Appalachian-style multi-terrane Wilson cycle model for the assembly of South China
Bibliographic record
Abstract
The evolution of South China involved accretion-collision of multiple terranes from the Proterozoic to the Mesozoic. Zircon U-Pb ages, Hf data, and structural data indicate that the Cathaysia block consists of two terranes, West Cathaysia and East Cathaysia, separated by a newly recognized major strike-slip fault. We propose that West Cathaysia was part of a microcontinent that originated from a Grenvillian-aged orogen in the Rodinia supercontinent, East Cathaysia originated from an Indosinian-aged orogen in the Paleo-Tethyan regime to the south and was translated to the east of West Cathaysia through strike-slip motion, and the early Paleozoic Wuyi-Yunkai orogeny was a result of direct collision of West Cathaysia with a yet-unidentified terrane that rifted away after the collision. We conclude that a multiterrane Wilson cycle (multi-terrane accretion-collision, large-scale strike-slip motion, and separation of two terranes by post-collisional rifting along the suture zone) characterizes the history of South China and may be a common feature of orogens.

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.
