In contrast, the chemical variations observed in phosphates have been more rarely used as a tool for evaluating the degree of fractionation of pegmatites or their potential links to granites and/or anatectic events. In those cases the Fe/(Fe+Mn) ratio of primary phosphates has been taken into account in order to establish the fractionation degree of the hosting pegmatite, with this value decreasing with differentiation (e.g., Ginsburg 1960, Keller et al. 1994, Roda...

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.
