Geothermal Exploration in the Palana Area, Kamchatka Peninsula, Using MT-AMT Soundings

Results magnetotelluric-audiomagnetotelluric (MT-AMT) soundings for geothermal exploration in the north-western part of the Kamchatka Peninsula are considered. The works aimed at the revealing of rather low depth (up to 2 km) and low and middle temperature (up to 150 o C) geothermal sources have been carried out in two stages: preliminary and detailed. At the preliminary stage on MT-AMT soundings data the prospects of several beforehand selected sites have been estimated. At the detailed stage on investigations of the most perspective site its 2D structure has been reliably determined and using the 2D inversion geoelectric sections up to the depth of 3 km have been derived. On the soundings results the supplementary investigations of an allocated deep anomaly and the subsequent checking by drilling have been recommended.
