Abstract

fetched live from OpenAlex

Based on the OBS data and the multi-channel seismic data collected in 2009 and 2011, the structure of crust in the north part of Southwest Sub-basin in the South China Sea is explored.Using two-dimensional ray tracing method to establish P velocity model,employing acoustic basement reflection,the reflections from the top interface of lower crust and the Moho are calculated in order to give the location of the velocity discontinuity interfaces.By employing refraction under the acoustic basement and the head wave from the mantle,the P wave velocity structure of the entire survey line is pictured.The results showed that the depths of the top interface of lower crust and the Moho vary significantly.We inferred the southwest sub-basin rifting model,and concluded that there is a similarity in geological structure between the southwest sub basin of South China Sea and Iberia Newfoundland which is a typical non-volcanic margin.It is found that the two end-member mechanical continental rifting models could not satisfactorily explain the southwest sub-basin geological structure,while the elastic beam mechanics model can explain this rifting mode.Although in the lower crust of the northern part of southwest sub-basin there isn't large-scale magmatie activity,we inferred that a small amount of molten material may exist on the top of Moho.

Full frame distilled prediction

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.
