该矿区地处豫西,是中原地区的一个大型硫铁矿床。一、地球物理特征岩矿石物性测定结果表明:火成岩类岩石电性为低阻低极化率,ρ值为100~600欧姆·米,η值为1-2%。白云岩及构造角砾岩电性差异不大,均呈高阻低极化率,ρ值为1000~3000欧姆·米,η值为1%以下。各种矿石大都表现出高极化特征,η值为10-20%,但ρ值随矿物富 The mining area is located in western Henan, is a large pyrite deposit in the Central Plains. First, the geophysical characteristics of rock ore physical determination results show that: igneous rock conductivity is low resistivity low polarizability, ρ value of 100 ~ 600 ohm · m, η value of 1-2%. The dolomite and tectonic breccia have little difference in electrical properties, showing high resistivity and low polarizability with ρ values ​​of 1000 to 3000 Ω · m and η values ​​below 1%. Most of the ore shows high polarization characteristics, η value of 10-20%, but ρ value with the mineral rich
