Özet

Barite and sulfide bearing barite mineralization are located at eleven different sites in a 100km long and 15km width zone of NW-SE trending between Antalya and Mersin regions of the Taurus Belt. Whereas some locations are rich only in barite, others are rich in barite-galena and sulfide minerals. The mineralization occurred in the epimetamorphic and carbonate rocks of Cambrian-Devonian, Permian, and Triassic in the Antalya and Alanya Naps of Central Taurides. The ores formed mostly as vein, though stratiform, lens, dissemination, stockwork, and karst filling may occur. Mineral assemblage includes barite, galena, pyrite, chalcopyrite, tetraedrite, marcasite, sphalerite, digenite, bornite, and supergene and gangue minerals. Mineral determinations show two barite stages. First stage barite has tabular form, cleavage, and locally massive. Second stage barite has euhedral-subhedral and locally individual, locally combination with solution to each other. Based on the relations with host rocks of the mineralization, deposition forms, paragenesis, textures and the forming succession of minerals, the mineralization is epigenetic and of hydrothermal origin. It occurred at medium-low temperature of probably 100-200 degrees C, and formed from mixing fluids of different waters with interacted with host rocks.
