Sažetak
The Güney waterfall area is a perched springline tufa site developed on the southeast slope of the Büyük Menders River near Güney town, in the Denizli province, Western Turkey. The site is away 12 km from the town and 72 km from the city center of Denizli. The spring waters emerge from the boundary between Palaeozoic marble and micaschist and precipitated tufa deposits downslope at the altitudes ranging from 220 to 400 metres. The tufa deposits cover an area of about 20 hectars. Flat upper surfaces of the deposits are indicative of mature stage. The waters are of the Ca-HCO3 type and supersaturated with respect to CaCO3. The stable isotope values of the spring waters are -49, 94 for δ2H and -7.15 for δ18O. The δ13C and δ18O values of active and passive tufa samples are in the range from -9.13 to -6.0‰, and from -8.44 to -7.40 ‰, respectively. These isotopic values are typical for fresh water tufa. The passive tufas give the 14C age in the range from 2000 to 5800 yr BP. According to the 14C age data, passive tufas are not older than Holocene. The stable isotope composition is similar south European examples.
