Although there are several attempts to compare the age distributions on travertines with episodes of surrounding volcanism, the correlation between the precipitation record of carbonate veins and the fractural pattern around a volcanic conduit has not yet been examined. In this study, we investigate the geochronological, geochemical and isotopic characteristics of two travertine deposits (Balkaya and Sarıhıdır) surrounded by many eruption centers in the central Anatolia with ample paleoeruption records. High-resolution carbonate precipitation records revealed by U-series dating are well correlated with the compiled dataset on Acıgöl caldera and Erciyes stratovolcano eruptions with regard to fractural positioning to the volcanic centers. Syn-eruptive carbonate precipitation is thought to occur because of sudden flux of CO-rich fluid along the extensional fracture systems aligned tangential to the related volcanic conduit and, therefore, may be an alternative technique for the reconstruction of paleoeruptions. δO and δC values of the travertine sites are within the range of meteogene fluids and δO values show a similar trend to climate proxies preserved in different depositional environments throughout the world. It is likely due to that studied carbonates were precipitated under similar fluid conditions which are represented by high rate of dilatation followed by the meteoric water influx into the extensional fracture systems.
