Study on DC Resistivity Induced polarization Method for Prospecting and Detection Technology Based on Numerical Simulation

In order to improve the accuracy of geological interpretation of DC resistivity induced polarization detection results and promote the application of DC resistivity induced polarization in mineral exploration, finite element numerical simulation was used to compare and analyze the main aspects of low resistance and high polarization bodies, vertical plate bodies, low resistance cover layers, high resistance cover layers, surface non-uniform bodies, terrain fluctuations, and inversion interpretation of measured data in DC resistivity induced polarization detection. The research results provide a reference for the interpretation of measured data in DC resistivity induced polarization ore exploration, indicating that for the inversion interpretation results in actual exploration, constructing a geological body model based on abnormal characteristics and conducting finite element numerical simulation can quickly distinguish the abnormal attributes of the detection target body, distinguish virtual and false anomalies, improve the level of quantitative interpretation and the efficiency of ore exploration.
