Lithology, mineralogy, and geochemistry of glacial sediments overlying kimberlite at Smeaton, Saskatchewan
Bibliographic record
Abstract
Quaternary glacial sediments over 100 m thick overlie interbedded Cretaceous shale and extrusive kimberlite debris at a site near Smeaton, Saskatchewan. These sediments consist of diamicts interpreted as till, with minor sand, silt, and clay interbeds. The uppermost sediments, 34.6 m thick, contain few kimberlite indicator minerals, but are rich in shield debris, thus resembling, in composition, northerly-derived till that occurs at surface throughout the region between the exposed shield and the North Saskatchewan and Saskatchewan rivers. Underlying sediments, 33.6 m thick, contain numerous kimberlite indicator minerals, and are carbonate rich to very carbonate rich, resembling in composition northeasterly to easterly derived surface till throughout the region south of the Saskatchewan River and east of The Missouri Coteau. The lowermost sediments, 32.2 m thick, contain few kimberlite indicator minerals, but contain both shield and carbonate erratics in intermediate amounts, and are thus of an approximately northeasterly derivation.
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.
