Fluid inclusion studies on copper - gold mineralization in Hacımeter - Tekman (Erzurum)

In the Erzurum-Tekman region, the oldest unit in the study area is represented by the Karataştepe Metamorphics, which are overlain by units belonging to the Şahvelet Ophiolites. Copper mineralizations in the Tekman area are generally observed as lenses within metavolcanic rocks, which are commonly associated with the region's widespread ophiolitic rocks. The most common ore minerals identified are pyrite, magnetite, and chalcopyrite, while quartz is the predominant gangue mineral. Fluid inclusion studies have determined that the primary inclusions in quartz have temperatures ranging from 150 to 183°C and salinities between 0.00 and 4.182 wt% NaCl. The data obtained regarding the mineralization indicate that the ErzurumTekman mineralization is a typical example of Cyprus-type deposits. KEYWORDS: Erzurum, Tekman, Copper, Gold, Fluid Inclusion
