Geological relationships at Upper Arrow Lake, southeastern British Columbia: implications for the Milford and Kaslo groups
Bibliographic record
Abstract
Devonian strata correlative with the Devonian Silver Creek and Chase formations have recently been recognized beneath argillaceous Milford Group rocks on the western margin of the northern Kootenay Arc at Upper Arrow Lake. New mapping demonstrated that those argillaceous rocks conformably overlie the Devonian units, suggesting that that component of Milford Group and overlying mafic volcanic rocks, which had both been assigned to the Slide Mountain terrane, were deposited on Devonian continental margin strata and are therefore parautochthonous. That these units were deposited on equivalents of the Silver Creek Formation implies a stratigraphic connection to the Eagle Bay assemblage. Detailed mapping in the vicinity of the Northeast Arm of Upper Arrow Lake characterized an assemblage of phyllite, limestone, quartzite, and greenstone that is interpreted as resurfacing of the Index Formation along the western limit of the Lardeau Group.

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.
