Abstract
HighlightsOur September issue includes a new feature for CJMP, short communications, this time a practical contribution on "Picture-Perfect Petrography: Affordable Thin-Section Scanning for Geoscientists in the Digital Era" from Derek Leung and Andy McDonald.Additional short comms.are in the pipeline.Our research content commences with a cautionary tale on the use of pyrite composition as a prospecting tool for gold mineralization with an example from northern Canada.This encouragingly international issue also features characterization studies of pegmatite-hosted carlosbarbosaite, a critical metal-bearing (U and Nb) pegmatite mineral from Argentina, and stibiotantalite (Sb and Ta) from China.A pentavalent U-bearing mineral, shinkolobweite, has been described from the Democratic Republic of Congo, and a new platinum alloy mineral, sidorovite (PtFe 3 ), reported from Russian placer deposits.In addition, Louis Cabri and Andy McDonald strike borishanskiite and platarsite, two platinum group metal alloys, off the list of accredited mineral species; the former reverts to polarite (PdPb), and the latter to S-rich sperrylite.So edit your databases, manuscripts, and holiday greeting cards accordingly.
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.

Full frame machine prediction
Teacher imitationNot 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.
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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
