| Abstract: | In this paper,the method of compressed mass based on the inversion of 1/500,000 gravity data is used to estimate the crustal structure of Lower Yangzi (the southern part of Jiangsu). The characteristics of deep structure and zoning are approached. It emphasized on the following aspects.The basic configuration and characteristics of crustal structure; The relationship between deep-seated crustal structure and the distribution of earthquakes in the region. |
