中文摘要：

本文利用CSAMT方法对相山石洞地区进行了深部地质结构探测.并尝试借助于先进的专业软件平台Oasis montaj对研究区已有的重磁数据生成3D重磁地球物理模型,从重磁模型中切取与实测CSAMT剖面大小、位置一致的密度切片和磁化率切片.将实测CSAMT剖面与密度切片和磁化率切片共同应用于解译石洞地区的深部地质结构.研究结果表明：CSAMT法较清晰的划分出了该地区的主要岩层的组间界面,刻画出了岩性界面的起伏形态,且与重磁资料共同识别出了3条已知断裂以及推测出了1条隐伏断裂;通过充分利用已有的重磁数据,不仅可以为CSAMT的地质解译提供依据,还可以提高地球物理数据的利用率降低地质工作的勘探成本.

英文摘要：

This paper uses the CSAMT method to detect deep geological structure. of Shidong area in Xiangshan. Trying to generated 3D geophysical model of gravity and magnetic with the aid of advanced professional software platform Oasis montaj,from the models we have achieved the slice of density and susceptibility which consistent with the size and position of the CSAMT profile.And then the CSAMT profiles and slice of density and susceptibility are all applied to interpret the deep geological structure of Shidong area. The results showed that the CSAMT method have successed divided the boundary of different groups,depicted the form of the lithologic interface,and together with gravity and magnetic data they indentified 3 known faults and predicted a buried fault. By fully use of the data of gravity and magnetic which we had,it can not only provide the basis for the geological interpretation of CSAMT profiles,but also can improve the utilization rate of geophysical data to reduce the exploration cost of geological work.
