Afsin, M2019-08-012019-08-0120000943-0105https://hdl.handle.net/11480/5771The main aquifer of the Helvadere springs that emerges on the strike-slip of the Hasandagi fault set alongside the Tuzgolu (salt lake) fault zone, and trends in a NW-SE direction of Aksaray city, in the western part of Central Anatolia, is the exposed rocks of Hasandagi which are volcanics that have distinct hydrogeological properties. The meteoric origin of the spring waters is deduced from hydrochemical and environmental isotope (O-18, H-2, H-3) studies. The springs have high discharge (Q>100 1/s) and low ion concentrations because of fast circulation along the groundwater flow path in the aquifer. Furthermore, because it has hydrochemical facies, it conforms Ca-Na-Mg-HCO3 hydrochemical facies, it conforms to high standards of drinking and irrigation water.eninfo:eu-repo/semantics/closedAccessdrinking springfast circulationHelvaderehydrochemical faciesisotopevolcanic aquiferArticle3910119011962-s2.0-0034282028N/AWOS:000089617800014Q3
