摘要
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.
