This paper presents the main aspects of research and discus-sions on metallogenesis during collisional orogenesis after the development of plate tectonics, and accordingly divides the study history into two stages, i.e. the junior stage during 1971-1990 and the senior stage after 1990. Beginning with the negation of mineralization in the collision regime by Guild (1971), the focus of study was put on whether there occurred any mineralization during collisional orogenesis at the junior stage. At the senior stage, which is initiated by the advance of met-allogenic and petrogenic model for collisional orogenesis, scientists begin to pay their attention to the geodynamic mechanism of metallogenesis, spatial and temporal distribution of ore deposits, ore-forming fluidization, relationship展开更多

Indeed, one can say that the frontier story is one of the things that makes the Qing ＂Qing.＂ However, only in the last twenty years has the study of what is now termed the ＂borderlands＂ come into its own as a sub-field. This essay begins by describing some key concepts and terms in the study of the Qing frontier, including the Manchu wordjecen. It then raises the problem of narrative fiameworks, asking how we might best contextualize the growth of the empire, before going on to explore the implications of the discursive shift represented by the ＂New Qing History＂ and the extensive research on Qing borderlands associated therewith. A poem by the Mongol poet Na-xun Lan-bao provides the focus for a concluding discussion of a distinctive Qing frontier sensibility.展开更多
