Studies of the state equations of solids at high temperature and pressure indicate that there is a close relation be tween the electrical conductivity of rocks and temperature. Therefore, measurements of deep conductivity can provide knowledge of the present state and temperature of the Earth's crust and upper mantle matter. Infor mation about the temperature of the Earth's interior in the remote past is derived from heat flow data. Experimental investigation of water-containing rocks has revealed a pronounced increase of electrical conductivity in the temperature range D from 500 to 700 DC which may be attributed to the beginning of fractional melting. Hence, anomalies of electrical conductivity may be helpful in identitying zones of melting and dehydration. The studies of these zones are perspective in the scientific research of the mobile areas of the Earth's crust and upper mantle where tectonic movements, processes ofthe region al metamorphism and of forming mineral deposits are most intensive. Thus, in the whole set of research on physics of the Earth the studies of electrical conductivity of deep-seated rocks appear, beyond doubt, very important.

DOWNLOAD EBOOK →Developments in Geotectonics, 4: The Upper Mantle focuses on the upper mantle and its influence on the development of the earth's crust, including history of the moon and other planets and volcanology. The selection first offers information on the origin of the earth, including ideas on the formation process of the terrestrial planets, condensation of dust particles, nature of the earth's core, thermal history of the earth, and fractionation of iron in the terrestrial planets. The text then ponders on the beginning of continental evolution, as well as the oldest rocks of the earth's crust, thermal history of the moon, and early history of the other planets. The text elaborates on magmatic activity as the major process in the chemical evolution of the earth's crust and mantle; trends in the evolution of continents; progress and problems in volcanology; and pressure and temperature conditions and tectonic significance of regional and ocean-floor metamorphism. The manuscript also takes a look at the state of mantle minerals, melting temperatures in the earth's mantle, and geomagnetic induction studies and the electrical state of the upper mantle. The publication is a dependable reference for readers interested in the study of the upper mantle.
