Recharge Conditions of the Low Temperature Paratunsky Geothermal Reservoir, Kamchatka, Russia

The Paratunsky geothermal field is a classic example of a low temperature hydrothermal reservoir of meteoric origin. Hydrogeochemical zoning reflects a different intensity of water exchange in the Western and Eastern sites of the field. The hydrogeochemical history of operations 1966-2015 shows the involvement of chloride waters across the field's Eastern boundary. Water recharge to the Paratunsky geothermal field is provided mostly by meteoric waters from elevations above +1150 masl. The most likely area of water recharge to the Paratunsky geothermal fields is the Vilyuchinsky volcano (elevation 2173 m abs.).
