Bibliographic record
Abstract
H2O, occurs as translucent white l-mm-sized hemispheres in cavities in a silicocarbonatite sill exposed at the Fran-con quarry, Montreal, Quebec. Major associated minerals are: albite, quartz, strontiodresserite, ialcite, dawsonite, ankerite and fluorite. Montroyalite hemispheres have a dull surface and a porcelaneous interior with a waxy lustre. Indistinct fibres radiate from the core and produce rough to botryoidal ofierior surfaces. Individual grains are irregu-lar to lath-shaped, up to 0.02 mm long and 0,005 mm tlick. The mineral is brittle; it has a white streak, Mohs hard-ness of 3%, uneven to splintery fracture, no observable cleavage; it is soluble in 1:l HCI at room temperature (20"C), and fluorescs white under botl long- and short-wave ultraviolet light. D(meas.) 2.677 g/cml. Montroyal-ite is biaxial negative, cr 1.515(5), p 1.530(5), 1 1.545(5), 2v(mas.) 80(10)0, 2v(calc.) 89'; Iis parallel or nearly parallel to tlre elongation of the lath, and X and Z make angles of about 45 " with the plane of the lath. Microprobe analyses and TGA,/EGA give Al2O3 28.8, SrO 27.7, CaO l. l, co2 9.2,}Izo 24,6,F 11.5, total 102.9, less o=F 4.84, total 98.06 weight 90. The material is not suitable for X-ray single-crystal studies. The strongest eight lines in the powder paftern [d in A(I)] are:

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.
