Abstract

fetched live from OpenAlex

Abstract A variety of mushroom tourmaline from the Kat Chay mine, Momeik, near Mogok, Shan state, Myanmar, consists of a black-to-grey single-crystal core from which a single prismatic crystal reaches to the edge of the mushroom, forming a slight protuberance. The rest of the mushroom (∼50% by volume) consists of extremely acicular sub-parallel crystals that diverge toward the edge of the mushroom. The acicular crystals are dominantly colourless to white, with a continuous black zone (2 mm across) near the edge, and pale pink outside the black zone. The composition varies from ∼Na 0.75 Ca 0.05 (Li 0.80 Al 0.70 Fe 1.10 .Mn 0.30 Ti 0.10 )Al 6 Si 6 (B0 3 ) 3 O 18 (OH) 3 (OH,F) at the base of the mushroom to ∼Na 0.60 Ca 0.06 (Li 1.00 Al 1.98 Fe 0.02 )Al 6 (Si 5.35 B 0.65 )(BO 3 ) 3 O 18 (OH) 3 (OH,F) close to the edge at the top of the mushroom. The principal substitutions are: (1) Y Li + Y Al -> y Fe * + y Fe * and (2) T B + y Al -> Si + y Fe * , but there are five other minor substitutions that are also operative. There are six significant compositional discontinuities at textural boundaries in the mushroom, suggesting that the changes in habit are driven in part by changes in external variables such as T and P , plus possible involvement of new fluid phases.

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.
