 abstract={Orenagil barites are observed as space fillings, veins, and lenses incompatible with the host rock within the Devonian-aged Meydan formation belonging to the Bitlis metamorphics observed in the Bitlis suture zone in the north of Sason (Batman, Türkiye). Bitlis metamorphites are an important unit that hosts many mineral deposits. Since the study area is very close to the Bitlis suture zone, the effect of tectonism is intensely observed in the field. The mineral assemblage consists of barite, pyrite, chalcopyrite, hematite, goethite, magnetite, bornite, chalcocite, covellite, malachite, azurite, and limonite. The BaSO4 content of barite samples ranges from 25 to 61 wt% and contains high SrO (2.04 wt%). Fluid inclusions observed in barite samples are predominantly of the fluid-rich two-phase (Liquid+Vapour) type. Homogenization temperatures of fluid inclusions in barites are observed in a wide range (169 to 382.1°C), and salinity values are collected in two different groups (0.27–6.9 wt% NaCl and 12.7–20.45 wt% NaCl). Eu/Eu* values (11.20–121.36) of barites indicate exhalative hydrothermal fluids, whereas Ce/La > 1 (10.03–54.76) indicates a terrestrial origin for barites. In spite of the average REE pattern of barite and their similar host rocks, barite differs from host rocks in terms of their negative Ce peak and strong positive Eu peak. The trends of the REE values of the samples and the values of the barites in the CeN/SmN–CeN/YbN diagram indicate that the barites are formed from multiple sources, including seawater and meteoric water.},
