Abstract

fetched live from OpenAlex

Cavities in two texturally and genetically distinct clasts of the Kaidun meteorite were found out to contain crystals of distinct morphology, but of a similar composition. Cavities in chondrite breccia #d3A contain thin (<4 μm) elongated (up to 25 μm long) crystals that grew perpendicular to the walls of the cavity. The walls of the cavities in partly fused clast #d(3–5)D are covered with clusters of acicular crystals. In both clasts, the crystals are covered by films of phyllosilicates and always have a composition approximated by the formula (Mg,Fe,Mn) 5 Al 2 O 8 · n H 2 O. No mineral phase of this composition has ever been found in nature. The genesis of the mineral phases in the cavities is thought to be related to the crystallization from a fluid of similar composition. The fluid was produced during the cooling of the melt that produced clast #d(3–5)D. The unusual composition of the crystals testifies that this fluid had an unusual composition. This can be explained by the unique nature of clast #d(3–5)D, for which there are good reasons to propose a Martian origin.

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.
