| | 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 carried out an IP survey at the Kamaishi mine that produces the iron ore containing lots of magnetite. The IP measurements were done in the iron ore area and the granite area. We got rock samples from the two areas and measured the complex resistivities of them. This paper mainly reports the difference in IP anomalies of iron ore and granite. |
