The Moberly Member (Waterways Formation) Outcrops in the Athabasca Oil Sands Region: A new look at a classic correlation
Bibliographic record
Abstract
Summary We present an updated correlation and composite section of the Moberly Member (Waterways Formation) outcrops in the Athabasca Oil Sands mining region in Alberta. Notable trends in the lithology and paleontology of the outcrops include (a) a southward increase in the argillaceous portion of the sediment in the lower part of the section and a northward increase in argillaceous sedimentation in the upper portion of the section; (b) a general decline in fossil abundance and richness diversity in the upper portion of the section, along with the disappearance of some fossil taxa; (c) a northeastsouthwest trend in the Moberly Member biostrome unit from one dominated by branching, bulbous, and tabular forms in the northeast to one with only massive stromatoporoids surrounded by Radiatrypa brachiopods in the south to a presumably offshore, non-biostromal unit containing a diverse fauna and heavily bioturbated with Thalassinoides burrow networks in the southwest.
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.
