摘要
本文介绍由重磁资料计算上海地区居里面、莫霍面、均衡重力异常及地幔流应力场的方法和成果,并在对成果初步分析的基础上,探讨了深部地质构造特征及其与地震活动趋势的关系,其中着重讨论了居里面及其与地震活动的关系。文章最后提出了对上海地区地震活动趋势的几点认识。
This paper presents results of Curie Boundary, Moho, isostatic gravity anomaly and stress field caused by flow in mantle, using gravimetric- magnetic data obtained in and around Shanghai area. And methods of calcu- lation are also given. Based on the preliminary analysis of the results, deep- seated geological structure feature and its relation with seismic active trend are described. Curie Boundary and its relation with seismic activity are dis- cussed. Finally, some opinions about seismic active trend are given.
