Fig. 2From: Correlation between induced polarization and sulfide content of rock samples obtained from seafloor hydrothermal mounds in the Okinawa Trough, JapanPhotographs of rock samples and complex conductivities of three typical rock samples: a rock sample KM18-08C #81 R01; b rock sample KM18-08C #84 R04; c cutting plane of rock sample KM18-08C #84R04A. The yellowish stripe structure is made mainly of the chalcopyrite (Cp) and pyrite (Py), together with the matrix mainly occupied by sphalerite (Sp; basically nonconductor); d, e rock core sample KM18-08C #84 R04A_3. A distinct yellowish shape is evident in (e)Back to article page
