Özet

The occurrence of celestite in the evaporitic Upper Eocene-Miocene deposits of the Sivas (Ulas) Basin is documented. This paper aims to demonstrate that a group of Tertiary sediment-hosted celestite deposits are epigenetic in origin, rather than syngenetic as has been claimed by a number of previous workers. Thin section petrography, fluid inclusion data, mineral and whole rock geochemistry and isotopic compositions (87/86Sr, 18O and 34/32S) are the main tools employed.
