Preliminary Datas of Carbonate-rock hosted barite Mineralization in Dadağlı (Kahramanmaraş) area, Turkey

Abstract

There are units existing to the Amanos Group in the vicinity of Dadaglı (Kahramanmaraş). Paleozoic aged rocks and Mesozoic aged carbonates are observed on them. There is vein type barite mineralization in the fracture lines of the Upper Triassic-Lower Jurassic Küreci dolomitic limestones in the north of Dadağlı. Paragenesis consists of galena, sphalerite, pyrite, smitzonite, calcite and quartz, individually. The mineralization is roughly 1 m thick and 200 meters long. The BaO value amounts to a peak of 65.07% in the specimens gathered from the ore zone. Although the ore zone is poor in SrO, it is rather rich in SiO2. It is concluded that the mineralization, which is particularly close to the left-lateral strike-slip East Anatolian Fault (EAF), forms in fractures and cracks set up as a result of deformations.
