Study of Diamonds from Chromitites in the Luobusa Ophiolite, Tibet
Bibliographic record
Abstract
Diamonds have been reported from alpine-type ultramafic rocks and chromite ores by the authors in 1980. But unfortunately so far the reported diamonds in Tibet are unconfirmed. This paper deals with the new occurrence and characteristics of diamonids, which are recovered from chromite ores in the luobusa ophiolite. About 25 grains of diamond and alout 70 sorts of associated minerals have been discovered, including native elements: Cr, Cu, Ni, Fe, C, Si, Au, Pb, W, Ir, Os, Ru; Alloys: Fe-Ni, Fe-Co, Fe-Mn, Fe-Si, Fe-Ni-Cr, Fe-Ni-Co, Cr-C, Si-C, Ir-Os, Os-Ir, Os-Ir-Ru, Fe-Pt, and silicate and sulfides.

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.
