Özet

Tuzgolu Basin located at the Central Anatolia is an inner enclosed basin and is bounded by Ankara uplift in the north, the Kirsehir massif from in the east and the Sivrihisar-Bozdag massif from the west. The Salt Lake is bordered by Tuzgolu, Aksehir and Nigde fault zones in NE-GW direction. Typical mechanical and sedimentary structures in the evaporitic sediments are observed in especially gypsum and anhydrite, partially glauberite and halite deposits. The most prominent structures observed in the investigated cores are usually sequential sedimentation or stratification, other primary structures are slump structures, sub-strata traces, mud cracks and flat conglomeratic gravel sediments. Stratification in the evaporites showed changes in the mineralogical and textural properties from the bed to the bed. There are also settlement/load structures, ripple cross lamination and cross stratification were determined. As a result of sedimentation, sedimentation-grade bedding and intercalation of clay or carbonate mud and salted mineral mud have been observed. The lacustrine sediments in the inner zones of the basin consist of Ca-Na-sulphate, Mg-sulphate sediments, claystone, carbonate alternation and partly laminated. Repeating the evaporitic sediments in mm and cm thickness provides a seasonal sedimentation view.
