Pages 253–282 Stratigraphy of the Bad Heart Formation,
Bibliographic record
Abstract
The Upper Cretaceous (mid to late Coniacian) Bad Heart Formation consists of a ‘coarser ’ clastic succession (i.e. comprised of sandstone and ooidal ironstone with lesser conglomerate and siltstone) that typically is about 5 to 15 m thick and exists within a much thicker shale succession. The Bad Heart Formation has long been of potential economic interest because in the eastern Clear Hills region it hosts the thickest and most regionally extensive ooidal ironstone deposit in the Western Canada Sedimentary Basin. McLearn subdivided the Smoky River Group (then referred to by him as a formation) on a lithostratigraphic basis into three ‘members’: that is, “a lower shale [Kaskapau Formation], a middle sandstone — the ‘Bad Heart Sandstone’ [now a formation], and an upper shale [Puskwaskau Formation]”, with the type section for Bad Heart Formation being near the intersection of the Smoky and Bad Heart rivers. The data from this study have refined the previously published stratigraphic models, on a sequence stratigraphic basis, whereby three sequences

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.
