PERMINGEATITE, Cu<sub>3</sub>SbSe<sub>4</sub>, FROM PŘÍBRAM (CZECH REPUBLIC): DESCRIPTION AND RAMAN SPECTROSCOPY INVESTIGATIONS OF THE LUZONITE-SUBGROUP OF MINERALS
Bibliographic record
Abstract
Permingeatite from the Příbram uranium-base metal ore district (central Bohemia, Czech Republic), has been studied in detail. Based on electron microprobe analysis, the empirical formula of the studied permingeatite (mean of 10 point analyses, based on Sb+Cu+Fe+Se+S=8 apfu) is Cu3.00(Sb0.99Fe0.04)Σ1.03(Se3.74S0.23)Σ3.97. The unit-cell parameters refined from powder X-ray diffraction data are a=5.6323(2) Å, c=11.2354(7) Å, with V=356.41(2) Å3 (for space group I42m). The Se-S substitution is characteristic for this permingeatite. The only other element which enters the structure of the luzonite-group minerals in considerable concentrations is Fe. The dominant feature in the Raman spectra of the studied minerals is a suite of spectral bands that corresponds to the stretching and bending vibrations of tetrahedral XY4 (X = As/Sb; Y = S/Se) groups

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
