4th Biennial SGA Meeting on Mineral Deposits - Research and Exploration: Where do They Meet, Turku, Finlandiya, 11 - 13 Ağustos 1997, ss.591-594
The Eskisehir - Sivrihisar Basin composed mainly of metamorphic and ultrabasic rocks Miocene and Pliocene rocks are represented by limestones, sandstones, claystones and tuffs respectively in which the main non-saline mineral group is clay assemblage. The gypsums has been precipitated within this sequence. Field studies and geochemical data have revealed that the investigated gypsums had been formed under different conditions of deposition in the same basin. As a result of multi-periodic evaporation processes, the formation of laminated-bedded gypsums, rose shaped-bedded gypsums and scattered gypsums are postulated in the area.
