Chromite Crystal Structure and Chemistry applied as an Exploration Tool
Bibliographic record
Abstract
The spinel group minerals have long been of interest to the geosciences due to their use as indicator minerals. Unit cell is a structural measure controlled by composition but is also affected by pressure and temperature relations through order-disorder. This study attempted to look at the applications of unit cell in exploration. The implementation of µXRD for this purpose required the creation the Slice Integration Technique to improve signal over background. Compositions of binary spinels can be approximated through their correlation with unit cell. Possible applications include gemology and curatorial studies, where the nondestructive nature of µXRD is highly advantageous and kimberlite vs non-kimberlite discrimination. The analysis of an indicator mineral was conducted using a field portable XRD and could determine isostructural grains in a field setting or unit cell could be used in the field in conjunction with other new field-portable technologies.

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.
