Geologic Report of Howard County, Arkansas

Introduction

Howard County is located in

southwestern Arkansas (Fig. 1), has a

population estimated to be 13,789 and an

area of approximately 587.42 square miles

(US Census data 2010). The county lies

between latitude coordinates 34.360o and

33.740o, and longitude coordinates -93.830o

and -94.261o (Plate 1). The highest

elevation in the county is about 1660 ft. (506

m) above sea level, and occurs on Big Tom

Mountain in the northeastern part of the

county (Athens 7.5 min. quadrangle). The

lowest elevation is approximately 255 ft. (78

m) above sea level, at the confluence of

Mine Creek and Lake Millwood (Mineral

Springs South 7.5 min. quadrangle). Major

surface drainages include the Saline and

Cossatot rivers, Mine and Harris creeks,

and Sulphur Slough - which flow north to

south - and Muddy Fork, which flows west

to east.

Figure 1: Location of Howard County. Also shown are the physiographic provinces of Arkansas

Howard County straddles two

physiographic provinces: the Ouachita

Mountains in the northern third of the county

and the West Gulf Coastal Plain in the

southern two thirds (Fig. 1). All rock types

exposed in these provinces are

sedimentary, but their ages and histories

are strikingly different.

6

Rocks of the Ouachita Mountains in

Howard County are between 488 and 299

million years old (Paleozoic Era). At that

time the area was an abyss, where

sediment accumulated in oceanic

environments up to thousands of meters

deep. Thousands of feet of sandstone,

shale, novaculite, and limestone bedrock

formed from this sediment. Eventually,

pressure from colliding plates in the earth’s

crust caused the bedrock to rise above sea

level, deform, and fracture. Thus, the

Ouachita Mountains were formed. Over

millions of years, these up-thrown rocks

eroded into the ridges and valleys we see

today. The prominent ridges are typically

made of erosion-resistant rock, such as

sandstone or novaculite, while the valleys

are mostly easily-erodible shale. A gap in

the rock record that represents a period of

erosion/non-deposition, such as this, is

called an unconformity.

An unconformity occurs when no

rock is deposited in an area, or erosion

removes rock for a significant period of time,

so that there is a gap in the rock record for

that time span. There are two major

unconformities in Howard County (Fig. 2).

Minor unconformities also separate the

formations of the West Gulf Coastal Plain,

but those unconformities represent much

shorter time spans.

Figure 2: Stratigraphic column of Howard County

The oldest major unconformity is

between the Ouachita Mountain rocks and

7

the rocks of the West Gulf Coastal Plain.

From about 250 to 145 million years ago,

Howard County was above sea level and

erosion, rather than deposition, was taking

place. Around 145 million years ago

(Cretaceous Period), southern Arkansas,

including southern Howard County,

subsided below sea level, as the Gulf of

Mexico was forming. Now inundated, new

sediment began accumulating in the shallow

sea covering southern Arkansas.

Eventually, that sediment became the rocks

of the West Gulf Coastal Plain (Figs. 1, and

2, and plate 1). Because the strata of the

Ouachita Mountains are tilted and the West

Gulf Coastal Plain strata are relatively flat-

lying, we refer to this contact as an angular

unconformity (Fig. 3).

Figure 3: Angular unconformity between the Pennsylvanian Johns Valley Formation (lower sandstone) and the Cretaceous Trinity group (upper gravel)

Rock layers of the West Gulf Coastal

Plain typically strike east-west and dip

gently to the south at about 1o. Unlike the

Paleozoic rocks, which are very hard, the

Cretaceous rocks are, for the most part,

unconsolidated and erode easily. For

convenience, geologists divide Cretaceous

rocks into lower and upper units (Fig. 2),

both of which were deposited in shallow

nearshore marine environments between

146 and 66 million years ago. The Lower

8

Cretaceous rocks consist mostly of cross-

bedded sandstone, but include two intervals

of fossiliferous limestone. Upper

Cretaceous rocks are of variable lithology,

but consist largely of sand, clay, gravel,

chalk, tuff, and marl: unconsolidated marine

clay and calcareous sediment.

The younger major unconformity in

Howard County is still developing, as rocks

of the West Gulf Coastal Plain have been

elevated above sea level and subject to

erosion since the end of the Cretaceous

Period, 66 million years ago. On this

erosion surface, Quaternary (2.6 million

years ago to present) “rock” is being

deposited today. The Quaternary “rock”

units on the Geologic Map of Howard

County (Plate 1) are not true rocks, but

rather sediment that has recently (last 2.6

million years) accumulated along streams.

Quaternary alluvium consists of sand, silt,

clay, and gravel, deposited in floodplains

and channels of modern streams.

Quaternary terrace deposits have the same

composition as alluvium, but were deposited

in higher-elevation floodplains and channels

that streams occupied in the recent past.

Stratigraphy

Paleozoic (444 - 299 million years ago)

The Silurian aged (444 – 416 million

years ago) Blaylock Formation is the oldest

rock formation that outcrops in Howard

County. It consists of tan to gray, fine- to

medium-grained sandstone, interbedded

with black fissile shale and rarely contains

graptolite fossils and trace fossils. The

Blaylock Formation is exposed in northeast

Howard County (Plate 1).

Also of Silurian age, the Missouri

Mountain Formation was deposited on the

Blaylock Formation. It consists of shale

interbedded with conglomerate, as well as

novaculite and sandstone. Few identifiable

fossils have been recovered from this unit.

The Missouri Mountain Formation crops out

in northeast Howard County (Plate 1).

The Arkansas Novaculite was

deposited on the Missouri Mountain

Formation between the Devonian Period

9

and the Early Mississippian Period (416 to

347 million years ago). Three divisions of

the Arkansas Novaculite are recognized.

The lower division is white massive

novaculite with some interbedded gray

shale near the base. The middle division is

greenish to dark-gray shale, interbedded

with many thin beds of dark novaculite. The

upper division is white, thick-bedded, and

commonly calcareous. The Arkansas

Novaculite occurs in northeast Howard

County (Plate 1). It is an important

commodity, quarried for application as an

abrasive (for instance, whetstones).

The Stanley Formation rests

conformably on the Arkansas Novaculite

and spans part of the Mississippian age

(about 347 – 318 million years ago). It is

composed predominantly of grayish-black to

brownish-gray shale, with lesser amounts of

thin-bedded to massive, fine-grained, gray

to brownish-gray, feldspathic sandstone,

dark green to black tuff (the Hatton Tuff),

and chert. After weathering, the sandstone

is generally porous and brown and the shale

is olive-gray.

The Jackfork Formation conformably

overlies the Stanley Shale. It is Early

Pennsylvanian age, 323 to 315 million years

ago. It consists of thin- to medium-bedded,

fine- to coarse-grained, brown, tan, or

bluish-gray quartzitic sandstone, with lesser

amounts of brown silty sandstone, and

charcoal-colored shale.

The Johns Valley Formation is the

youngest Paleozoic rock exposed in

Howard County and it rests conformably on

the Jackfork Formation. It was deposited

during the Pennsylvanian Period, between

318 and 299 million years ago. It is

composed of black shale with numerous

intervals of brownish sandstone. It also

contains small amounts of gray-black

siliceous shale and chert. The Johns Valley

locally contains exotic boulders thought to

have been deposited by mass wasting

events.

10

Cretaceous (146 – 66 million years ago)

The Lower Cretaceous Trinity Group

has a wide range of lithologies: sand,

gravel, clay, limestone, gypsum, and

celestine. It is primarily composed of fine-

to medium-grained, cross-bedded, white to

red sandstone that is locally barite

cemented. Clay of the Trinity Group,

though not abundant, is tan, light-gray, gray,

and brown. The base of the Trinity Group

contains abundant gravel, mostly in the size

range of 1 to 6 in. (2 – 15 cm). There are

numerous gravel pits developed in this

interval north of Dierks, Arkansas. Above

the gravel horizon and interbedded with the

sandstone intervals are two limestone

members: the Dierks Limestone and the

DeQueen Limestone. The Dierks

Limestone Member is 30 – 60 ft. (9 – 18 m)

of fossiliferous limestone, interbedded with

green and gray calcareous clay. The oyster

fossil Ostrea franklini is common in the

Dierks Limestone Member (Miser and

Purdue, 1929) (Fig. 4). Outcrops of this

member are exposed east of the Cossatot

River. The DeQueen Limestone Member

consists of up to 100 ft. (30 m) of

interbedded, fossiliferous limestone,

calcareous clay, gypsum, and celestine.

Cassiope branneri and Ostrea franklini are

common fossils in the DeQueen Limestone.

Gypsum and celestine increase in

abundance toward the east side of the

county, where they outcrop as thin beds and

lenses (Fig. 5). The DeQueen Limestone

Member is also known for its dinosaur

tracksites (Fig. 6). One significant tracksite

was unearthed and studied in 1983 and a

second in 2011. These tracksites are

approximately 4.25 miles (7 km) apart.

There are barite roses and disc-shaped

barite dollars in the Trinity Group on the

west side of the county (Fig. 7). Asphalt

impregnated sands and gravels, when

present in the Trinity Group, are found

below the DeQueen Limestone.

The oldest Late Cretaceous

formation in Howard County is the

Woodbine Formation. It rests

unconformably on the Trinity Group. It is

approximately 200 ft. (61 m) thick and

consists of gravel, water-lain tuff, sand, and

clay. The gravel is found at the base of the

unit and can be up to 60 ft. (18 m) thick, but,

is generally 20 ft. (6 m) thick. The average

clast is about 2 in. (5 cm) in diameter, sub-

rounded to rounded, and composed of chert

or novaculite (Fig. 8). Some highly-altered

igneous pebbles have also been noted in

the basal gravel. The water-lain tuff is

cross-bedded, and blue to green on freshly

broken surfaces. Weathering of the tuff

produces distinctive, red, waxy clay.

12

Figure 8: Basal Gravel of the Woodbine Formation

The Tokio Formation rests

unconformably on the Woodbine Formation

and consists of clay, sand, and gravel. A

gravel unit at the base of the formation is

approximately 30 ft. (9 m) thick and consists

of sub-rounded to rounded grains, ranging

from pebble- to cobble-sized. The average

grain is about 1 in. (2.5 cm) in diameter and

is typically composed of novaculite, chert,

quartz, sandstone, or quartzite (Fig. 9). The

clay of the Tokio Formation is dark gray to

almost white. The dark gray clay is

fossiliferous and contains plant fragments,

and plant and shell impressions. Some of

the lighter colored clay beds are altered

volcanic ash. The clay content of the unit

increases westward. Sandstone of the

Tokio Formation is fine- to medium-grained,

sub-rounded to rounded, and cross-bedded.

Glauconite and ilmenite are accessory

minerals in the sandstone. The Tokio

Formation is about 300 ft. (91 m) thick.

Figure 9: Basal gravel of the Tokio Formation

The Brownstown Formation rests

unconformably on the Tokio Formation and

consists of fossiliferous, gray to dark gray

marl and sandy marl. The marl units are

fairly uniform in thickness across the county.

The most recognizable fossil in this unit is

the oyster Exogyra ponderosa (Fig. 10).

13

The Brownstown Formation is about 240 ft.

(73 m) thick.

Figure 10: Exogyra ponderosa

The Ozan Formation rests

unconformably on the Brownstown

Formation. It is marl, sandy marl,

glauconitic marl, and sand. The Buckrange

Sand Member, at the base of the unit, is

about 20 ft. (6m) thick. This sandy interval

contains glauconite, phosphate nodules,

black chert, and shark’s teeth. Marls of the

Ozan Formation are dark gray and

fossiliferous. Notable fossils include

Exogyra ponderosa and Ostrea falcatta

(Fig. 11) (Dane, 1929). Teeth and bones of

the mosasaur, a large extinct marine reptile,

have also been identified in this unit (Fig.

12). The Ozan Formation is approximately

200 ft. (61 m) thick.

Figure 11: Ostrea falcatta

Figure 12: Teeth and bones of the mosasaur

The Annona Formation consists of

massive, slightly fossiliferous chalk and

rests unconformably on the Ozan

Formation. On a freshly broken surface, the

chalk is blue-gray. After weathering, it is

typically white (Fig. 13). Like glass, broken

surfaces of the chalk display conchoidal

14

fracture. A noted fossil from the unit is

Echinocorys cf. E. texana (Dane, 1929)

(Fig. 14). This unit is about 120 ft. (37 m)

thick.

Figure 13: Chalk of the Annona Formation

Figure 14: Echinocorys cf.E. texana

Above the chalk of the Annona

Formation is the Marlbrook Formation. It

consists of blue-gray marl that is light-gray

after weathering and is fossiliferous. Noted

fossils include Ostrea falcatta, Exogyra

ponderosa, and reptilian fossils. It is

approximately 220 ft. (67 m) thick.

The Saratoga Formation was

deposited on the Marlbrook Formation and

is a sandy, glauconitic chalk. On a freshly-

broken surface, it is blue-gray, but after

weathering, it is almost white. It is typically

between 30 and 70 ft. (9 and 21 m) thick

and is fossiliferous.

The youngest Upper Cretaceous unit

in Howard County is the Nacatoch

Formation. It rests on the Saratoga

Formation. The Nacatoch Formation

consists of cross-bedded, fine- to medium-

grained quartz sand, marl, sandy

fossiliferous limestone, glauconite, and

other clays. In Howard County, the

Nacatoch Formation is about 40 ft. (12 m)

thick.

Tertiary and Quaternary (66 million years

ago to present)

All units mapped that are younger

than Cretaceous, including the Tertiary and

15

Quaternary units, are unconsolidated sand,

silt, clay, and gravel.

Mineral Resources

Current Mining

Industrial minerals currently being

extracted from Howard County are gypsum,

sand and gravel, clay, and shale (Howard,

2012) (Plate 2). Gypsum is produced from

the DeQueen Limestone Member of the

Trinity Group, north of Nashville, Arkansas.

The gypsum is mined primarily from three

beds, which are about 20 ft. thick combined.

Two additional gypsum lenses are found

locally but are not used as ore. Gypsum is

present from Plaster Bluff along the Little

Missouri River, westward, to the Saline

River. It is used in the manufacture of

drywall. The drywall is marketed from

Texas to Florida and, northward, into the

Ohio Valley Region. Unconsolidated units

of the Cretaceous-aged Trinity Group,

Woodbine Formation, and Tokio Formation,

and Quaternary-aged alluvium, are quarried

to produce aggregate material, sand and

gravel, and clay. Much of this material is

utilized locally. Shale, from Paleozoic units,

is mined for fill material and as top dressing

for secondary roads.

Historical Mining

In the northern part of the county,

lead, zinc, and mercury were prospected,

but only mercury was commercially mined

(Stroud et al., 1969). Lead and zinc are

typically found in the minerals galena and

sphalerite, respectively, in faults and quartz

veins of the Jackfork Formation. Both were

prospected in T7S, R29W but were never

produced (Plate 2). Cinnabar, the ore of

mercury, is present in an east-west-trending

zone across the northern part of the county.

Cinnabar was mined from the Stanley

Formation in T7S, R27W (Plate 2). Total

production of mercury from this location was

ten to twelve, 76 pound flasks (Stroud et al.,

1969). Quartz veins that bear cinnabar also

contain the accessory minerals barite,

limonite, and dickite. Shale collected from

the Stanley and Jackfork formations in

16

Howard County has been utilized in the

production of brick.

In central and southern Howard

county, historical mineral production

included chalk, celestine, barite and heavy

mineral sands. Chalk was produced from

the Annona Formation in the vicinity of

Okay, Arkansas, T11S, R27W, for use by

the cement industry (Plate 2).

Celestine, which is ore of strontium,

was produced from thin beds in the lower

part of the DeQueen Limestone Member of

the Trinity Group (Plate 2). The principle

use of Strontium is in fireworks and other

pyrotechnical applications. Production of

celestine was centered in T7S, R27W; T8S,

R28W; and T8S, R29W (Plate 2). Total

production was 90 tons of ore (Stroud et al.,

1969). The celestine ranged from 5.5 to

97.0% SrSO4, and less than 1% SrCO3

(Stroud, et al, 1969).

Barite was produced in Howard

County, from 1963 to 1965 from two areas:

one east of Dierks, Arkansas and the other

south of Dierks (Plate 2). East of Dierks,

barite was mined from several open pits in

the pike gravel. It occurs as cement in

gravel and sandstone, and fills veins and

fractures in the unit. Reserves were

estimated at 5 million tons, containing 5 %

barite. In the deposit south of Dierks, the

barite occurs in concretions and cement, in

sandstone beds of the Trinity Group. That

deposit covers 12 acres, with reserves

estimated at 300,000 tons, containing 10

percent barite.

Heavy mineral sands were mined

from an area northwest of Mineral Springs,

Arkansas, T10S, R28W (Plate 2), from the

upper part of the Tokio Formation.

Titanium-bearing mineral grains collected

from the sands include ilmenite, rutile,

leucoxene, and anatase. Accessory

minerals include monazite, zircon,

tourmaline, spinel, andalusite, pyroxene,

amphibole, and kyanite. Original source

areas for much of the ilmenite include

Magnet Cove, Arkansas and other igneous

17

intrusions in the surrounding area (Hanson

1991, 1997).

Water Resources

Surface water resources of Howard

County are rivers, streams, and reservoirs.

Notable surface water impoundments

include Millwood Lake, Dierks Lake, and

Gillham Lake. Groundwater is sourced

from sand and gravel units of the Trinity

Group, Tokio Formation, and terrace

deposits in the West Gulf Coastal Plain.

Wells in the area typically have an average

initial output of about 25 gallons (95 liters)

per minute and are less than 250 feet (76

m) deep (determined from water well

completion reports on file at the Arkansas

Geological Survey). Wells in the Ouachita

Mountains region of Howard County

primarily produce from fracture systems and

quartz veins. Wells drilled into shale and

sandstone units in this area produce limited

ground water, and output is difficult to

predict.

Fossil Fuel

The potential for fossil fuel

production in Howard County is very low. At

the present time, neither oil nor gas is

produced within the county. A three foot

bed of coal was discovered while drilling a

water well in T10S, R27W. Sufficient data

does not exist to evaluate the resource

potential of that coal (Stroud, et al., 1969).

Geohazards

Although limestone is present in the

county, there is little or no potential for karst,

such as sinkholes, to develop. The

limestone beds of the county are thin and

are interbedded with clay, which reduces

permeability and limits its susceptibility to

karst development.

Calcareous clays, such as those

found in the Brownstown and Ozan

formations and parts of the Trinity Group,

have the potential to shrink and swell. The

foundations of buildings that are built on

those marl units may be vulnerable to

cracking and settling.

18

Landslide potential is relatively low

in the county, however, in areas that are

underlain by shale or other poorly

consolidated rock or sediment, the

likelihood of landslide is higher. A good

natural defense against landslide is

vegetation. Stripping land of vegetation

exacerbates slope instability and should be

avoided when possible.

Finally, a significant geohazard

threat to Howard County is the pollution of

the water supply, both groundwater and

surface water. Fresh water is a necessity

for every person plant and animal in the

county. Proper handling and disposal of

waste and other potential contaminants, and

good agricultural practices are significant

defenses against water pollution.
