Waulsortian Lithofacies of the Mississippian Souris Valley Beds (Lodgepole Formation), Williston Basin, Southeastern Saskatchewan, Canada
Bibliographic record
Abstract
Waulsortian lithofacies identified in the subsurface of the Williston Basin of southeastern Saskatchewan are contained in the slope-to-basin transition of the Souris Valley Beds (Lodgepole Formation).Cores from three wells, 07-11-013-30W1M, 12-08-009-30W1M and 05-07-009-30W1M, are characterized by four objective (OL) and subjective (SL) lithofacies: interbedded bryozoan grainstone-packstone and wackestone-packstone (OL1), mudmound core (SL1); crinoidal and stromatactis mudstone-packstone (OL1), mud-mound drape (SL2); rubified crinoidal mudstone (OL3), saprolitic mud-mound drape (SL3); and cherty dolostone (OL4), pedogenic groundwater dolocrete (SL4).These lithofacies reflect the evolution of carbonate accumulation from deep-water settings to pedogenic modification as a result ofsubaerial exposure.Lithofacies 1 (OL1/SL1), the mud-mound core fades, was analyzed further with the aid of optical microscopy, elemental microprobe WDX analyses and stable-isotope mass spectrometry.OL1/SL1 was chosen for these analyses because it is the main reservoir elsewhere in the Williston Basin and is the least modified by pedogenic alteration.
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.
