Abstract
Copyright information:Taken from "Physicochemical conditions and timing of rodingite formation: evidence from rodingite-hosted fluid inclusions in the JM Asbestos mine, Asbestos, Québec"http://www.geochemicaltransactions.com/content/8/1/11Geochemical Transactions 2007;8():11-11.Published online 25 Oct 2007PMCID:PMC2174467. [59] for the footwall at the base of the Thetford-Mines ophiolite (dashed lines). Only the paths that cross the P-T conditions determined by Clague et al. [65] and Feininger [66] for the metamorphism in the footwall at the base of the Thetford-Mines ophiolite are reproduced. The P-T-t paths define a range of geotherms that transect the calculated trapping conditions of type 2b fluid inclusions in rodingitized diorite. Trapping conditions for type 2a fluid inclusions in samples Gran-1b and Slate-1a, and for two type 1 fluid inclusions in vesuvianite (isochore indicated by solid line labelled 'Ves'), lie below those geotherms. The diagram also show the limits of stability of forsterite and antigorite in the system MgO-SiO-HO, and prehnite, in part, calculated using THERMOCALC v2.3 [42,43] assuming pure phases. The wet pelite solidus is after Thompson and Algor [67] and the limit for the stability of andalusite after Richardson et al. [68]. The diagram suggests emplacement of andalusite granites at relatively shallow levels in the Asbestos ophiolite, and possibly through peridotites that were already serpentinized.

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.
