We present noble gas isotope and gas composition data from eight production wells of the Kizildere geothermal field and from six gas discharging pools from the adjacent Tekke Hamam geothermal field, situated in the eastern segment of the Buyuk Menderes Graben system in western Anatolia (Turkey). Gas from both locations is composed mainly of CO2 with minor contributions of N-2, H2S, CH4, O-2, Ar, H-2, C2+ and He, with higher contents of H2S. He and C2+ in Tekke Hamam samples.
