Fluid evolution and pressure regimes in the Campbell - Red Lake gold deposit, Red Lake mine trend, Red Lake, Ontario: fluid-inclusion evidence for a protracted, highly dynamic hydrothermal system
Bibliographic record
Abstract
Fluid inclusions were studied in quartz grains assigned to pre -, syn -, and post - main-stage gold mineralization (Q1, Q2, and Q3) in the Campbell-Red Lake gold deposit. Carbonic fluid inclusions, dominated by CO2 with variable amounts of CH4 andN2, are predominant in all stages. Aqueous inclusions are rare in Q1 and Q2, but common in Q3. Using homogenization temperatures of 350º, 390º and 320ºC for aqueous inclusions in Q1, Q2, and Q3 respectively, fluid pressures of up to 2706, 2574, and 1000 bars (corresponding to lithostatic loads of 10.2, 9.7 and 3.8 km) have been obtained from the isochores of carbonic fluid inclusions. Large fluctuations in fluid pressure within individual stages are attributed to variation between lithostatic and subhydrostatic regimes in relation to structural evolution. The extreme scarcity of aqueous inclusions in Q1 and Q2 suggests a 'dry' (water-deficient) carbonic-rich hydrothermal system with CH4 and N2, whose gold transporting capacity needs further examination.

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.
