Study area is in the zone named “Eastern Pontide Zone” which is located in the northeastern part of Turkey. On the bottom of the study area, Cretaceous aged volcanic, pyroclastic and sedimentary rocks intercalated with pyroclastic rocks take place. All these lithologic units were intersected by Upper Cretaceous-Late Eocene aged granitoids. This pluton that generates mineralization underwent low/sub-propylitic alteration. Cu-Pb-Zn mineralization occurs in the fracture zones of a granodiorite intrusion located in the southwestern part of the study area. Same mineralization has been determined in the northeastern part of this intrusive, where intrusive contact with sedimentary rocks and also, fracture zones developed in sedimentary rocks. It is determined that quartz veins with various dimensions, generally strike N40-50oW. As a result of microscope investigation, a paragenesis including galena, sphalerite, pyrite, chalcopyrite, gold, smithsonite, malachite, azurite, covellite, goethite, lepidocrocite, hematite, and limonite was determined. This paragenesis is similar to that of the porphyry-copper deposits from the region. In this study, preliminary results of detailed geological study are given for this area, which has been never studied before.
