Giant quartz vein zones of the Great Bear magmatic zone, Northwest Territories, Canada
Bibliographic record
Abstract
The Great Bear magmatic zone, Northwest Territories, hosts numerous giant quartz veins and stockwork zones. These zones can be up to 100m wide and up to 10km long, with two or more generations of quartz. A few of the giant quartz vein zones host base-metal ± uranium mineralization, and some are proximal to mineralization, although most are barren. Cathodoluminescence imaging shows the quartz veins have complex growth zones and a trace element study suggests that these zones are the result of Al and Li substitution in the quartz lattice. Oxygen isotope (δ18Oqtz) values of quartz generally fall between +8 to +14.6‰ (VSMOW). Fluid inclusion homogenization temperatures range from 100 to 375˚C, and the fluids have variable salinities. The fluids that created the giant quartz veins are epithermal in nature with a meteoric water ± brine signature, and formed as a result of multiple fluid pulses and re-fracturing events.

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.
