Reservoir and hydrogeochemical characterizations of geothermal fields in Salihli, Turkey

Geothermal and hydrochemical characteristics of thermal waters in the Salihli geothermal area are described in this study. This geothermal area is geographically divided into five main groups; Kursunlu, Caferbey, Greenhouse, Ufuruk and Sart geothermal fields. In the study area, the outlet temperatures of the thermal waters are between 30 and 90 degrees C. their discharges are between 2 and 80 l/s in springs and the depths of wells vary between 200 and 1189 m. Hydrochemical analysis results suggest four different water types of Na-HCO3, Ca-Mg-HCO3, Ca-Na-HCO3 and Ca-Mg-SO4 in Kursunlu, Caferbey-Greenhouse, Sart, and Ufuruk, respectively. Cold waters are mainly dominated by the HCO3 and SO4 anions and Na, Ca, and Mg cations.
