The Tuz Golu basin located in Central Anatolia contains ancient (Miocene) and recent evaporite deposits. The aim of this study is to determine the origin and evolution of the ancient halite deposits in the basin, particularly whether there is a marine origin. For this purpose, the mineralogical, geochemical and isotopic properties of halite samples taken from three different drillings at the southern part of the Tuz Golu basin were determined. Halite samples in the Tuz Golu basin are characterized by Cl (60.20-61.00%), Na (39.00-39.40%) and Br (5637 ppm) contents. The Cl-, Br-, Ca, Mg2+, SO42-, and K+ values and Cl/Br (948-86428) ratios indicated that during the formation of the ancient halites in the Tuz Golu basin, the mixture of solutions had different compositions/origins and that the dissolution, recrystallization and dedolomitization mechanisms were effective.
