摘要
Located in Bolohuoluo palaeozoic arc belt, the Kendenggaoer Cu-Mo deposit has aroused much attention among geologists. The ore bodies, in the tabular, laminated and lenticular forms, occur in the outer contact zone between Late Carboniferous granodiorite and Upper Carboniferous carbonate rocks. Metallic minerals in the ore include mainly chalcopyrite and molybdenite, while gangue minerals are mainly diopside and andradite. Sulfide minerals, existing as euhedral or xenomorphic crystals with stockwork and dissemination structures, are distributed in the skarn rocks. Endogenic ore-forming process has obviously experienced two stages of mineralization i.e., skarn and quartz-sulfide. Therefore, the ore-forming process was related to the southward subduction of the Yilianhabierga oceanic basin in the middle of Early Carboniferous.
