摘要：

Seismic tomography is used to determine three-dimensional velocity structure of the Dabie-Sulu orogen in eastern China. The high resolution image of the P-waves velocity structure is obtained for the uppermost mantle to a depth of at least 150 km, along the latitudes of 30 degrees -38 degreesN and longitudes of 114 degrees -122 degreesE. Results of this inversion reveal a slab-like high velocity anomaly under this orogen in the depth from Moho discontinuity to at least 110 km. It may represent a remnant of the subducted Yangtze block during the period of Triassic continent-continent collision.
