| Geoelectromagnetic methods for geotectonics, geodynamics, search of deposits and ecology | Modern geoelectromagnetic methods (geoelectromagnetics) allow us to study the distribution of electrical conductivity and hence the structure, composition, temperature and fluid regime of the Earth’s crust and upper mantle by measuring and analyzing the electromagnetic field at the earth surface and from space. Earth's lithosphere consists of stable blocks (cratons) with low electrical conductivity and relatively narrow tectonically active zones of higher conductivity. Geoelectromagnetics is an effective tool for detecting the zones of high electrical conductivity, which serve as a way for the transfer of energy and fluids from deep interior to the surface of the Earth. In particular, the most intense geological processes take place in the active zones of high conductivity and the majority of mineral deposits are found there. The deep geoelectromagnetics gives a chance of resolving debatable issues of plate tectonics, plume tectonics and other geodynamic processes, and is also efficient in prospecting for hydrocarbons. Geoelectromagnetics is also effective tool for studying the uppermost layers of the Earth’s crust, particularly for the underground water prospecting, for the solution of engineering and agricultural questions, in archaeology and in both natural and anthropogenic geodynamic processes monitoring aimed at preventing risks associated with these factors (prediction of earthquakes, volcanic activity, greenhouse gas emissions in mines, etc.). Geoelectromagnetics is a suite of complex high tech tools, but its misapplication can lead to false conclusions and predictions. It is therefore necessary to encourage a professional discussion regarding the contemporary issues of geoelectromagnetics. The purpose of the symposium is to present the most significant geological results obtained by means of geoelectromagnetic methods (GDS, MTS, MVP, active methods with controlled sources), to evaluate the effectiveness of different methods and discuss the geological problems that can be solved efficiently by employing geoelectromagnetics in the future. | Igor Rokityansky, Abdulkhai Zhamaletdinov and Valeriya Hallbauer-Zadorozhnaya |
