Abstract
The Hongshan Copper Mine in Shangri-La City,Yunnan Province,has experienced complex tectonic changes,magmatic activities,sedimentary formation and metamorphism,providing powerful conditions for the formation of minerals in the area.The mining area is located in the south section of the Yidun-Zhongdian Island arc belt to the west of the Ganzi-Litang junction zone and to the east of the Dege-Zhongdian landmass,and the main structural line is distributed in the NNW direction.The area is a carbonate platform in the late Paleozoic.During the Permian-Early Triassic,with the development of the Ganzi-Litang small ocean basin on its east side,it changed into a passive continental margin.During the end of the Middle Triassic to the beginning of the Late Triassic,with the subduction of the Ganzi-Litang small ocean basin to the west,it formed an active continental margin.The purpose of this study is to provide a new idea for future ore prospecting and exploration through the discussion and study of the metallogenic geological characteristics of the deposit in the mining area.关键词
