8.2 電気探査による硫黄島の地下構造 (II)

抄録

Electric surveys were performed along four survey lines by three methods such as apparent resistivity by dipole-dipole, array, spontaneous potential and frequency effect of induced polarization in the island of volcano, Iwo-jima. It is concluded that combination of those methods is effective to survey complex geologic structure, convection of hydrothermal fluid and distribution of alteration zones in volcanic and hydrothermal areas.
