摘要
根据新—甘地震测深结果,以纵波为主,建立了剖面内地壳速度结构模型,结合横波资料对地壳结构进行了研究。确定出超壳断裂14条;划分出一级构造单元4个;二级构造单元8个。从而,对大地构造和地壳演化提出新的认识,为深入研究区内基础地质具有重要意义。
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.
