Electrical Conductivity of Rocks in the Plate

Abstract

Electrical conductivity structures in the earth were obtained by various Electro-Magnetic (EM) sounding methods. Accordingly, we can estimate the properties of rock, tectonics, and physical conditions of the plates. However, a lack of laboratory measurements of electrical conductivity makes evaluations of the results of these soundings difficult. To interpret the conductivity structures of plates, we should consider every possible parameter that affects the electrical conductivity of rocks. In this paper, I emphasize the importance of combining results of EM soundings and those of laboratory measurements. However, careful laboratory measurements under in-situ conditions are not yet sufficient. Therefore, laboratory work on the electrical conductivity of rocks should be encouraged extensively in order to comprehend the plate
