Abstract
The Bonnet Plume Basin is a physiographic and structural depression near the eastern margin of the Frontal Belt of the Cordilleran Orogen in northeastern Yukon, Canada. It formed in early Late Cretaceous time by down-dropping Paleozoic strata along regional faults, and contains up to 7,500 m of clastic and carbonate sediments ranging from Precambrian to Tertiary in age. The oldest strata are Precambrian metasediments, which are unconformably overlain by a thick Paleozoic succession of marine mudstone and limestone. The Paleozoic sediments are unconformably overlain by the Bonnet Plume Formation, which is informally subdivided into a lower and upper unit. The lower Bonnet Plume Formation (Albian) consists of interbedded conglomerate, sandstone, mudstone and bituminous coal deposited in a marginal marine to fluvial environment, and the upper Bonnet Plume Formation (Maastrichtian to Paleocene) consists of fluvial sandstone, mudstone and lignite. Previous studies, based on regional geology, sediment type and stratigraphic thickness, concluded that the Bonnet Plume Basin has gas potential, but insignificant oil potential. However, these studies were not based on samples collected from within the basin. Two-hundred-twenty-eight samples collected from outcrop and drill core throughout the Bonnet Plume Basin were analyzed by Rock-Eval 6 programmed pyrolysis and combustion to assess the petroleum source rock potential of the strata. The results indicate the Bonnet Plume Formation is gas-prone and possibly oil-prone. Potential oil generation in the Bonnet Plume Formation is attributed to the occurrence of liptinite-bearing coal and previously unrecognized siliceous 'oil shale'. A hydrocarbon-rich tar associated with a naturally burning coal seam was also discovered in the

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.
