G-16 It is a geothermal origin warm spring water cropping out on the Çaydamar Stream flowing through the Çaydamar valley. Geothermal spring waters are formed by the infiltration of meteoric waters such as snow and rain water on the surface to the underground and heating up with the effect of the underground geothermal gradient and resurfacing through the fault channel. The temperature of the hot water coming to the surface through fault systems that cut the Lower Carboniferous aged limestones in the locality decreases with the effect of the cold water sources in the vicinity. Since limestones are also a good cold water aquifer, the surrounding cold water sources naturally mix with the hot water source, causing the temperature of the existing hot water to decrease. Hot water, which comes from the depths of the ground and has a temperature of 27°C on the surface, is chemically sulfurous and calcium bicarbonate.
