The results of application of the frequency-resonance technology of remote sensing data processing within the search areas in Mongolia, Nevada (USA), Turkey and Ukraine are analyzed. Anomalous zones of the "thermal water" type have been found at all survey areas, which deserve of detailed study and drilling. The drilled geothermal wells in two surveyed areas in Turkey fell into the contours of the anomalous zones of the "thermal water" type, found within them. In some areas, a detailed vertical scanning of satellite data was carried out. According to the scanning data, the depths and thicknesses of the aquifers are determined, and the water temperature in them is estimated. For a more confident search for zones of accumulation of fresh (mineralized, geothermal) water, it is necessary to process remote sensing data at a scale of 1:10 000 and larger. The results of frequency-resonance processing of satellite images can be verified and refined by ground-based direct-prospecting geoelectric methods of FSPEF and VERS. The joint use of the technology of frequency-resonance processing of remote sensing data and ground-based geoelectric methods of FSPEF and VERS allows accelerating and optimizing the process of prospecting and exploration of geothermal sources. Approved mobile geophysical methods are recommended for practical use in prospecting and exploration of geothermal waters within known zones of wide development of geothermal sources.
