摘要
该区铅锌矿属于硫化物矿种,具有很强的激发极化效应。这里运用EH4电导率成像技术[1]和激电中梯方法[2],结合三十九块岩矿石标本、九种典型地质体露头的物理参数测量分析,综合解释推断铅锌矿化异常一处,矿化异常最终经钻孔证实。这为该矿区外围和深部探矿提供了依据,确定了浙西南找铅锌矿的有效地球物理勘查技术方法。
The lead-zinc ore,which belongs to the sulfide minerals,has a strong induced polarization effect in this area.This paper used two methods,EH4 conductivity imaging technology and IP intermediate gradient mode,based on the measurement and analysis of the physical parameters of 39 rock and ore specimens as well as 9 kinds of geologic bodies′ outcrop,to infer a lead-zinc abnormality comprehensively and forecast the ore bodies around.The mineralization abnormality was ultimately confirmed by drilling,which provides a basis for the mining area perimeter and deep exploration,and establishes an effective geophysical exploration method to find a lead-zinc ore in the southwest of Zhejiang.
