Garronite-Na, A New Zeolite Species From Mont Saint-Hilaire, Québec
Bibliographic record
Abstract
Abstract Garronite-Na, ideally Na 6 (Al 6 Si 10 O 32 ) · 7–10H 2 O, a new mineral species, was found in the Mont Saint-Hilaire quarry, Quebec. It occurs in vugs in sodalite syenite. The crystals are transparent to translucent, pale yellow in color, with a white streak and vitreous luster. Crystal aggregates are botryoidal masses up to 1.5 mm in size. The mineral is brittle with a good {011} parting. Associated minerals include aegirine, natrolite, gmelinite, and gonnardite. Garronite-Na is monoclinic, space group I 2, with unit-cell parameters refined from single crystal X-ray diffraction data: a 9.990(2), b 10.032(2), c 10.036(2) A, β 90.11(3)°, V 1005.8(7) A 3 , and Z = 1. Electron microprobe analyses give (average of eight with ranges): Na 2 O 14.28 (10.38–18.55), K 2 O 1.10 (0.51–3.07), CaO 0.04 (0.01–0.11), MnO 0.02 (0.00–0.09), BaO 0.09 (0.00–0.44), FeO 0.02 (0.00–0.07), Al 2 O 3 26.89 (25.71–28.96), Nb 2 O 5 0.04 (0.00–0.10), SiO 2 46.71 (42.65–49.32), TiO 2 0.00 (0.00–0.02), H 2 O 10.73 (10.22–11.22) (determined by crystal structure analysis), total 99.92 wt.%. The empirical formula, based on the crystal-structure analysis and ideally showing 16 (Si + Al) and 32 O atoms in the framework and 7.3 H 2 O groups is: (Na 5.650 K 0.286 Ca 0.009 Ba 0.007 Mn 0.003 Fe 0.003 Nb 0.004 ) ∑5.960 (Al 6.468 Si 9.532 ) ∑16 O 32 ·7.3H 2 O + (O 0.67 ). Garronite-Na is biaxial positive, α = 1.489 ± 0.001, β = 1.492 ± 0.001, γ = 1.496 ± 0.001, 2 V meas. = 75(3)°, 2 V calc = 82(7)°. The strongest eight reflections of the X-ray powder-diffraction pattern [ d (obs.) in A ( I ) ( hkl )] are: 7.098 (79) (011, 110), 5.026 (32) (002, 200), 4.101 (77) (112, , , 121), 3.172 (013, 031, 130, 310), 2.904 (14) (, 222), 2.685 (64) (123, ), 1.9669 (14) (015, , 341, 510), 1.7213 (11) (, 053, 350, 433). The Mohs hardness is ∼4; D (meas.) = 2.19(2) and D (calc.) = 2.071 g/cm 3 . The structure has been refined to an R index of 0.056 for 2952 unique, observed reflections. The structure is a Si/Al–O framework like that of gismondine with Na atoms and H 2 O groups in the cages.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
