【摘要】 本文在分析区域重磁场的基础上，由重磁资料结合深部地震和大地电磁测深资料所得的莫霍面、居里面、磁性体顶面及上地幔低阻层顶面深度，探讨我国南方地区的岩石圈和地壳厚度变化以及地热构造和基底构造特征，从而阐述了全区各层次的深部地质构造特征。更多还原

【Abstract】 Based on the analysis of regional gravity and magnetic fields, and combined with deep seismic and MT informations, the depths of MoHo, Curie face, magnetic layer top and low resistance layer top of upper mantle can be obtained. Furthermore, different deep structral characteristics of litho- sphere, crust, geothermal and basement structures in south China are discussed.更多还原
