Bowser-Sustut Current Knowledge

Regional Geological Framework Bowser and Sustut basins: Jurassic and Cretaceous clastic rocks that cover a large part of north-central British Columbia; about 1.5 times the size of Switzerland.

in the Intermontane Belt of the Canadian Cordillera, a region of low metamorphic grade relative to the bounding Omineca Belt (metamorphic) and Coast Belt (plutonic and metamorphic)

overlie Triassic and lower Jurassic volcanic arc rocks of Stikinia

basin rocks were deformed in Cretaceous time to form Skeena Fold Belt; the fold belt terminates (locally) on the NE in a frontal triangle zone within Sustut Basin strata

Bowser Basin is intruded on the west by early Tertiary plutonic rocks of the Coast Belt

basin rocks are overlain by minor late Tertiary and Quaternary volcanic rocks

Bowser Basin - more than 6000 m of sedimentary rock deposited in environments ranging from distal submarine fans and abyssal plain, to continental shelf, deltas, rivers, lakes, and alluvial fans. Mapped as lithofacies assemblages of the Bowser Lake Group. Includes Skeena Group (south).Age: Middle Jurassic to mid Cretaceous

Ritchie-Alger assemblage: submarine fan

Bowser-Sustut Current Knowledge Highlights of 2005 Fieldwork

Most collections of Bowser Lake Group where age could be determined are Late Jurassic, or latest Jurassic to earliest Cretaceous. Most Skeena Group samples yielded Early Cret. Ages (preliminary), a few mid Cretaceous. Next steps are to incorporate previous collections (after verifying locations).

Bowser-Sustut Current Knowledge Other research – Provenance and age constraints from Isotopic Systems (V.

McNicoll)

Combined cumulative probability plots have youngest peak at the depositional age of the rock determined paleontologically. To date >750 zircon grains from 14 samples analyzed.

The consistency with which the youngest peak is on the depositional age of the rock provides cautious optimism that we can use this method to determine the age of sections where fossils are lacking – target is unit boundaries.

Typical Bowser Lake Gp detrital zircons on SHRIMP mount

APPROACH – collect sandstone from strata whose age is well constrained paleontologically, and from diverse geography, map units, and ages. U-Pb SHRIMP analyses of detrital zircons provide a maximum age.

research and publication

Continue map compilation at 50K, 250K, and 500K scales

Continue analysis and integration of datasets

Interim reports, presentations

Final synthesis - digital basin atlas to encompass all data and interpretations (the plan, but subject to major revision pending budget allocation)

Bowser-Sustut Current Knowledge Summary

SOURCES OF RECENT INFORMATIONLatest project “Geosampler” CD with todays powerpoint presentations will be sent if you leave us a buisness card or send an emailSee our website!! www.bowserbasin.com But…please remember, material in ppt presentations, the website, and CD is not peer reviewed; the material is meant to aid in your understanding of the region, but not to be cited in formal publications unless it is already published (formally).

From field season - significantly refined distribution of map units in the southern basin; refinement of unit characteristics; completion of collection of sample suites for thematic studies.From ongoing work – major progress on a number of studies – thermal maturity, organic petrology, petroleum systems, thermal history (AFTT, paleomagnetism), provenance, paleontology, lithogeochemistry, seismic tomography, structural analysis.Several new publications of data and interpretations available.
