This geothermal area is geographically divided into five main groups; Kurs ßunlu, Caferbey, Greenhouse, Üfürük and Sart geothermal fields. In the study area, the outlet temperatures of the thermal waters are between 30 and 90°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-HCO 3 , Ca-Mg-HCO 3 , Ca-Na-HCO 3 and Ca-Mg-SO 4 in Kurs ßunlu, Caferbey-Greenhouse, Sart, and Üfürük, respectively. Cold waters are mainly dominated by the HCO 3 and SO 4 anions and Na, Ca, and Mg cations.

İnceleme alanı içerisinde temeli oluşturan Tersiyer yaşlı Yuntdağ volkaniti-I jeotermal sistemlerin akiferidir. Bu birimi örten Demirtaş piroklastikleri geçirimsiz olduklarından örtü kayaç özelliğindedir. İnceleme alanı içerisinde soğuk yeraltı suları açısından akifer olma özelliği taşıyan önemli bir birim de alüvyondur.

Thermal waters are hosted by Menderes massif metamorphic rocks, which are made of gneisses, schists and marbles. Impermeable clayey units of the neogene sediments are cap rocks of the geothermal system. Presence of geothermal waters is closely related to normal fault systems and graben tectonic. Meteoric waters recharging the reservoir rocks are heated at depth with geothermal gradient. The AK-2 and KG-1 wells have the third and fourth highest temperatures of Turkey, respectively. Reservoir temperatures of the geothermal system are estimated to vary between 125 and 225°C by mineral equilibria geothermometer, vary between 160 and 240°C by Giggenbach triangular diagram and vary between 150 and 250°C by silica enthalpy-mixture model. Cold water contributions to thermal waters vary from 75 to 95%. Na-HCO 3 water type is dominant for thermal water. Major reaction of the thermal water to change facies is softening reaction. The temperatures obtained from silica enthalpy model, mineral equalibria geothermometers, Na/K, Na/Li geothermometers are more useful than others in the study area. Scaling tendencies of the thermal water are examined. The major environmental problem in the groundwater is high boron concentration which is harmful for agricultural irrigation.

Thermal and mineral waters, issuing from natural springs and drilling wells, were evaluated from hydrogeological and hydrogeochemical points of view. Origins, mineral saturations, aquifer temperatures, aquifer fluid compositions and aqueous species distributions have been studied by using analytical data of waters. Miocene Yuntdağ volcanic-I, which consists of andesitic volcanics, is the oldest unit and occurs as aquifer for aforementioned all the geothermal systems. Overlying Pliocene Demirtaş pyroclastics, which are ignimbrite and felsic pyroclastics, cap the systems because of their low permeability values. Quaternary alluvium is the aquifer for cold ground waters.
