Abstract
Abstract New monazite U/Th‐Pb petrochronological data from the Annapurna region of central Nepal outline a protracted thermal history spanning ~ 30 Ma from the early Eocene ( c . 48 Ma) to the early Miocene ( c . 18 Ma). Rare earth element data collected concomitant with the isotopic analyses are consistent with prograde metamorphism and crustal thickening between ~ 48 and 30 Ma and anatexis between ~ 28 and 18 Ma. The timing of metamorphism recorded in these rocks is consistent with records of crustal shortening derived from ultrahigh‐pressure rocks in the western Himalaya and exhumed metamorphic rocks in southern Tibet. Although previous records of early shortening/metamorphism related to the initial collision of India with Asia are spatially associated with the northern margin of the Indian plate, the ages presented in this study extend that early record south into the main Himalayan range. These new data provide important geological constraints on this early, poorly documented history.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
