Abstract :
Study area is located in Eastern Azerbaijan province, 27 km far from east Bostanabad, and the north of Qarehchaman geological map. According to field tracking and surveys, host rock of mineralization is a Subvolcanic rocks of Oligocene period. Based on microscopic studies, the most important of supergene part, containing primary oxide minerals (Magnetite), secondary oxide minerals (Malachite, Hematite and Goethite) and also sulphide minerals such as Chalcocite, Covellite, Pyrite and insignificance Chalcopyrite. Among the most important alterations, argillic, silicification, carbonization and propylithic can be noted. Geochemical studies shows that host rock of mineralization with Monzosyenitic composition, placed in high chalc-alkaline to shoshonitic and metaluminous range. Formation environment of host rock of mineralization is a volcanic arc of subduction zone that confirmed by normalized rare earth elements diagrams.
