Abstract
A deep seismic sounding profile located in the western Sichuan and eastern Tibetan region extends from Batang (Zhubalong) to Zizhong, Sichuan. It passes through the Songpan-Garze Fold System and the Longmenshan Tectonic Zone, and ends in the Yangtze Craton. Based on the travel times of phases on the profile, incorporating information on the relevant amplitudes, we determined 2-D P-wave crustal velocity structure along the profile, analyzed the principle differences between the crustal and upper mantle structure in the Western Sichuan Plateau and Sichuan Basin, discussed the deep feature of the major faults on the profile, the tectonic relation between the Yangtze Craton and the Tibetan Plateau and the deep structural environment where strong earthquakes occurred.
