Study on Multifunctional Electromagnetic Prospecting Technology in Mineral Exploration

摘要

Multifunctional electromagnetic prospecting technology, include the time domain induced polarization (TDIP), the artificial source phase induced polarization(RPIP), the natural field audio magnetotelluric sounding(AMT),the controlled source audio magnetotelluric sounding(CSAMT),etc. They form a kind of multi-parameters electromagnetic prospecting technology from shallow to deep . The method have characteristics such as high-resolution, diversified-means, bigger-detection-depth etc, can obtain the electrical parameters of apparent resistivity, apparent polarization, phase, so it can reflect the electrical characteristics of the geological structure and rock & ore to provide information for deep or concealed mine. This overview just summarized achievements made in methods and techniques, basic principles, technical characteristics, applications cope and conditions, case study and results, in hope of giving some guidance for metallic ore exploration.
