Abstract
The Derbugan metallogenic belt, which controls lots of molymetalic deposits, is an important Cu-Mo-Au-Pb-Zn molymetalic metallogenic belt in the China-Russia-Mongolia border area. Cu-Mo deposits, such as Wunugetushan, Badaguan, Babayi, are concentrated in Manzhouli and Chen Barag Banner. However, there is big ore-prospecting space in the area whether in number or in scale compared with Cu-Mo deposits in the Erguna-Upper Heilongjiang-Gangren metallogenic belt in adjacent Russia. On the basis of field geological work and investigation of the Badaguan deposit, the authors investigated geological characteristics of the deposit. On the basis of studying rock geochemical data (major elements, trace elements and REE), LA-ICP-MS U-Pb dating of zircon and Re-Os dating of molybdenite, the authors hold that the Badaguan Cu-Mo deposit is a porphyry Cu-Mo deposit related to orogenic belt and was formed in Late Indo-Chinese epoch(205.8±3.4Ma)and controlled by Badaguan short-axis anticlines or NE-SN faults. A comparison with the Wunugetushan Cu-Mo deposit shows that granite-porphyry generated in Early-Yanshanian period is probably a new type of ore-bearing rock in the Badaguan ore district. -
