Constraints On The Origin Of The Balıkesir Thermal Waters (Turkey) From Stable Isotope (\Delta^{18}O, \Deltad, \Delta^{13}C, \Delta^{34}S) And Major-Trace Element Compositions, Hali̇m Mutlu

Turkish Journal of Earth Sciences

The Balıkesir thermal waters in northwestern Turkey have discharge temperatures in the range of 31.8-98.5 ºC, near neutral pH values of 6.40 to 8.40 and TDS contents between 327 and 2578 mg/l. Samples display variable chemical compositions changing from high-temperature Na_2SO_4-NaHCO_3 waters to warmer CaHCO_3 waters. Trace element concentrations of the waters show significant variation. Comparison between the concentrations of alkaline earth metals in waters and carbonate deposits reveals mobile behavior for Mg and Ba. The ratio of strontium to calcium concentrations in solid and liquid phases was found to be almost the same. Li/Cs and B/Cl ratios of waters …
