| | Abstract | | Exploration of nonferrous metal ore deposits like porphyry copper and iron oxide-hosted copper-gold deposits, the IP method is used in many cases. This is because sulfide minerals such as pyrite and chalcopyrite have the IP effect. However, these sulfide minerals are not often found at the place where the IP anomalies were observed. One of the causes is existence of magnetite. Therefore we examined validity to the SIP methods for distinction with sulfide minerals and magnetite. In this study, we measured the complex resistivities of artificial samples consisting of pyrite or magnetite particles, glass beads and KCl solutions. Then we tried to analyze the SIP parameters by Cole-Cole model. This paper mainly reports the result of complex resistivity measurements of the artificial samples. |
