摘要
在胶东夏甸金矿控矿断裂构造的勘探中,根据区域地质背景、构造及岩性分布情况,研究了两条CSAMT(可控源音频大地电磁法)测深剖面,查清了研究区内主要成矿带——招远—平度断裂的实地位置,并在重点异常区域布设了验证孔,钻孔打到断层泥以及蚀变带,推测该异常是由于断层活动使岩石破碎蚀变后,岩层电阻率明显降低而引起的.
In the exploration of the Xiadian gold deposits in Jiaodong,according to the regional geological background and lithologic distribution,two CSAMT profiles is carried out,and the actual location of the main metallogenic belt,Zhaoyuan to Pingdu fracture area,is identified.And then,verify holes in key anomalie area are designed.The fault gouge and alteration belts are found through drilling.Combined with the related geological data,it is inferred that the anomalies is due to the rock resistivity significantly reduced after rocks fractured and alteration for activity of faults.
