Abstract
Seismic tomography across the Altyn Tagh fault, at the north edge of t he Tibetan Plateau, reveals a Low P-wave velocity anomaly below the fa ult down to 140 kilometers. This anomaly probably reflects strike-slip shear in the lithosphere. Slip-partitioning may also induce a wedge o f crust from the Tarim Basin to plunge into the mantle.
