NEW OCCURRENCES OF ANDUOITE, (Ru,Os)As2, FROM CHROMITE DEPOSITS OF UKRAINE AND ALBANIA
Bibliographic record
Abstract
Two new occurrences of anduoite, (Ru,Os)As2, a rare platinum-group mineral (PGM), are reported from chromitites, one from the Kapitanov deposit, Ukrainian Shield, Ukraine, and the other from the Maja e Sukes deposit, Tropoja ophiolitic massif, Albania. At Kapitanov, anduoite occurs as discrete, homogeneous, euhedral crystals (6–9 and 1–2 � m) enclosed in two chromian spinel grains devoid of fractures. At Maja e Sukes, one crystal of anduoite (3 � m in diameter) belongs to a complex polyphase assemblage of PGM comprising sperrylite, hollingworthite and an unnamed sulfarsenide of Rh, Ir, Pd and Ni. The chemical composition of anduoite is comparable in both deposits: (Ru 0.79–0.80Os0.10–0.11Ir0–0.03Rh0.03–0.04Pt0–0.01Pd0.01–0.02Ni0–0.04)� 0.98– 1.01(As1.98–2.01S0.01–0.02)� 1.99–2.03. These examples of anduoite have a lower content of Ru than that described from the type locality in Tibet. A magmatic origin is proposed.

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.
