Composition of Sphalerite from Quemont Mine, Quebec
Bibliographic record
Abstract
Sphalerite-bearing samples from the Quemont ore zones can be divided into two types--one in which the sphalerite coexists, over the dimensions of a polished section, with pyrite and pyrrhotite, and the other in which pyrite is the sole iron sulfide. Electron microprobe analyses show that 71 samples of sphalerite from the pyrite-pyrrhotite group range from 8.9 to 13.3 mole percent FeS, with a pronounced mode between 11 and 12 mole percent. 52 samples from the pyrite group show a wider range from 2.7 to 13.7 mole percent FeS, but also have the same most frequently occurring value. Mineralogical considerations suggest that the sulfide bodies may not presently constitute an equilibrium assemblage, but textural and geochemical relationships indicate that equilibrium was closely approached, on at least the microscale at which the analyses were performed, at some stage during the evolution of the ore deposits and that the equilibrium compositions have been preserved in the sphalerites. However, the corn-.positional data are in apparent disagreement with the conclusions reached in several recent experimental studies.

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.
