激电中梯及音频大地电磁测深法在青海德龙金矿床的应用

Application of IP intermediate gradient survey and controlled source audio-frequency magnetotellurice (CSAMT) in Delong gold deposit,Qinghai

东昆仑东段德龙金矿主要受断裂构造控制,文章选取德龙金矿04勘探线为研究对象,采用激电中梯和音频大地电磁测深相结合的方法,提取地球物理找矿信息,为测区提供更大勘探深度的电性资料,并推测了一条断面上的构造蚀变破碎带,以期为下一步找矿工作提供参考依据。

The eastern section of East Kunlun Delong gold deposit is mainly controlled by faults. At present,the prospecting effect is not good,so we need to strengthen the exploration of the deep in order to get a breakthrough in prospecting. This paper selects the exploration line 04 in Delong gold deposit as the research object,using the IP intermediate gradient survey method combined with controlled source audio-frequency magnetotellurice to search geophysical prospecting information. The purpose of this study is to provide the electrical data of the greater exploration depth in the survey area,and to speculate on the structural altered fracture zone on a section.
