Tait, V. Dicecco, N.A. Ball, F.C. Hawthorne, and A.R. Kampf (2014) Backite, Pb2Al(TeO6)Cl, a new tellurate mineral from the Grand Central Mine, Tombstone Hills, Cochise County, Arizona: Description and crystal structure. Canadian Mineralogist, 52(6), 935–942. Backite (IMA 2013-113), ideally Pb2Al(TeO6)Cl, is a new tellurate mineral discovered at the Grand Central mine located ¾ mile south of Tombstone, Arizona, U.S.A. Oxidized Ag- and Au-bearing galena and minor copper and zinc ores occur in faulted and fractured parts of a dike, and in brecciated footwall zones of the dike. Backite forms dark to pale blue-gray rosettes up to 0.15 mm consisting of hexagonal plates up to 0.08 mm exhibiting the forms {100}, {010}, and {001}. The rosettes are perched on microcrystalline quartz and associated with schieffelinite, oboyerite, rodalquilarite, cerussite, jarosite, and a new Pb-Cu tellurate-sulfate. Backite is moderately transparent with opacity increasing with intensity of color, has a very pale bluish-gray streak and adamantine luster. It has a perfect micaceous cleavage on {001}, is brittle with a splintery fracture and has a Mohs hardness of ~2–3. The density was not measured due to the lack of material; D calc = 5.573 g/cm3. The mineral does not fluoresce under UV light. Backite is optically uniaxial (−). The indices of refraction are greater than 1.80. Available liquids with higher refraction were reacting with the mineral; n calc = 1.878. Backite is pleochroic with O = …

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.
