Canadian Mineralogist Yol.2.6, pp. 283-291 (1988) STOICHIOMETRY, STRUCTURE AND TWINNING OF GODLEVSKITE AND SYNTHETIC
Bibliographic record
Abstract
New electron-microprobe data for godlevskite from Noril'sk indicate a 9:8 (metal:sulfur) stoichiometry, con-sistent with the recent determination ofits structure in space group 422, and a formula of (Nis.7Fes.3)S6. Powder-diffraction intensity data confirm that low-temperature N! excess nickel sulfide is the qynthetic equivalent of godlev-skite, and also has a formal composition of NigSs; o-Ni7S6 disproportionates on annealing at,297oC to NieSs and Ni3S. The twin law for godlwskite from Noril'sk is estab-lished as: composition plane (l0l), twin axis normal to (l0l). The structure of godlevskite and synthetic NieSs is a hybrid of the structural elements of pentlandite, millerite and a-Ni7S6; unlike millgrils, a-Ni7S5 and headewoodite' the structure does not contain 3-fold clusters (Ni) of short Ni-Ni distances.

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.
