Tomographic evidence for the Eurasian lithosphere subducting beneath south Taiwan
Bibliographic record
Abstract
A tomographic image of the crust and upper mantle beneath the Taiwan Island as derived from local, regional and teleseismic data simultaneously revealed a high‐velocity zone from the surface down to a depth of 300 km, locating beneath south Taiwan (to the south of latitude 24°N). We interpret this high‐velocity zone to be the subducted Eurasian lithosphere. Our result is different from a global tomography study that shows the Eurasian plate subducting beneath most part of the Taiwan Island down to 670 km depth. This down‐going model of the Eurasian lithosphere implies that the tectonic framework of Taiwan has been changing from subduction in the south to collision in the north, which provides geophysical evidence supporting the previous proposed models. The subducted Eurasian lithosphere colliding with the subducted Philippine Sea plate would have contributed to the mountain building, active seismicity and crustal deformation in the study region due to the lower part of the Eurasian continental plate subducted beneath south Taiwan.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
