Deposit, New Brunswick: Mineralogy, Geochemistry, Alteration, and Hydrothermal Regimes
Bibliographic record
Abstract
The Lake George antimony deposit consists of stibnite-bearing quartz veins which transect tightly folded Silurian graywacke, siltstone, and shale of the Fredericton trough. The veins are of two orientations: 0000/35 ø E (Lawrence vein) and 0900/33 ø N (Hibbard and Prout veins). To date, approximately 1 million short ons of ore grading 3.0 to 3.5 percent Sb have been mined from Hibbard, the dominant vein. Stibnite-bearing quartz veins transect he contact metamorphic aureole of a small grano-diorite porphyry stock which flanks the Devonian Pokiok batholith. The Hibbard vein refracts through folded country rocks, resulting in troughs and crests in the plane of the vein. Ap-proximately 80 percent of the ore mined from the Hibbard vein has come from one northeasterly trending ore shoot which formed at the intersection of the Hibbard vein with a synclinal axis in the country rocks. Three chemically distinct alteration zones have been recognized. The first is a domain of fracture-controlled argillic alteration rich in arsenopyrite, pyrite, and pyrrhotite which transects the preexisting contact metamorphic aureole. The second is a thin siliceous rind which transects

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.
