中文摘要：

对深部探测地球物理找矿领域中最为常用的CSAMT法的反演技术进行探索。首先利用一维Bostick反演方法进行野外实测数据的反演；由于Bostick反演结果较为准确地确定了探测深度，然后将一维反演断面信息作为二维反演的初始模型断面，利用Occam反演方法进行正则化反演；再进行地质解释，间接地提高了地电断面初始模型的正确度；最后结合东昆仑地区某Cu、Pb、Zn多金属矿CSAMT实际勘察结果，分析总结这种数据处理方法的认知。结果表明，逐级反演技术提高了勘察效果，为今后勘察提供了有益的经验。

英文摘要：

The inversion technique of CSAMT method which is widely used in the field of geophysical prospecting was investigated. Firstly, one-dimensional Bostick inversion method was used in the inversion of data measured in the field; secondly, the cross-section of one-dimensional inversion was taken as an initial cross-section model of the two-dimensional inversion since the probing depth determined by Bostick inversion is relatively accurate, and we Occam inversion method was used for positive inversion; thirdly, geological interpretation was concluded, which improves the accuracy of the initial geoelectric section model indirectly; at last, this data processing method was analyzed and a conclusion was drown while integrating the CSAMT survey results of eastern Kunlun Cu, Pb and Zn polymetallic ore. The results show that step by step inversion technique contributes directly to the survey result, which provides useful experience for future investigation.
