摘要
本文根据对海城地震区三条深地震测深剖面资料的综合解释,获得了该震区似三维空间内的地壳与上地幔分层构造与速度分布特征.特别有意义的是:确定了壳内低速层及局部上地幔隆起的似三维分布形态,进而探讨了它们与地震的相关性.
In this paper, The Characteristics of quasi- 3D layered structure and the velocity distribution of the crust and the upper mantle have been obtained in Haicheng Seismic area according to the synthetic interpretation of DSS data from three profiles in the area. Most significant, the form of quasi- 3D distribution of the low velocity layer in the crust and the Iocat convex of the upper mantle has been determined Furthermore, corresponding relationship with earthquake is also discussed.
