GEOPHYSICAL METHODS IN EXPLORATION AND

2004-4-5 · The induced polarization method provides a measure of polarizable minerals (metallic-luster sulfide minerals, clays,and zeolites) within water-bearing pore spaces of rocks. Polarizable minerals, in order to be detected, must presentan active surface to pore water. Because induced polarization responses relate to active surface areas within rocks,disseminated sulfide minerals provide a much better target for this method than massive sulfide deposits, althoughin practice most massive sulfide deposits have significant gangue and have measurable induced polarization. Inducedpolarization has found its greatest application in exploration for disseminated sulfide ore, where it may detect as littleas 0.5 volume percent total metallic luster sulfide minerals (Sumner, 1976). In geoenvironmental studies, inducedpolarization surveys are principally used to identify sulfide minerals,
