| Research Abstract |
Time-domain IP method is an explorationmethod to find metallic ores by utilizing IP effect obtained from transientchange of observed electric potential. Data analysis program to estimate time constant andfrequency exponent from transient electric potential was developed. As a result of numerical experiments, it was found that characterization of metallic ores is possible by comparing the time constant and frequency exponent of ore bodies.
