Carbonate-hosted Zn-Pb deposits in southern British Columbia - potential for Irish-type deposits
Bibliographic record
Abstract
Carbonate-hosted Zn-Pb deposits of the Kootenay Arc are hosted by deformed Lower Cambrian, platformal carbonate rocks of the Badshot Formation or its equivalent, the Reeves member of the Laib Formation. The deposits range in size from 6 to 10Mt and contain 3 to 4%Zn, 1 to 2%Pb, 0.4% Cd, and traces of Ag. They are essentially stratabound and stratiform lenticular concentrations of sulphide minerals (sphalerite, galena, pyrite, local pyrrhotite, and rare arsenopyrite) in isoclinally folded dolomitized or silicified carbonate rocks. The origin of these deposits is enigmatic. Some are analogous in their geological setting and features to the Irish-type carbonate-hosted Zn-Pb deposits.
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.
