Abstract

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.
