大功率激发极化法在西藏某金铜矿区的应用

The Application of the large power induced polarization method in a goldcopper mine of Tibet

本文阐述了激发极化法在西藏某地金铜矿矿区的应用,通过在勘查区内早期路线地质调查成果,选择时间域大功率激电中梯和时间域激电测深方法,发现了四个激电异常,依据勘查区内岩矿石的物性特征,对极化体特征进行了解释推断,经钻探验证,发现了多条金铜矿体。

In this paper, the writers introduce the application of the large power induced polarization method in a gold-copper mine of Tibet. According to the geology survey results in the exploration area, we choose the IP intermediate gradient and IP sounding method of time domain, and found four IP anomalies. On the basis of the physical characteristics of the rocks and minerals, extrapolate the polarized object features. And found several gold-copper ore body by using drill-hole exploration.
