Till geochemical signatures of the Izok Lake Zn-Cu-Pb-Ag volcanogenic massive sulphide deposit, Nunavut
Bibliographic record
Abstract
As part of the Geological Survey of Canada's Geo-mapping for Energy and Minerals Program (GEM, 2008 - 2013), glacial dispersal down ice from a polymetallic volcanogenic massive sulphide (VMS) deposit at Izok Lake, Nunavut was studied. Analysis of samples collected at, and down ice of, the Izok Lake Zn-Cu-Pb-Ag VMS deposit indicate that Zn, Cu, Pb, Fe, Ag, Cd, Sb, Bi, Hg, Se, In, and Tl are pathfinder elements for the Izok deposit in the <0.063 mm fraction of till. Pathfinder elements indicate that metal-rich debris from the deposit was glacially dispersed at least 8 km down ice, generally to the northwest. Of the pathfinder elements, Zn has the highest contents in till immediately down ice of the deposit.
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.
