Abstract

fetched live from OpenAlex

Montetrisaite, a new hydroxy-hydrated copper sulfate mineral species from Monte Trisa, Torrebelvicino, Vicenza, in Italy, has chemical formula Cu6(SO4)(OH)10•2H2O. It is associated with galena, sphalerite, chalcopyrite, cerussite, anglesite, oethite,\nlangite, posnjakite, linarite and redgillite. The crystals are blue, vitreous, transparent, striated vertically, with a cleavage, {001}. \nThe diffraction pattern shows strong reflections pointing to an orthorhombic unit-cell with a 2.989(2), b 16.970(5), c 14.812(4) Å, space group Cmc21, Z = 2. The strongest reflections [d in Å(Irel)(hkl)] are: 7.45(100)(002), 3.73(35)(004), 2.788(18)(061), 2.503(14)(132) and 1.595(20)(175). In addition, very weak and diffuse reflections occur, which point to a monoclinic cell with a doubled a parameter. The crystal structure is built up of layers of edge-sharing Jahn–Teller-distorted Cu-centered octahedra, to which single SO4 groups are connected on one side. Between the layers, H2O molecules are located, and the layers are connected through hydrogen bonds. The refined average structure shows sulfate groups and H2O molecules in both their statistically possible\npositions; in the real structure, however, only one half of those positions can be really occupied. The new mineral is structurally related to posnjakite, wroewolfeite, langite, and spangolite. On the other hand, its structure is significantly different from that of redgillite Cu6(SO4)(OH)10•H2O, which has a very similar chemical formula.

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.
