Synvolcanic and younger plutonic rocks from the Blake River Group: Implications for regional metallogenesis: economic geology, v
Bibliographic record
Abstract
The Blake River Group of the Abitibi greenstone belt is host to the well-known volcanogenic massive sulfide (VMS) deposits of the Noranda camp, Québec, Canada. In the Noranda camp massive sulfide deposits are spatially associated with the coeval Flavrian-Powell intru-sive complex, which is interpreted to have driven hydrothermal circulation that formed the deposits in the camp. In the western Blake River Group in Ontario there are also abundant intrusive rocks, yet relatively in-significant accumulations of VMS deposits. These intrusive rocks are younger (2686.9 ± 1.2 and 2688.5 ± 2.3 Ma) and are associated with porphyry-style Cu-Mo-Au mineralization with Re-Os molybdenite ages of 2682.4 ± 5 Ma. The intrusions are also smaller in areal extent and do not have a temporally extended, polyphase his-tory like the Flavrian-Powell intrusive complex. The intrusions of the western Blake River Group can also be distinguished by lithogeochemical attributes and a distinct petrological history compared to the Flavrian-Powell intrusive complex. They have lower total Y, Yb,

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.
