Petrochemistry of Lake George granodiorite stock and related gold mineralization, York County, New Brunswick
Bibliographic record
Abstract
The plagioclase-hornblende-biotite porphyritic granodiorite stock (Au = 32 ppb average) at the Lake George Sb-Au-W-Mo deposit, New Brunswick was sampled (10 samples) from drill core and ana-lyzed. It is metaluminous to weakly peraluminous (A/CNK = 0.99-1.13), calc-alkaline, Na 2 O>K 2 O, and has (La/Yb)N from 7.34 to 11.14 with a small negative Eu anomaly, as well as obvious negative Nb, Ti, Sr, and Ba anomalies. The Early Devonian ages and volcanic arc affinities (evolved I-type) favour a relation-ship with the Pokiok Batholith. Gold-bearing quartz-vein mineralization within the stock and in the proximal metamorphic aureoles highlights its metallogenic association with the intrusion. Silicification, sericitization, and chloritization of the stock associated with quartz-vein mineralization are enriched in Au, As, S, W, Mo, Rb, K, and B. These mineralizing fluids may be derived from the same granodioritic magma crystallizing at depth, although later than the W-Mo mineralization. The gold may be associated with an antimony mineralization episode.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
