedmillions of years before man evolved, but regarded by creationists as flood deposits, are extremely difficult to documentscientifically above reproach andSor with any conclusive finality. Ferely finding rock around an implement does not prove itis preflood.$or example, it has been claimed that a gold chain was found in black coal. 6 However, the artefact evidently was exhibitedas a clean gold chain with no coal clinging to it, so we see no evidence that the chain was actually found in the coal, 4ust theclaim that it was. *hile one would never assume any dishonesty on the part of the people concerned, because proper scientific procedures have not been followed the exhibit has proven to be almost useless in convincing a generally skepticalscientific community and apathetic lay public."hus, should genuine human fossils or artefacts from the time of the global flood be found, then it is mandatory that proper scientific procedures be followed to document the geological context, in order to guarantee that the scientific significance of such a find is une7uivocally demonstrated. !egretfully, of course, the hardened skeptic would still remain unconvinced, butat least such a find may still awaken some in the apathetic public and a few of the more openminded scientists.*hat is needed, of course, are actual human bones fossiliEed in situ as an integral part of rock strata that are demonstrably

ancient in evolutionary terms, and therefore are usually flood sediments of the creationist framework for earth history. Iethere is where the real hard une7uivocal evidence is lacking and why people ask the 7uestion L*here are all the humanfossilsM*e simply cannot point to the report of a human skull found in socalled "ertiary brown coal in Germany, for there is nodefinitive scientific report available on this ob4ect, even though its existence has been verified by the staff of the Fining

 Academy in reiberg.2 8f it is a coalified human skull, how is it possible to distinguish it from a clever carving in such a waythat it becomes conclusive proof #ven if it were demonstrated as genuine, are we sure that the "ertiary brown coal in7uestion was a flood stratum 8n some parts of the world some of the isolated socalled "ertiary sedimentary basins couldeasily be classified, according to some creationist geological schemes, as postflood strata. After all, the early floodgeologists, prior to the advent of yellian uniformitarianism and the evolutionary geological timescale, applied the termL"ertiaryM to those rock strata that they believed to be postflood."he controversial Guadeloupe skeletons are another case in point.> *ithout wishing to take sides in the debate, and in anycase the hard data are still inconclusive either way, the fact remains that even if perchance these skeletons were socalledFiocene, that in and of itself would still not prove that the skeletons were in flood sediments and therefore represented the

remains of preflood people. %eing a subdivision of the socalled "ertiary, these Fiocene rocks may still be postfloodsediments and so these Guadeloupe skeletons may still not be human fossils from the global flood.erhaps the fossiliEed human skeletons that come closest to having been preflood humans buried in flood strata are thoseskeletons found at Foab, (tah (&A$.@ 8n a copper mine there, two definitely human skeletons were found in CretaceousLageMQ sandstone supposedly more than J@ million years old$, the bones still 4oined together naturally and stained greenwith copper carbonate. *hile many regard these bones as recently buried, there still remains the remote possibility that theyare preflood human Lfossils.M*e can only concur that there is no definite une7uivocal evidence of human remains in those rock strata that can definitelybe identified as flood sediments. "his realiEation is at first rather perplexing. %ut some clues to unravelling this puEEleemerge on investigation.The Nature o the &ossil Recordet?s begin by considering the nature of the fossil record. Fost people don?t realiEe that in terms of numbers of fossils 0@Wof the fossil record consists of shallow marine organisms such as corals and shellfish.J *ithin the remaining @W, 0@W areall the algae and plantStree fossils, including the vegetation that now makes up the trillions of tonnes of coal, and all the other invertebrate fossils including the insects.

8n any regional area where vertebrate fossils are found, there is a general tendency for these land animals to be higher up inthe rock strata se7uence on top of the strata containing marine organisms. "his has been interpreted by evolutionists asrepresenting the evolutionary se7uence of life from marine invertebrates through fish and amphibians to the landbasedvertebrates.However, this same observation can be more reasonably explained by flood geologists as due to the order of burial of thedifferent ecological Eones of organisms by the flood waters. or example, shallow marine organismsS ecological Eoneswould be the first destroyed by the fountains of the great deep breaking open, with the erosional runoff from the land due tothe torrential rainfall concurrently burying them. 9n this basis then we would probably not expect to find human remains inthe early flood strata, which would contain only shallow marine organisms. "he fossil record as we understand it at themoment certainly fits with this.

 Additionally, the ma4ority of the few mammal fossils in the fossil record are in the socalled "ertiary strata, which mostcreationist geologists nowadays regard as postflood strata. 8f this is the case, then there really aren?t very many mammal

fossils in the late lood sediments there are a few mammal fossils in the socalled FesoEoic rocks$. Conse7uently, it?s notonly human fossils that are not found in the lood sediments, but there is a relative lack of other mammal fossils also.9f course, in the postlood era humans would have been able to make the necessary decisions to get away from the localresidual catastrophes responsible for the postlood "ertiary$ strata, so we wouldn?t expect to find humans fossiliEed inpostlood sediments like we find other mammals.

 Another problem in the fossil record is, as we have already seen, the fragmentary nature of what is often found, whichmakes identification difficult. or example,?a five million yearold piece of bone that was thought to be the collarbone of ahuman like creature is actually part of a dolphin rib . . .? 0 &uch genuine mistakes are inevitable when only fragments of boneare recovered from the rocks. *e can?t even be sure that some bone fragments already found in lood sediments aren?t infact human remains, having been labelled something else by evolutionists. After all, because of their evolutionarymoleculestoman belief bias$ they don?t expect to find human remains in lower older$ strata.Dierential ,o0ility

 Another factor to be considered is the differential mobility of humans and many landdwelling animals compared to much of the abundant marine life, such as corals, barnacles and shellfish. *hen the lood began, the rising lood waters would

probably have encouraged humans and mobile land animals to preferentially move away from low lying areas to higher ground. "hus their being swept away by the lood waters would probably have been postponed perhaps for weeks$ until allthe high ground also was covered.Conse7uently, we would predict that it would be highly unlikely for us to find human fossils now in sediments that weredeposited early in the lood year. 8ndeed, when we look at the fossil record, as we have already seen, we find that in the socalled aleoEoic strata there is a preponderance of marine creatures, beginning with trilobites, corals, sea anemones,shellfish of all types, etc. "his is what we would predict, given that the lood waters carried sediments from the land out tothe sea where they would then be deposited, burying many of the relatively immobile seafloordwelling creatures, followedlater by destruction and burial of fish. "hus it is not surprising that we see the landdwelling animals being preserved later inthe fossil record, where they would have been buried later in the lood year as the rising lood waters finally covered theland surface completely.Destruction o Skeletons"he next 7uestion to ask isK *ould all the people still be alive when the lood waters finally covered all the land and sweptthem away to be buried and preserved as fossils in the later lood sediments Can we assume that there was nodestruction of the people?s bodies in the lood waters and by other processes operating during the lood and subse7uently

robably notO"he turbulence of the water, even in a local flood, can be horrific, particularly when the fastmoving current picks up not onlysand and mud, but large boulders. (nder such conditions, human bodies would probably be thrown around like flotsam andwould tend to be destroyed by the agitation and abrasion.%ut even if human bodies were buried in the later lood sediments, destruction could still occur subse7uently that is, postdeposition$. or example, if ground waters permeating through the sediments such as sandstone$ contain sufficient oxygen,then the oxygen would probably oxidiEe the organic molecules in the buried bodies and so destroy them. "his could beregarded as a type of weathering.$ ikewise, chemically active ground waters could also be capable of dissolving humanbones, removing all trace of buried people.Fany lood sediments have also undergone chemical and mineralogical changes due to the temperatures and pressures of burial, plus the presence of the water trapped in between the sediment grains. "his process of change, known technically asmetamorphism, eventually obliterates many fossils in the original sediments, whether they be fossils of shellfish, corals or mammals, particularly with increasing depth of burial, and higher temperatures and pressures.Iet another process that could destroy buried human bodies would be the intrusion of molten igneous$ rock into the lood

sediments, and through them to the surface to form volcanoes and lava flows. &uch processes involve heat intense enoughto melt rocks and recrystalliEe them. As the hot molten rock rises through the sediments, the sediments are often baked bythe heat, and again chemical and mineralogical changes occur that obliterate many contained fossils. All of these factorsgreatly lengthen the odds of finding a human fossil today.Dierential Sus"ension)ot only would the turbulence of the sedimentladen lood waters probably destroy some of the human bodies swept away,but differential suspension in the waters could have made it hard to bury those bodies that survived the turbulence. "his isbecause human bodies when immersed in water tend to bloat, and therefore become lighter and float to the surface. "his iswhat is meant by differential suspension. "he human bodies floating on the water surface could therefore for some time becarrion for whatever birds were still flying around seeking places to land and food to eat. ikewise, marine carnivores stillalive in their watery habitat would also devour corpses.urthermore, if the bodies floated long enough and were not eaten as carrion, then they would still have tended to either decompose or be battered to destruction on and in the waters before any burial could take place. "his could explain why westill don?t find human fossils higher up in the fossil recordSgeological column, that is, the later lood sediments.*hen we take all these factors into account, it would seem unlikely that many of the people present at the time the loodwaters came could have ended up being fossiliEed. #ven if a handful, perhaps a few thousand, were preserved, when sucha small number is distributed through the vast volume of lood sediments, the chances of one being found at the surfaceare mathematically very, very low, let alone of being found by a professional scientist who could recogniEe its significanceand document it properly.utting all these factors together and assuming that they are all realistic possibilities, then the probability of finding a humanfossil in the lood sediments today would be very, very small. "o date, our investigations of the fossil record indicate thatthere are no human fossils in lood strata, so perhaps the above explanations could be some of the reasons why this is so.

Conclusions As far as we are aware at the present time, there are no indisputable human fossils in the fossil record that we could saybelong to the prelood human cultures$. *hen we endeavour to understand some of the processes that may haveoccurred during the lood, and also the real nature of the fossil record, we are not embarrassed by the seeming lack of human fossils.*e don?t have all the explanations as to how the evidence came to be that way, and it may be that in the future we willdiscover some human fossils. However, there is also much about the fossil record that the evolutionists have a hard timeexplaining. 9n the other hand, we should also realiEe that we don?t have all the answers either, and we never will.%ecause we weren?t there at the time of the lood we cannot scientifically prove exactly what happened, so there will alwaysbe aspects that will involve our faith. However, it is not blind faith. As we have investigated the evidence, we have seennothing to contradict about a world lood. *e can be satisfied that there are reasonable explanations, for the seeming lackof human fossils in lood rocks.

Hence

at least 22 loods are needed, staggered in time, to generate our known coal beds. "herefore a single lood cannot be thecause of coal formation."his argument is based on valid estimates of the volume of vegetation currently on today?s landsurfaces. %ut it assumes that at least /6 metres of vegetation are needed to produce one metre of coal eg. Holmes, /0J@$.Fodern research shows that less than two metres of vegetation are needed to make one metre of coal. &ome observationsmade by coal geologists working in mines e.g. the compaction of coal around clay Nballs? included in some coal beds$suggest that the compaction ratio is probably much less than 6K/ and more likely very close to /K/.

Clays, coals and volcanism"he significance of the work of Hayatsu et al .6/ is in the role of clays as catalysts since the clay minerals illite,montmorillonite, and kaolinite are the most common inorganic mineral constituents of coals. 8n fact, clays often account for up to JW or 1W of the total mineral matter associated with the plant debris in coal.

 Another interesting observation on clays in coal is the differing percentages of clay in the different types of coal &ee "able2$. *hile fusains and durains normally contain a far greater percentage of mineral matter than vitrains and clarains, themineral content of vitrains is almost totally clay. urthermore, in most &outhern Hemisphere coals, clays predominate over other types of inorganic matter e.g. see *ard6>$. 8n Australian coals even after washing over half the original clay content

is still present, indicating that the clay is therefore homogeneouslydistributed throughout the coal.

igure !!. "he effect of rising temperatures during metamorphism of the clay minerals usually found in coal seams +ata from &tach  et al .6$.)ow these clays are also commonly derived from volcanic ash. "hesame clay minerals, principally kaolinite,6> can be found in the form of tonsteins which because of their widespread nature, have become

increasingly important as marker beds in coal measure sediments.&uch tonsteins are not only important as marker horiEons for particular bands in a single coal seam, but for seam correlation in a coal basin or district, and even in ad4acent coal basins over distances of severalhundred kilometres as has been experienced in )orthern #uropeancoal belts.6 8t has been suggested that these tonsteins originated asvolcanic ash falls./,//,6@"he presence of the clays, particularly kaolinite, also indicates that the

temperatures involved in coalification must have been less than 6VC. At and above this temperature the common clayminerals are metamorphosed, e.g. kaolinite to pyrophyllite see ig. //$. "his underlines the reasoning behind Hayatsu  et al.?s investigation of claycatalyEed coalification at low temperatures.6/"he weight of evidence observation and data$suggests that the clays found in coals and interseam sediments are involved in the coalification reactions and are importantindicators of the conditions during both seam deposition and seam coalification. "he clays strongly suggest related nearbyvolcanism and disallow cold climate swamp and peatforming environments as precursors to the coals.

Clays and "eat swam"s"he widespread presence of clays in coals has led advocates of the peat swamp hypothesis to suggest that the clays arederived from clays and feldspar debris washed into swamps during flood periods. However this suggestion ignores theobservation that in most acid swamp environments, clays will flocculate and not settle to the bottom. &uch a suspendedstate will not produce the homogenous distribution of clays throughout the organic swamp debris and it most definitelycannot explain the clay bands consistently traceable as marker horiEons between ad4acent coal basins.%ut it is still necessary to account for the current coal structures with their homogeneously distributed clays, particularlythrough the higher rank coals, so can this have been achieved by chemical means, that is, by precipitation from incomingsurface waters, percolating ground waters, or the swamp waters themselves *ard,6> for example, proposes severalmechanisms whereby the clay minerals could have been transported in solution as colloids, or as silica and alumina gels, tothen precipitate and crystalliEe within the structures of the coalforming peat, but he then admits that this mechanism doesnot explain some of the field and mineralogical evidence. "he inability of clay minerals to form within coals by suchmechanisms and under such conditions is dramatically illustrated by the presence of very pure, high grade clays associatedwith brown coal deposits and yet 7uite distinct from them. or example, the atrobe -alley brown coal seams at Iallourn andForewell, -ictoria, Australia, sit on pure white clay which has not Ndiffused? into the coal seams above or below them by such

groundwater action.6J "his is further confirmed by the virtual absence of aluminium silicates throughout the brown coal .6Binally, Fartini and Glooschenko2 and Fartini61 have shown and stated emphatically that cold climate peat swamps do nothave clay minerals in them. "his conclusively indicates that such environments are not suitable choices for precursors of coal seams.Discussion"he application of these data on the relationship between clays and coal indicates that the variables associated withcoalification should probably be expanded to include at leastK/$ "he presence of the appropriate clay minerals to act as catalystsQ6$ "he presence of the appropriate trace elements,2$ "he absence of catalytic poisonsQ>$ "he relevant pHQ@$ A rapid heat source of less than 6VCQ andJ$ A variable pressure source similar to that associated with volcanism or tectonism."his combination of variables successfully explains why nonanthracite coals are sometimes found in high grade

metamorphic rocks, showing that neither continuously applied pressure nor heat have been the key factors. &imilarly, it alsoexplains why some massive coal deposits are found as thick seams of low rank brown coal and not as more mature higher rank black coals. 9ne missing Ningredient? in these brown coals is aluminium silicates clays$. A classic case is the atrobe-alley coals at Iallourn in -ictoria, where thick brown coal seams are virtually devoid of clays. 6J,6B %y comparison, the thinower and (pper ilot &eams at )ewcastle consist of higher rank black coals containing abundant clays."his importantrelationship between clays and coalification also suggests why the various coal types are associated with different claycombinations even within the one seam, where temperature, pressure and pH had a high probability of being the same. or example, vitrain has low mineral matter but a large percentage of this mineral matter is clay, whereas fusain has highmineral matter but a much lesser percentage of its mineral matter is clay. "his higher mineral matter in fusain may well actas a coalification inhibitor or catalytic poison$."his same clayScoalification relationship can be taken a step further andapplied even to individual coalification events, such as that responsible for partial coalification of the tree stumps in the ilot&eams at )ewcastle. )ear the bases of these tree stumps where the pH was lower due to the abundant ad4acent vegetationdebris, coalification has occurred. Higher up the stumps where there was much less ad4acent vegetable material and higher amounts of siliceous volcanic ash, silicification has occurred. urthermore, at the bases of the tree stumps the ashsurrounds the outside of the stumps, so coalification of the ligninrich bark has occurred, whereas solution replacementoccurred internally with the woody tissues being replaced by iron carbonate. "he coalification of only the bark near thebases of these tree stumps can now be best explained as due to the thinner bark on the upper parts of the stumps havingbeen removed either by bacterial action similar to that seen in &pirit ake, or during the directed volcanic blast.ikewise, thecondition of the log found at 9akleigh can be explained on the assumption that it has been sub4ect to brief and thereforerapid$ claycatalyEed thermal activity around its circumference to produce high rank black coal, while the protected inner portion of the log remained virtually unaltered. "his thesis would also explain why the Awaba tree stumps and logs, whichare virtually devoid of accompanying vegetation debris, have been silicified rather than coalified, whereas the tree stumps

sitting on the ilot &eams have been coalified near their bases because of the accompanying acidgenerating vegetablematerial. 8f this thesis is correct, it is therefore feasible to predict that tree stumps and logs deposited in tuffaceoussediments devoid of accumulated acidgenerating vegetation debris will most probably petrify. "hus it is predicted thatshould appropriate conditions ensue the logs in the "outle Canyon ash flows will be more likely to petrify, while the logsbeing buried beneath the waters of &pirit ake will probably coalify around their external margins.8t should be obvious nowthat the explosive pyroclastic volcanism model can not only be applied to the deposition of coal seams, but can be invokedto produce rapid coalification of the same coal seams. "he implication is that the whole process from pine forests to coalseams was both catastrophic and extremely rapid.

model for coal seam formation.*lo0al &lood"he relevance to the lood of this explosive pyroclastic volcanism model for the rapid destruction of whole forests,deposition of forest debris in seams, and coalification of these seams should by now be obvious.

Helens were isolated to 4ust a small region that is hardly comparable tothe extent measuring thousands of s7uare kilometres of many Australian coal basins, including the &ydney and ClarenceForeton %asins )ewcastle and *alloon Coal Feasures respectively$.

"hus the /01 Fount &t. Helens eruption provides a model that isable to explain similar apparent growth position tree stumps and logs in ancient coal deposits which are associated withtuffaceous andSor clayrich sediments. (pon this basis it has been concluded that the tree stumps and logs on top of the

(pper and ower ilot &eams and in the Awaba Nfossil forest? horiEon at )ewcastle did not grow in situ even though they arefound in apparent growth positions. "he presence of both clays and coalified pine bark, cuticles and debris throughout theassociated ilot &eams, and in the coal seams at 9akleigh, indicate that the coal in these areas are not the product of terminal pine forests on ancient swamps, since it would be impossible then to explain the pine bark, cuticles and debristhroughout the coal. "hus the vegetable debris in the coal seams does not appear to have grown  in situ. !ather, it musthave been washed into the depositional basins from the same forests that the catastrophically deposited pine trees werestripped from by the explosive volcanism. "he coal therefore is allochthonous, and not autochthonous.&uch rapidaccumulation of carbonrich sediments in areas of volcanism also implies the possibility of rapid seam formation. At9akleigh the discovery in tuffaceous sandstones above the coal seams of a broken log that has black coal around itscircumference and lining a clayfilled internal fracture, but only woody brown coal inside, provides compelling evidence thattemperature and pressure are not the key factors in coalification and that coalification must have been rapid in such avolcanic setting. "his widespread association of volcanic ash and ashrich sediments particularly the tuffs and kaoliniterichtonstein marker beds$ with coal seams full of allochthonous forest debris is an indication that widespread volcanism wasassociated with past coal seam formation, and provides evidence consistent with experimentally demonstrated rapid lowtemperature less than 6VC$ claycatalyEed coalification of such seams in contrast with the slow formation, slowcoalification autochthonous peat swamp hypothesis. "he absence of clay in many present day peat deposits is sufficient tothrow further doubt on the peat swamp hypothesis and should relegate such clayfree peats to be viewed merely as analternative state of preserved carbonrich material. &uch peat deposits are thus not related to coalOApplying this explosivepyroclastic volcanism model to the formation of coal deposits worldwide, it is entirely feasible that all of today?s coal seamswere formed by the volcanism, flooding, erosion, deposition, tectonism and hydrothermal activity during the global yearlonglood catastrophe and its aftermath.

 All the available evidence points to a recent catastrophic origin for the world?s vast oil deposits, from plant and other organicdebris, consistent with the creation account of earth history. -ast forests grew on land and water surfaces/B in the preloodworld, and the oceans teemed with diatoms and other tiny photosynthetic organisms. "hen during the global loodcataclysm, the forests were uprooted and swept away. Huge masses of plant debris were rapidly buried in what thusbecame coal beds, and organic matter generally was dispersed throughout the many catastrophically depositedsedimentary rock layers.

Many people today* including scientists* have the idea that oil and natural gas must take a long time to form* even millions of years.&uch is the strong mental bias that has been generated by the prevailing evolutionary mindset of the scientific community.However, laboratory research has shown that petroleum hydrocarbons oil and gas$ can be made from natural materials inshort timespans. &uch research is spurred on by the need to find a viable process by which man may be able to replenishhis dwindling stocks of li7uid hydrocarbons so vital to modern technology.&rom Sewage to Oil"he / Farch /010 edition of  3he ,ge newspaper Felbourne, Australia$ carried a report from *ashington (&A$ entitledN!esearchers convert sewage into oil?. "he report states that researchers from %atelle aboratories in !ichland, *ashington&tate, use no fancy biotechnology or electronics, but the process they have developed takes raw, untreated sewage andconverts it to usable oil. "heir recipe works by concentrating the sludge and digesting it with alkali. As the mixture is heatedunder pressure, the hot alkali attacks the sewage, converting the complex organic material, particularly cellulose, into the

longchain hydrocarbons of crude oil.However, the oil produced in their first experiments did not have the 7ualities neededfor commercial fuel oil. &o, the report says, in &eptember /01B %atelle 4oined forces with American uel and ower Corporation, a company specialiEing in blending and recycling oils. "ogether they have made the oil more Nfreeflowing?using an additive adapted from one developed to cut down friction in engines. A fuel has now been produced with almost thesame heating value as diesel fuel. "he process from sewage to oil takes only a day or twoO"he researchers are now buildinga pilot plant. As the report states, potential economic benefits of this new technology are tremendous, since the processproduces more energy than is consumed during normal sewage disposal, and the surplus energy products can be sold at aprofit. %onuses include an 1 percent reduction in waste volumes, and the eradication of poisonous pollutants such asinsecticides, herbicides and toxic metals that normally end up in sewage.9f course, one cannot claim that this is the way oilcould have been made naturally in the ground in a short time period. "he starting raw material is manmade and hot alkalidigesters don't occur naturally in the ground.Coal to Oil in 'a0oratory9f greater significance are laboratory experiments that have generated petroleum under conditions simulating thoseoccurring naturally in a sedimentary rock basin. %etween /0BB and /012, research experiments were performed at the

C&8!9 Commonwealth &cientific and 8ndustrial !esearch 9rganisation$ laboratories in &ydney Australia$. 8n their reports/,6 the researchers noted that others had attempted to duplicate under laboratory conditions geochemical reactionsthat lead to economic deposits of li7uid and gaseous hydrocarbons, but such experiments had only lasted for a few or several hundred days, and usually at constant temperatures. Conse7uently, the differences in timescale and other parameters between geological processes and laboratory experiments being so great meant that scientists generally7uestioned the relevance of such laboratory results. "hus, in their experiments, the C&8!9 scientists had tried to carefullysimulate in a laboratory under a longer time period, in this case six years, the conditions in a naturally subsiding sedimentaryrock basin."wo types of source rock were chosen for this studyDan oil shale torbanite$ from Glen +avis )ew &outh *ales,

 Australia$, and a brown coal lignite$ from oy Iang in the atrobe -alley -ictoria, Australia$. %oth these samples wereimportant in the Australian context, since both represent natural source rocks in sedimentary basins where oil and naturalgas have been naturally generated from such source rocks, and in the case of the %ass &trait oil and natural gas fields,sufficient 7uantities to sustain commercial production."hese two source rock samples were each split into six subsamples,and each subsample was individually sealed in a separate stainless steel tube. "he two sets of six stainless steel tubeswere then placed in an oven at /VC and the temperature increased by /VC each week, After @, /, /@, 6, 6@, and2 weeks that is, at maximum temperatures of /@VC, 6VC, 6@VC, 2VC, 2@VC, and >VC$, one stainless steel tubefrom each series was removed, cooled and opened. Any gas in each tube was sampled and analysed. !esidues in eachtube were extracted and treated with solvents to remove any oil, which was then analysed. "he solid remaining was alsoweighed, studied, and analysed.&our +ears to ,imic 6Nature3"he results are very illuminating. At less than 2VC, 2@ percent of the oil shale had been converted to a paraffinic crude oil.

 At 2@VC not only was generation of the oil complete, but Ncracking? of the oil had occurred extensively, with thermaldecomposition producing JW gas.8n the brown coal samples, however, during the first @ weeks of heating, gas mainly

maximum temperatures.2

 However, the researchers believe their series of experiments are the best attempts so far toduplicate natural, subsiding, sedimentary conditions. #xtensive conversion of organic matter to hydrocarbons has also beenachieved at less than 2VC under noncatalytic conditions with a minimum of water present.urthermore, the researchers maintained that their experiments clearly show that altering the timescale of source rockheating from seconds the duration of many previous laboratory experiments$ to years makes the products produced similar to natural petroleum.They went on to say=8n many geological situations much longer time intervals are available but evidently the molecular mechanism of thedecomposition is little changed by the additional time. "hus, within sedimentary basins, heating times of several years aresufficient for the generation of oil and gas from suitable precursors. "he precise point in this range of times from seconds toyears, at which the products ade7uately resemble natural gases andSor oils, remains to be established. Heating times of theorder of years during recent times may even improve the petroleum prospects of particular areas. looding of a reservoir with migrating hydrocarbons is more likely to produce a reservoir filled to the spill point than slow accumulation over a longgeological period with a possibility of loss =?.>

"hey also noted that it should be remembered their experiments Nrelate to a situation which is possibly unusual in thegeological contextDone in which hydrocarbons do not migrate away from their source rocks as they are generated.? @

 Along these fractures through the sediments in the basin flows boiling hotwater at temperatures above 6VC, the result of deepseated volcanicactivity below the basin. "hese hot waters hydrothermal fluids$ dischargingthrough the sediments on the ocean floor have been investigated by deepsea divers in minisubmarines."he hydrothermal activity on the ocean floor releases discrete oil globules up to /56 centimetres in diameter$, which aredischarged into hydrothermal the ocean water with the hydrothermalfluids.B+isturbance of the surface layers of the sediments on the oceanbottom also releases oil globules.Correct measurement of the oil flow rate atthese sites has so far not been feasible, but the in situ collection of oilglobules has shown that the gasSoil ratio is approximately @K/. argemounds of volcanic sinter solids coalesced by heating$ form via

"hus the organic matter content of these sinter deposits in the mounds approaches 6>W.1"hehydrothermal oil from the Guaymas %asin is similar to reservoir crudeoils.0 &elected hydrocarbon ratios of the vapour phase are similar to thoseof the gasoline fraction of typical crude oils, while the general distributionpattern of light volatile hydrocarbons resembles that of crude oils see "ableof analyses$ . "he elemental composition is within the normal ranges of typical crude oils, while contents of some of the significant organiccomponents, and their distribution, are well within the range of normal crude

oils. 9ther key analytical techni7ues on the oil give results that arecompatible with a predominantly bacterialSalgal origin of the organic matter that is the source of the oil and gas. /"his oil and gas has probably formedby the action of hydrothermal processes on the organic matter within the

diatomaceous ooEe layers in the basin. 9f crucial significance is the radiocarbon C /> $ dating of the oil. &amples haveyielded ages between >,6 and >,0 years, with uncertainties in the range @/0 years. // "hus, the timetemperatureconversion of the sedimentary organic matter to hydrothermal petroleum has taken place over a very short geological timescale less than @, years$ and has occurred under relatively mild temperature conditions.8t is significant also that thetemperature conditions in these hydrothermal fluids, of up to and exceeding 2/@ VC, are similar to the ideal temperatures for oil and gas generation in the previously described Australian laboratory experiments./6 igure 6a illustrates the oil generationsystem operating in the Guaymas %asin, while igure 6b shows how this process could be applied in a closed sedimentarybasin to the hydrothermal generation of typical oil and gas deposits.

Ra"id Oil &ormation"he generally accepted model of oil generation assumes longterm heating and maturing of the sedimentary organic matter 

in subsiding sedimentary basins. "he organic matter undergoes successive and gradual increases in alteration, leading to aprocess of continuous oil generation. "he oil subse7uently migrates to be trapped in suitable host rocks and structures."hismultistep oil formation process has a low efficiency and converts only a minor fraction of the original organic matter of thesediment to oil./2 "here is difficulty in balancing and timing an ade7uate degree of oil generation occurring at intermediatestages in the sedimentary basin, and ample fluid available for ade7uate transport migration$ of the oil.Althoughconsiderable progress in the understanding of this multistep oil formation mechanism has been achieved, there are stillproblems that need to be solved. &uch a slow multistep mechanism differs significantly from hydrothermal petroleumformation. )o evidence is so far available on the extent to which this alternative singlestep oil generation process hascontributed towards the origin of presently exploited oil reserves.8t is very significant that this naturally producedhydrothermal oil is identical to conventionally exploited crude oils, as are the oil and gas products from the Australianlaboratory experiments. )evertheless, hydrothermal oil formation provides an efficient singlestep mechanism for petroleum

generation, expulsion, and migration which could have a considerable impact onour understanding of petroleum formation mechanisms and eventually assist us intapping resources in new areas./>"hus the rapid formation of oil and gas is not only

feasible on the basis of carefully controlled laboratory experiments, but has nowbeen shown to occur naturally under geological conditions that have been commonin the past.&ignificantly, these short timescales are well within those proposed bycreation scientists for the generation of petroleum from organic matter in sedimentslaid down during the lood. &ubse7uently, the discovery of the hydrothermallyproduced petroleum on the ocean floor in the Guaymas %asin of the Gulf of California is even more crucial to the case of the creation scientists and loodgeologists, when they argue that the fountains of the deep referred to in the %ook of Genesis were probably vast volcanic upheavals that broke open the earth's crust,pulveriEing rock which was then scattered as volcanic debris, and expelling lavas,gases, and hot li7uids, principally water.8ndeed, the bulk of the volcanic productswould have been superheated water, similar to the hydrothermal fluids found in theGuaymas %asin. "he rock record contains many layers of volcanic lavas and ashbetween other sedimentary layers, many containing organic matter. "hus thismodel for hydrothermal generation of petroleum is more than a feasible process for the generation of today?s oil and gas deposits in the timescale subse7uent to thelood as suggested by creation scientists.
