Abstract

fetched live from OpenAlex

Nous documentons la presence de metapelites ayant des niveaux anormalement eleves de plusieurs elements de transition, y inclus V, Cr and Zn, dans une suite de roches archeennes de la region de Paradise Basin, dans la chaine de Wind River, au Wyoming. Ce sont des roches a sillimanite contenant jusqu'a 0.56% de V 2 O 3 et 0.32% de Cr 2 O 3 . Les mineraux coexistants sont aussi enrichis en V et Cr, y inclus le grenat, la hercynite et la biotite. Nous avons calcule les valeurs de KD pour V et Cr par rapport a Al pour le grenat, la sillimanite et la hercynite. La repartition de V/Al entre grenat et sillimanite est a peu pres egale (K D = 0.98), tandis que Cr/Al est fortement favorise par le grenat (K D = 6.9). La hercynite favorise fortement V/Al par rapport a grenat et sillimanite (K D egal a 15) et Cr/Al par rapport a grenat et sillimanite (K D egal a 27 et 189, respectivement). La hercynite contient en plus la plupart du zinc, sous forme de la composante gahnite, formant jusqu'a 10% d'une solution solide. Les conditions P-T enregistrees dans le coeur des mineraux de la matrice indiquent un paroxysme metamorphique au facies granulite, a plus de 9.5 ′ 0.1 kbar et 780 ′ 50°C. Dans cette matrice, la composition de la bordure des mineraux indique des conditions de plus faible intensite qui definissent une portion du trace P-T lors de la retrogression. Il n'y a aucune evidence d'introduction d'elements le long de veines ou de fractures: les quantites inhabituelles de V. Cr, et Zn seraient fournies par lessivage de materiaux plus anciens, deposes sous forme de grains clastiques.

Not 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.
