Characterization of Indicator Minerals and Till Geochemical Dispersal Patterns Associated with the Pine Point Pb-Zn Mississippi Valley-type Deposits, Northwest Territories, Canada
Bibliographic record
Abstract
Surficial geological mapping of the Pine Point region records three, possibly four, directions of ice flow. Dispersal of metal-rich till was primarily to the north and west indicating that at least the oldest ice flow trajectory was in contact with mineralized bedrock. This metal-rich till includes indicator minerals (sphalerite, galena, pyrite and smithsonite) and pathfinder elements (Zn, Pb, Fe, Cd, S and Tl). Dispersal of indicator minerals and pathfinder elements are strongest in the direction of the oldest ice flow trajectory immediately down ice of the deposit and are detectable at the surface within 500 m of the deposit. Sulphur and Pb isotopes from sphalerite and galena grains in till and bedrock are consistent with a Pine Point provenance.
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.
