Abstract

fetched live from OpenAlex

The eudialyte group of complex Na, Ca, Zr silicates encompasses a wide range of compositions in which all the main elements Si, Zr, Ca, Fe and Na vary, and many relatively minor elements such as Mn, REE, Sr Nb, K, Y and Ti are present. For most members of the group the empirical formula is Na15[M(1)]6[M(2)]3Zr3[M(3)](Si25O73)(O,OH,H2O)3(Cl,F,OH)2 and the best method of formula calculation is on the basis of 29 (Si, Al, Zr Ti, Hf, Nb, W, Ta) apfu (Z = 3), which are the elements assigned to the Zr, M(3) and all Si sites in the structure. The commonest substitutions are found with the solid solution series eudialyte sensu stricto (enriched in Si, Ca, Fe and Cl) and kentbrooksite (enriched in Nb, REE, Mn and F), but recent studies show that the series extends beyond kentbrooksite to an exceptionally Ca-deficient eudialyte now named oneillite. Most eudialytes are trigonal R3m or R3m but oneillite is R3. Additional members of the group are khomyakovite and manganokhomyakovite.

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.
