Abstract
In our March issue, we feature eight brand new minerals; just when you'd finished memorizing the existing list!Find out about alterite and magnesioalteraite (oxalate minerals from Arizona, USA), perchiazziite (a rosasite-malachite group mineral from Italy), four new minerals from the Redmond Mine, North Carolina, USA (two thiosulfates, and two OPb 4 -chain-based minerals), and finally ronpetersonite (BaWO 4 ) from Canada's Yukon, named for the very same Ron Peterson we featured in a special thematic issue of the CJMP in July 2023.In addition, we learn about the exploration implications of columbite-group minerals from the Chinese Altai, inclusions in placer Pt-Fe alloys in Ecuador, hollow bulbous gypsum structures reported from Alberta (Canada), and clarification on the status of the mineral testibiopalladite (PdSbTe); spoiler alert: it's a Sb-analogue of michenerite, but a valid mineral in its own right.In addition, we feature regional geology, in the form of a study of the tectono-metamorphic evolution of the Kluane Schist, from the northern cordillera of the Yukon.Our recently most-read publications, according to GeoScienceWorld, include the following: Still number one, Growth and Stability of Stratiform Carrollite (CuCo 2 S 4 ) in the Tenke-Fungurume Ore District, Central African Copperbelt, by Bjorn Von Der Heyden, Jeffrey Dick, Ryan Rosenfels, Luke Carlton, Kristina Lilova, Alexandra Navrotsky, Tamilarasan Subramani, Brian Woodfield, and Alexis Gibson, in vol.62 (1).Running neck and neck in second place are a pair of tourmaline papers: Trace Element Characteristics of Tourmaline in Porphyry Cu Systems: Development and Application To Discrimination and Recognizing Tourmaline in Mineralized Porphyry Cu Systems: Textures and Major-Element Chemistry, both papers by Christopher Beckett-Brown, Andrew McDonald, and Beth McClenaghan, and featuring in 2023's volume 61, issue 1.After them, we find, already working up the charts like a Beyoncé country hit, in spite of its release only in late March 2024, Types and Evolution of Columbite-Group Minerals from Pegmatites in the Chinese Altai, NW China: Implications for Regional Petrogenesis and Rare-Element Mineralization by

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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
