Petrogenesis of Proterozoic Lamproites and Kimberlites from the Cuddapah Basin and Dharwar Craton, Southern India: a Reply
Bibliographic record
Abstract
Mid-Proterozoic kimberlites and lamproites from southern India are some of the world's oldest known, small-fraction, volatile-rich, silicate melts that, until recently, have remained poorly documented in the international literature. The main aim of the work by Chalapathi Rao et al. (2004) was to understand the tectono-magmatic processes operating beneath the Dharwar Craton and Cuddapah Basin during the Mid-Proterozoic. To constrain (1) the melt generation processes and (2) the nature of the source regions involved in the genesis of the small-fraction mantle melts it was necessary for us to undertake detailed petrographic descriptions and high-precision analyses of the mineral and bulk-rock chemistry of Dharwar craton kimberlites and Cuddapah Basin lamproites. The main emphasis of the paper by Chalapathi Rao et al. (2004) was not to classify rocks as kimberlites or lamproites, as Anil Kumar & Gopalan (2005) suggest, although this was made possible by results from our detailed mineralogical and geochemical studies.

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.
