Abstract

fetched live from OpenAlex

Abstract Based on magnetotelluric (MT) sounding along the three profiles across the Bangong‐Nujiang suture in Tibet, we have established the electric model for this tectonic zone and adjacent areas and studied the features of the deep structure in this region. The result shows that there exist widespread discontinuous high‐resistivity bodies in upper crust along this zone and its both sides, which reflect spatial distribution of magmatic rocks that exhibits big difference between the northern and southern sides. Beneath the Gangdisê and Qiangtang terranes, middle and lower crust is characterized by extensive high‐conductivity layers, indicative of the sign of underthrusting of the India continent beneath Tibet. Below the high‐conductivity layers is a high‐resistivity block that emanates from the cold and rigid India crust diving northward. The electric structure model of the Qiangtang terrane can be divided into northern and southern parts. In the southern part, the high‐conductivity layer in crust is related with the impeding of the Bangong‐Nujiang tectonic zone to the underthrusting India plate. While in the northern part of Qiangtang, such zone is associated with the hindering of the Asian continent to the India plate as well as the southward subduction of the Asia continent. Because of the impeding of the Bangong‐Nujiang suture and Asian continent, the northward underthrust of India is likely not over the Bangong‐Nujiang suture, instead sinks into asthenosphere nearby the suture, causing upwelling of mantle materials that resulted in channels for exchanges of heat and materials in crust and mantle as well as large‐scale high‐conductivity bodies that extend downward to upper mantle. The electric structure of the Bangong‐Nujiang suture indicates that it is a set of steep and large faults cutting through the crust.

Teacher imitation

Not 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.
