Abstract:Using high resolution refraction and wide-angle reflection/refraction integrated seismic detection method, deep structural exploration is carried out at Huangyan, Linhai, Dongyang, Tonglu and Changhua in the central part of Zhejiang province. A velocity structure section with a length of about 350 km is obtained. The results show that the crustal structure has obvious multi layers, with three velocity discontinuities, and the velocity structure image reveals the heterogeneity of velocity structure in the basal lateral. This heterogeneity corresponds to the tectonic unit in the boundary or fracture tectonic belt, and also reflects the differences between east and west tectonic characteristics.
