Geothermal Fieldís Interaction with Geophysical Fields of Another Nature

Abstract

The energy balance of active lithosphere zones is to a targe extent determined by nonstationary interaction of mechanical (elastic and hydrodynamic), thermal, electromagnetic, and gravitational geophysical fields. Seismic disturbances of electromagnetic and temperature fields, repeatedly observed before earthquakes are a striking manifestation of this interaction (Sec. 1). Technological processes of exploitation of hydrothermal deposits are determined by the interaction of hydrodynamical and temperature field (Sec. 2). These ìfastî interactions (with the characteristic time scale from seconds to years) take place against the background of ìslowî thermomechanical interactions (time scale of Myears), the latter determining the formation of regional geothermal fields (Sec. 3).
