苏浙皖区地壳结构的深部轮廓笔者曾作过专题研究。滕吉文等根据爆炸地震资料解释马鞍山—启东剖面由五层介质组成.本文以N层变密度法将该区地壳-上地幔顶部进一步区分为“七面八层”。根据重力资料初次发现了与壳内低速层一致的中地壳低密层、上地 Jiangsu, Zhejiang and Anhui provinces crustal structure of the deep outline of the author had made a special study. Teng Ji-wen et al. Interpreted Ma’anshan-Qidong section as a result of the explosion seismic data, which is composed of five layers of media.This paper further divides the top of the crust-upper mantle in the area into “seven layers and eight layers” by the N-layer densification method. According to the gravitational data for the first time found in the same low-velocity layer of the crust in the lower crust, on the ground
