用激电时间谱视参数评价激电异常的应用效果

THE EFFECT OF APPLYING IP TIME SPECTRUM APPARENT PARAMETERS TO THE APPRAISAL OF IP ANOMALIES

在四个已知区利用时谱激电法，反演求取Ｃｏｌｅ－Ｃｏｌｅ模型视参数，综合考虑ηｓ、τｓ、Ｃｓ参数的作用，全面地研究埋藏极化体的激电特性。根据应用成果，阐明在三维地电条件和存在极化围岩情况下，可以评价激电异常，即能指明具有找矿意义的异常。

In four known areas, time spectrum IP method was used to evaluate apparentparameters of Cole-Cole model by means of inversion and, through an integrated considerationof the function of ηsηs and Cs parameters, the IP Properties Of the buried polarized bodieswere studied comprehensively. According to the application achievements, it is shown thatunder the condition of three-dimensional terrestrial electricity and polarized wall rock, IPanomalies can be appraised, i. e., anomalies with ore-prospecting significance can be pointedout.
