Structurally-controlled metallogenic processes in the central and southern Great Xingan mountains

摘要：

The central and southern Great Xingan mountains are one of the important metallogenic provinces in east China and located in the southeast of Inner Mongolia. On the basis of regional strata,magmatic activities, and geophysical information,this paper discusses the characteristics of regional structure and its constraints on ore deposits in the central and southern Great Xingan mountains. The zoned deformation, the metamorphism and intensive magmatism around the axis of the Great Xingan mountains are the major representation of mantle branch activity. The ore deposits are hosted in ductile- brittle shearing zones and detachment zones of mantle branch structures.
