摘要
芦家坪银矿区位于秦岭褶皱系北秦岭褶皱带二郎坪地体中段,目前深部找矿工作未取得明显突破,因此,利用不同方法技术找矿显得尤为重要。文章通过激电中梯和可控源音频大地电磁测深剖面法相结合的手段,并结合实测剖面及钻孔验证,为下一步找矿提供了物探技术支持。根据矿区银矿的物性特征,可有效寻找目标矿体。
Lu jia ping silver mine area is located in the middle section of Erlang Ping geological body in the north qinling fold belt of Qinling fold system.At present,we have not the obvious break through in the deeply prospecting work.So it is very important to use different methods and techniques in mineral exploration.This paper combines the methods of IP intermediate gradient survey and controlled source audio-frequency magnetollurice(CSAMT),Combined with measured section and validation of borehole to model the corresponding mineral exploration,which provides geophysical technical support for further prospecting.According to this physical characteristic of the silver mine,the target ore body can be found effectively.
