Isotope dilution with high pressure asher acid digestion for the determination of platinum group elements in chromitite from katpal chromite mine in the Sukinda Ultramafic Complex, Eastern India
Bibliographic record
Abstract
Chromitite samples were collected from a core from the Katpal chromite mine of Sukinda chromite field \nfor characterization of mineralogy especially the platinum group minerals (PGM). Isotope dilution with \nHigh Pressure Asher (HPA-ID) technique has been used in this study to evaluate its ability to determine \ncompositions from small quantities of sample (two grams of sample). Enrichment of Iridium group of \nplatinum elements (IPGE) (Ir ~ 1717 ng/g; Ru ~ 20 ng/g) at depth of ~ 35-80 m in the investigated core \nsuggests the presence of a strong potential zone for IPGE mineralization. The obtained data suggests \nsimilarities with the ‘Reef-type’ mineralization.

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.
