Deep conducting zones in the junction region of the Kurile-Kamchatka and Aleutian island arcs

The main properties of conducting zones in the lithosphere are examined. They are compared with data of the gravitational field, seismology, seismic tomography, and some other geological and geophysical studies. The possible origin of the conducting zones is considered. Their high conductivity is connected with the presence of mineralized solutions and magmatic melts. A rough estimate is given for the concentration of mineralized solutions in these zones. Regions of conducting zones correlating with anomalies of lower P wave velocities are associated with the presence of magmatic melts. An approximate estimate is obtained for the concentration of magmatic melts in the lithospheric zone beneath the Klyuchevskaya group of volcanoes.
