Transform Tectonic Node of the Middle and Lower Reaches of the Yangtze River and Analysis of Regional Metallogenic Settings
Bibliographic record
Abstract
East China,which had experienced frequent crustal movement,complex tectonic evolution,intense magnetism,and diverse mineralization since the Mesozoic era,is an important area in various tectonic regime transform.The Middle and Lower Reaches of the Yangtze River is a typical area where the tectonic system converted from Mesozoic Tethys tectonic regime to the Pacific tectonic regime.It is a focal point of the two tectonic regimes met and transformed,with the relationship between spatial and temporal evolution of lithospheric material reorganization and structural reconstruction.The structural knots of the Middle and Lower Reaches of Yangtze River were the result of tectonic regime transition between Tethys and Pacific tectonic regimes in eastern China,The Dabie Orogenic belt,Tan-Lu Faulting belt,and Middle-Lower Reaches of Yangtze River metallogenic belts directly recorded the transition process of the two tectonic regimes,spatial-temporal relations between deposition-tectonic-magmatic-metallogenic and dynamic setting.The Middle and Lower Reaches of Yangtze River structural knot has distinct regularity of structural overlapping.The magmatic activity and the distribution of the metallogenic belt along the Middle and Lower Reaches of the Yangtze River area are controlled strictly by NE-SW trending structural belt represented by Yangtze River compound structural belt and NW-SE trending structural zones represented by Tongling-Hangzhou structural belt.Node-type mineralization can be found within the structural knots of the Middle and Lower Reaches of Yangtze River.Therefore,the intersection positions between various-scale NE-SW trending structural belts and NW-SE trending structural belts are the locations of ore concentration areas and important deposits.

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.
