Abstract
Abstract New U–Pb calcite geochronological analysis of shear veins in specimens collected from the summit pyramid of Mount Everest demonstrate that upper crustal deformation recorded in those rocks is Himalayan in age and was ongoing at 45.0 ± 5.4 Ma. This deformation precedes movement along the adjacent Qomolangma detachment by ~30 Myrs and coincides with metamorphism in nearby, structurally deeper, sillimanite‐migmatite gneisses and eclogite. The coeval record of deformation and metamorphism across all crustal levels further coincides with detachment of the Indian oceanic lithospheric slab, the inferred “main” collision and final closure of the Tethys ocean in multi‐collisional models of the Himalaya, and Eocene reorganization of tectonic plates in the South Pacific. This new dataset confirms that the summit rocks from Mount Everest preserve not only a complex, multi‐deformational record of Himalayan orogenesis, but also large‐scale changes in plate tectonics.

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
