Kampf, S.J. Mills, B.P. Nash, B. Thorne and G. Favreau (2016) Alfredopetrovite, a new selenite mineral from the El Dragόn mine, Bolivia. European Journal of Mineralogy, 28(2), 479–484. Alfredopetrovite (IMA 2015-026), ideally Al2(Se4+O3)3·6H2O, is a new selenite mineral from the El Dragόn mine, Antonio Quijarro Province, Potosi Department, Bolivia. The mine exploited a telethermal deposit consisting of a single selenide vein hosted by sandstones and shales. The main primary mineral is a Co-rich krut’aite–penroseite. Clausthalite, petrovicite, watkinsonite, eldragόnite, and grundmannite were crystallized from later solutions. Alfredopetrovite is a secondary mineral and occurs in vugs in a krut’aite-penroseite-dolomite-goethite matrix. Other closely associated secondary minerals are: ahlfeldite, allophane, calcite, chalcomenite, favreauite, felsőbanyaite, malachite, and molybdomenite. Alfredopetrovite forms colorless to blue (transmit chalcomenite color) drusy/scaly coatings and compact balls up to 0.5 mm. Individual crystals are up to ~0.1 mm. Crystals are transparent with a white streak and a vitreous luster. The mineral is brittle with a smooth curved fracture and no apparent cleavage. Mohs hardness is 2½. The density was not measured because crystal fragments are virtually invisible in density liquids; D calc = 2.504 g/cm3. Alfredopetrovite is optically uniaxial (+), ω = 1.554(2), and e = 1.566(2) (white light); non-pleochroic. The average of 3 electron probe WDS analyses [wt% (range)/wt% normalized to 100%] is: …

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.
