摘　　要：高密度电法系统(SUPER STING R8 IP)观测可以同时得到电阻率与极化率的数据.根据电阻率异常对隐伏构造、地质体的产状规模进行推断,根据视极化率异常对隐伏矿体的特征及赋存位置与构造的关系进行推断,利用其结果可进行异常圈定,为进一步勘查指明方向.同时在森林覆盖区使用该方法可有效减少植被破坏,解决环境保护与区域矿产勘查的矛盾.The multi-electrode resistivity and induced polarization （IP） survey can obtain resistivity and polarizability data at the same time.The concealed structures,occurrence and scale of the geological bodies can be inferredby the resistivity anomalies.The features and geometry of the concealed orebodies as well as theirrelationship with structures can be inferredfrom thepolarizability anomalies.Theresults can be used to delineate anomaly and guide the future work.In forestcovered area,this method can reduce the vegetation destroy,therefore solvethe conflict between environmental protection and mineral exploration.
