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 η_sη_s and C_s 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.
