High Enthalpy Geothemal Potential Possibility in SW of Büyük Menderes Graben, Turkey

Abstract

The objective of this study is partially to assess the geothermal energy potential of Ortaklar-Gümüşköy-Söke extension of Buyuk Menderes Graben, by means of geochemical surveys. The study area roughly located at the SW extension of Buyuk Menders Graben. A model for the geothermal area, derived from geochemical and isotopic data, indicates a promising geothermal potential, at least in northern part, near Gümüşköy region. From geochemical point of view, the Ortaklar-Söke geothermal field is not strictly connected to Gemencik-Hıdırbey geothermal field tectonics. Physical, chemical and isotopic investigation of hot and cold ground waters make it possible to construct the thermal water evolution from infiltration to discharge, including water-rock-gas interaction, heating and shallow water mixing. By means of the applied geochemical techniques 75-170 degree C geothermal fluid was found in the study area.
