Abstract

fetched live from OpenAlex

Abstract New petrographic and mineral chemistry data are presented to show that the Majhgawan and Hinota pipes are olivine lamproite lapilli tuffs and not kimberlites as suggested elsewhere. These bodies, therefore, comprise a newly recognized province of diamondiferous olivine lamproites. Other intrusions in India have been proposed in the literature as being lamproites or kimberlites. Available information for these localities is discussed and, where possible, augmented by new data (Wajrakarur/Lattavaram, Angor, Jungel, Chelima). The Wajrakarur/Lattavaram bodies are classified here as kimberlites. Although two of these bodies appear to be extreme varieties they do not represent a different rock type and are not lamproites. The Chelima and Gondwana coalfields dyke swarms could include lamproites. There are no data to support suggestions of other lamproites or kimberlites in India. This study highlights the need for further detailed petrological investigations of many of these localities.

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.
