摘要
This paper is the second one of a series of three papers on fluid evolution of the crust upper mantle and the causes of earthquakes. Based on the first paper, two conductive mechanisms of the crustal conductive layer(CCL), graphite and supercritical saline aqueous fluids, are discussed. As there are difficulties for graphite model, the supercritical fluids are investigated in this paper concerning the phases, the electrically conductive behaviors, the evolution and the sealing mechanisms of the fluids. It is obvious that this model is reasonable to explain the geophysical and geochemical characteristics of the CCL presented in the first paper.
