Petrography, quantitative mineralogy, and U-Pb geo- chronology of the Boundary Zone Zn-Pb ± Ag deposit, Yukon, Canada
Bibliographic record
Abstract
The Boundary Zone prospect (Yukon, Canada) is a Zn-Pb-Ag prospect hosted by siliciclastic rocks in the Macmillan Pass district. The main host units comprise the Late Ordovician to Early Silurian Duo Lake Formation and the Middle to Late Devonian Portrait Lake Formation. Sulfide mineralization is hosted in mudstones, conglomerates, diamictites, and volcaniclastic rocks, with stratabound, vein, and breccia-hosted sulfides consisting of sphalerite, pyrite, galena, with minor chalcopyrite and sulfosalts. This data publication comprises results of analyses conducted on drill core samples obtained from the Boundary Zone. The data originates from multi-scale petrographic examination, quantitative X-ray diffraction (QXRD), electron probe microanalysis (EPMA), and secondary ion mass spectrometry (SIMS) U-Pb fluorapatite geochronology. All the analyses were caried out at the GFZ German Research Centre for Geosciences, Potsdam, Germany.
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.
How this classification was reachedexpand
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.
