Canadian Mineralogist Yol.X, pp. 173-180 (1989) CLUSTER ORDERING AND ANTIPHASE DOMAIN BOUNDARIES IN HAUYNE
Bibliographic record
Abstract
High-resolution transmission electron microscopy indi-cates-ordering of [Na3Ca'SO4]3+ and [K2Ca'OH]3+ clus-ters in hauyne, ideally Na6Ca2tAl6Si6Ozl(SO4)2. Reflec-tions oftype&i l, I: 2n + l, indicatethat space groupP43r is an average for hauyne, and that space group P23, a subgroup of P43n, applies for each domain, as was found in nosean andlazurite. Antiphase domainboundaries, aris-ing from ordering of the clusters, occur in hauyne. In general, diffraction patterns of sulfatic sodalite samples show complex satellite reflections in several directions that arise from well-defined modulations of the framework oxygen-atom positions; in tle sample of hauyne that was studied here, however, diffuse streaked reflections instead of satellite spots occur in directions such as <001>' <110>, and <112>. The diffuse, streaked reflections mark the beginning of superstructure formation. Some parts ofthe crystal show superstructure fringes, and others do not, thus indicating anotler type of domain structure. The ordering of the cage clusters does not significantly affect the positions of the framework oxygen atoms ' sug-gesting that [Na3Ca'SOa]rn and [K2Ca'OH]r * clusters give rise to similar geometrical effects. Contrary to previous work, this study indicates an incomplete nosean-haulne solid-solution series.

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.
