Ten years of research progress on the structure, <i>P–T</i> path and Fluid–Melt evolution of the deeply‐subducted UHP continental crust in the Sulu belt
Bibliographic record
Abstract
Fundamental scientific questions about the tectonics of continental subduction during collisional orogenesis include: 1) the maximum depth from which the continental crust can be exhumed along the subduction channel, and 2) the evolution and role of fluid and melt in the deformation and metamorphism of the crust during burial and exhumation.To address these questions, we have studied one of the most deeply subducted slabs of continental crust to retrieve information about deformation and metamorphism at extreme pressures.In this presentation we summarize the results of our studies conducted during the past ten years from the Yangkou Bay-General's Hill area in the central Sulu belt.Here we have integrated structural mapping with microstructural, petrological, geochemical and geochronological studies on the most deeply-subducted (possibly >200 km [1] ) UHP metamorphic rocks in the Sulu belt.The rocks preserve evidence of fluid evolution from nominally anhydrous minerals and partial melting during exhumation.Our studies have led to a new understanding of the structural history, P-T-t path and melting of UHP rocks during continental subduction and exhumation associated with collisional orogenesis.

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.
