A comparison on deep structure and spreading evolution between South China Sea and Labrador Sea
Bibliographic record
Abstract
The deep seismic surveys over the extinct ridge of central sub-basin of South China Sea(SCS) are critical for understanding the evolution and geodynamic mechanism of SCS.In this article,the interior crustal structure of the extinct ridge in the Labrador Sea was reviewed and compared it with the SCS in several aspects,then the preliminary understandings was obtained about the formation and mechanism of extinct ridges.The results showed that both extinct seas belonged to slow-spreading ridges.their formation processes were controlled primarily by tectonism other than by magmatism,and their crustal structures showed high similarity.Ridge jump occurring in both of Labrador Sea and SCS,indicated significant tectonic events during spreading process.Both seas having nonvolcanic asymmetric continental margins,suggested that the extension of lithosphere played a more important role comparing with magmatic activities in the initial spreading stage.This research should provide important ideas and evidences for future studying of the crustal structures and geological interpretation for the extinct ridge in the central subbasin of SCS.

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.
