| Abstract: | The model of crustal velocity structure was established and the crustal structure was studied in the Gansu-Xinjiang section based on the data of deep seismic sounding, mainly of longitudinal wave. The analytic results show for-teen fractures cutting across the crust with four priliminary structural units and eight secondary structural units. Thus, the research presents new knowledge about geotectonics and crustal evolution, and has an important significance on the furture intensive study in this area. |
