COMPOSITIONAL VARIATIONS IN PLATINUM-GROUP MINERALS AND GOLD, KONDER ALKALINE-ULTRABASIC MASSIF, ALDAN SHIELD, RUSSIA
Bibliographic record
Abstract
Les mineraux du groupe du platine provenant du complexe de Konder, ultrabasique, alcalin et zone, situe a l'est du bouclier d'Aldan, en Russie orientale, sont surtout representes par l'isoferroplatine, formeen deux generations, les deux ayant des teneurs en fer allant de 7.5 a 11.5% (poids). Une generation de haute temperature est saturee avec les autres elements du groupe du platine sous forme d'impuretes: jusqu'a 5.3% Ir, 2.9% Os, et 1.8% Rh (base ponderale). En revanche, l'isoferroplatine tardif contient moins de 1.9% Ir, 1.0% Os, et 0.6% Rh. Parmi les mineraux accessoires du groupe du platine, on trouve une grande variete de solutions solides faisant partie du systeme Os-Ir-Rh-Pt, tetraferroplatine, tulameenite, hongshiite, mineraux des series erlichmanite-laurite et irarsite-hollingworthite, sperrylite, bismuthures, antimoniures, tellurures, stannures, et hydroxydes. Les assemblages contiennent possiblement de nouvelles especes minerales: ruthenium natif, l'analogue palladifere de la hongshiite, Pt 2 As 3 , et l'analogue platinifere de la konderite et de l'inaglyite, entre autres, qui forment des liseres autour des grains d'isoferroplatine et des inclusions dans cette phase. Nous observons pour l'or une morphologie et une distribution semblables a celles de l'isoferroplatine; l'or est lie a de rares lentilles de sulfures et des impregnations dans la dunite (or de haute temperature, porteur de Cu, Pt, et Pd), et des venues de monzodiorite recoupant la dunite (or en moyenne ou faible teneurs, a faible contenu en impuretes).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
