Canadian Mineralogist Vol. 23, pp.213-220 (1985) TITANIAN BERTHIERINE: A T|-RIGH SERPENTINE-GROUP MINERAL FROM THE PICTON
Bibliographic record
Abstract
ABSTRAcT A serpentine-group mineral, titanian berthierine, occurs in the groundmass of the Picton ultramafic dyke, near Pic-ton, southeastern Ontario. X-ray diffraction shows that it is isostructural with members of the serpentine group. It occurs as a cryptocrystalline aggregate of apparently fibrous, reddish brown crystals. Electron-microprobe ana-lyses show high TiO2 (18.5-20.5V0), FeO7Q3.7-26.20/o), and Al2O3 (8.6-16.l9o) and low SiO2 (21.8-26.590) and MgO (4.9-6.890) contents. The chemical formula of tita-

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.
