If the Shoe Fits: A Holistic Look at Viking Deposition in the Western Canada Sedimentary Basin
Bibliographic record
Abstract
Summary High resolution mapping of isopach values for the Viking Formation and its equivalents from over 250,000 wells provides a perspective of the Viking depositional system not seen previously through conventional mapping techniques. When combined with historical published data, core observations and petrography, a picture emerges of a large submarine system that demarcates the structurally-driven regional transition from N-oriented sediment transport and deposition typical of the underlying Mannville Group to SE-oriented sediment transport and deposition typical of the overlying Upper Cretaceous deltaic successions (e.g., Dunvegan, Cardium, Muskiki, Belly River, Horseshoe Canyon etc.). Isopach trends and geometries indicate there are likely two Cadotte, two Paddy and three Viking successions separated both spatially and temporally. The multiplicity is related to inversion of the Peace River Arch and a rotation of the marine depocenter. This perspective accounts for many if not most of the inconsistencies between previous depositional, sequence stratigraphic and biostratigraphic

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.
