摘要
多年以来,激发极化法被广泛应用于金属矿产勘探的普查、详查和异常评价工作当中,比较明显的激电异常总是与岩(矿)石中存在电子导体的石墨或金属矿化有密切关系。为了突出与金属矿化关系密切的激电异常、压制干扰因素影响,引入了视金属因素参数来提取激电异常的二次信息,通过应用实例论证,该激电参数二次信息能够较好地评价激电异常,对推断解释有一定的指导作用。
Over the years,induced polarization（IP）method was widely used in the work of metal mineral exploration,detailed investigation and abnormality evaluation,which is always a closely related to the obvious IP anomaly with the rock（ore）containing graphite or metal mineralization.To highlight the metal mineralization closely related with IP anomaly and to suppress the interference factors,people introduce the metallic ratio parameter to extract the secondary information of IP anomaly.This could evaluate the IP anomaly better and has some guidance for inference and interpretation.In this paper,the authors use the metallic ratio parameter in an example of specific job for a detailed discussion.
