Abstract

fetched live from OpenAlex

Abstract Bariopharmacoalumite, ideally Ba 0.5 Al 4 (AsO 4 ) 3 (OH) 4 ·4H 2 O, is a new mineral from Cap Garonne, France. It occurs in several places within the mine as colourless to pale yellow interpenetrating cubes up to 0.5 mm across. Bariopharmacoalumite is transparent to translucent, with a white streak, has an adamantine lustre and imperfect cleavage on {001}. The Vickers hardness is 234.35 and the Mohs harness is 3.5. Bariopharmacoalumite is isotropic, with n = 1.573 (upper estimate) [calculated from reflectance values at 589 nm using Fresnel Equations]. The empirical formula, based on 20 oxygen atoms, is: (Ba 0.54 Cu 0.03 K 0.01 ) Σ0.58 (Al 3.99 Fe 0.02 ) Σ4.01 (AsO 4 ) 3.00 (OH) 3.85 O 0.15 ·4H 2 O and the calculated density (on the basis of the empirical formula and single-crystal unit cell) is 2.580 g/cm 3 . The four strongest lines in the X-ray powder diffraction pattern are [ d obs (Å), I obs ,(hkl) ]: 7.759, 100, (001); 5.485, 27, (011); 3.878, 27, (002); 4.454, 18, (011). Bariopharmacoalumite from Cap Garonne is cubic, space group P4̄3m with a = 7.742(4) Å, V = 464.2(4) Å 3 and Z = 1. The crystal structure was solved by direct methods and refined to R1 = 0.0705 for 215 reflections with I > 4σ(I) and is consistent with members of the pharmacosiderite supergroup. Data are also presented from zoned bariopharmacoalumite–bariopharmacosiderite crystals found at the Mina Grande mine, Chile.

Full frame distilled prediction

Teacher imitation

Not 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.
