Abstract: The rocks of Gümüşki area consist of units ranging in age from Jurassic to Tertiary. Jurassic aged Pontid Lower Basic Complex, which is composed ofspiliiic basalt, andesitic lavas and pyroclastics, is overlain by Malm - Lower Cretaceous aged Berdiga formation. Upper Cretaceous Ore - bearing dacites are the units with ore mineralization. In the region Dikkaya dacite and Kıranobaunit are also Upper Cretaceous in age and do not contain mineralization. Tertiary aged Zigana granitoid caused a contact metamorphism by cutting these units.In the area vein and massive sulphide type mineralizations are controlled by fracture system related to Valles - type caldera development. In the region the vein type ore deposits are important for Zn. Pb andAu mineralizations. Syngenetic par agenesis in theveins of epimesothermal character is given as sphalerite, galena, pyrite, chalcopyrite, fahlerz, freibergite, native gold and electrum.It is observed that gold, silver and cadmium increase with increasing antimony, leadandzinc, respectively.
