Deep Crustal Contact Between the Pamir and Tarim Basin Deduced From Receiver Functions

The deep crustal deformation in the east Pamir response to Cenozoic collision with Tien Shan and Tarim Basin is so far poorly constrained. We present new insights into structure of its surrounding regions using P receiver functions from 40 temporary permanent seismic stations. thickness reaches a maximum 88 km beneath central southern decreases sharply 50–60 along 41–50 below Basin. most prominent structures involve double Moho, suggesting eastward underthrusting lower crust Pamir, two Moho offsets, supporting delamination Asian pure shear shortening northeastern margin between
