Abstract

fetched live from OpenAlex

Eighty-nine diamonds from the A154 South kimberlite pipe at the Diavik diamond mine, Northwest Territories, Canada, were selected from run of mine production on the basis of morphology and visible inclusions. The diamonds were cut and polished to expose included mineral grains and to allow for imaging of internal structure. Internal zonation of the diamonds was imaged using cathodoluminsence (CL). Included minerals in diamond were analysed in-situ for major element composition using microbeam methods. Diamonds and their inclusions from the Diavik mine have been previously investigated by Donnelly et al. (

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
