Long‐lasting intracontinental strike‐slip faulting: new evidence from the Karakorum shear zone in the Himalayas
Bibliographic record
Abstract
Terra Nova, 23, 92–99, 2011 Abstract Zircon crystallization ages for a syntectonic granite and an associated dyke along the Tangtse strand of the Karakorum fault are 18.5 ± 0.2 and 18.6 ± 0.2 Ma, respectively. A dyke cross‐cutting the foliation in the Karakorum shear zone (Ksz) yielded an age of 16.0 ± 0.6 Ma. These data show that the Ksz was associated with significant granitic magmatism and was active before 16 Ma, since at least c. 18.5 Ma. Consideration of other data along the Karakorum fault suggests that the fault has most likely been active since c. 22.7–25 Ma at a rate of 8–13 mm a−1. This study conducted in the frontal part of the Himalayan orogen shows that large continental strike‐slip faults can be linked with magmatism and be stable for more than 20 Ma, even in the hottest part of the orogen where strain localization is supposed to be at a minimum.

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.
