METHOD USING INDUCED POLARIZATION FOR ORE DISCRIMINATION IN EMINATED EARTH DEPOSITS

摘要

A METHOD USING INDUCED POLARIZATION FOR ORE DISCRIMINATION IN DISSEMINATED EARTH DEPOSITS A method for establishing data related to the complex resistivity of selected subsurface earth deposits whereby increased discrimination and identification of ore deposits is established. The method utilizes induced polarization in the earth with establishment of both time domain and frequency domain data and correlation of such data with an analog equivalent circuit of the earth section to derive a value closely approximating the complex resistivity of the selected earth substructure thereby to provide more discriminating data enabling determination of the percentages and types of sulphide ore deposits.
