The Ulutaş skarn deposit lies within the Eastern Pontides magmatic belt. The study area consists of a Paleozoic metamorphic basement cross-cut and overlain by volcanic, volcano-sedimentary, and plutonic lithologies of the Jurassic to Eocene age. The metasedimentary package mainly comprises schist, gneiss, amphibolite, and lenses of marble. A large batholithic complex of granitic and granodioritic coarse-grained intrusive rocks have been emplaced into the metasedimentary basement during the Cretaceous. Various mineralized zones, including a Cu-Mo porphyry and Cu-Zn skarn systems were developed within or peripheral to these granitoids. The Skarn zone that this study focuses on was formed as a result of the replacement of calcareous country rocks by prograde calc-silicate assemblage comprising garnet, pyroxene, and wollastonite. Retrograde epidote-chlorite-sericite-tremolite/actinolite-carbonate-hematite developed as an overprint to the calc-silicate assemblage. The main Cu-Zn mineralization at Ulutaş Skarn zone is associated with this later retrograde stage characterized by abundant chalcopyrite and sphalerite accompanied by pyrite.
