- Аннотация: The Kekura gold deposit, amongst other volcanogenic Au-Ag, intrusion-related Au and porphyry Au-Mo-Cu deposits (Kupol, Dvoinoe, Klen, Peschanka, Nakhodka) of the region, is considered to be of economic importance. It is associated with the central part of the Early Cretaceous stock-shaped three-phase Kekura granitoid intrusive. Gold-bearing quartz veins and lenses occur within the intrusive and near-contact country rocks. Five types of alteration were recognized at the deposit: potassium propylitic, tourmaline–albite–sericite–quartz with molybdenum mineralization, unmineralized quartz–albite–sericite±tourmaline, quartz–sericite–dolomite with arsenopyrite and/or pyrite and argillic.
