Investigation of Geothermal Potential of Balıkesir-Sındırgı-Düvertepe Area with Magnetotelluric Methods

Abstract

Summary It is aimed to investigate the potential of geothermal fluids to be used in the power plant. The purpose is to determine the total thickness of the sedimentary units and the basement topography, to clarify the underground structure, to identify the regions that can operate in terms of geothermal energy and the lateral discontinuities of the sedimentary units. The study was carried out in the eastern part of Sindirgi/Balikesir Province (Turkey). 60 MT and AMT measurements were made in the area and the deep geological structure was tried to be clarified. Paleozoic metamorphic rocks and the Upper Cretaceous age series which are incompatible with them were found in the study area. Upper Miocene volcanics unconformably overlie the complex sequence. These units cover alluviums unconformably, especially in stream beds. According to the results, it was found that there were many lateral discontinuities in which the throws and directions were very different from each other. When the cross-sections were examined in terms of the resistivity distributions, it was observed that low resistivities, high-very high resistivities dominated deep in the regions near the surface. The low resistivity zones between very high resistivity blocks were interpreted as a possible volcanic activity in the area.
