Lower and Middle Devonian outcrop stratigraphy of northeast British Columbia
Bibliographic record
Abstract
Presqu'ile Barrier reef strata are documented in six measured sections from southern Trutch and Halfway River map areas, Rocky Mountain Thrust Belt, northeastern British Columbia. They contain abundantly stromatoporoidal strata as young as mid-Givetian. Presqu'ile Dolomite is commonly developed in large masses within thick 'Upper Chinchaga to Slave Point Undivided' limestone successions in outcrop. Less extensive, white, hydrothermal dolospar is developed within relatively thin Dunedin Formation strata, particularly in slope settings immediately basinward of the Presqu'ile Barrier reef complex. Manetoe Dolomite occurs within Dunedin strata, even in northernmost sections. The Dunedin Formation's basal unconformity and its diachronous and gradational upper contact with the Besa River Formation are confirmed and documented. Lower to Middle Devonian siliciclastic units occur within the Laurier Embayment, a broad bypass channel through the Presqu'ile Barrier reef complex. Extensive Presqu'ile Dolomite occurs south of Laurier Embayment, similar to that in the nearby Clarke Lake gas field.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
