Hydrothermal mineralization and mineral chemistry of arsenides and sulfarsenides in the Fe-Co-Ni-As-S system and introduction of three unknown minerals from the Port Radium IOCG deposit, Northwest Territories, Canada
Bibliographic record
Abstract
Abstract The Port Radium deposit is the result of intrusion of the Mystery Island felsic-intermediate plutonic complex into the ~ 1.885 Ga supracrustal marine sedimentary rocks and volcanic suits, which formed a variety of mineralization styles from iron oxide-copper-gold (IOCG) to epithermal. Extensive and intensive hydrothermal alterations including albitic, magnetite-actinolite-apatite, potassic ± albitic, phyllic, and propylitic prepared a ground for the main sulfide, sulfarsenide and uraninite mineralization during last stage of hydrothermal activity. Scarce and weak sulfide mineralization started from the beginning of the hydrothermal activity and reached to the strongest state during epithermal stage. In addition to the common arsenides and sulfarsenides, three unknown sulfarsenides were also found: (Co0.96Ni0.45Fe0.03)S0.27As4 which is probably a solid solution product of cobaltite and gersdorfite; (Ni2.13Co0.38)S0.97As4 and (Ni1.83Co0.83)S1.25As4 which are chemically comparable to the Port Radium rammelsbergite with substantial addition of S and Co; they could also be the solid solution product of gersdorfite-cobaltite or safflorite-rammelsbergite.

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.
