摘要
云南省香格里拉市红山铜矿经历了复杂的构造变动和岩浆活动、沉积建造和变质作用,为区内矿产的形成提供了有力条件。矿区处于甘孜—理塘结合带以西、德格—中甸陆块以东的义敦—中甸岛弧带南段,主体构造线呈北北西向展布。区域上晚古生代为碳酸盐岩台地,二叠纪—早三叠世随着其东侧甘孜—理塘小洋盆的发育转变为被动大陆边缘,中三叠世末—晚三叠世初随着甘孜—理塘小洋盆向西俯冲形成主动大陆边缘。旨在通过对该矿区矿床成矿地质特征行探讨研究,为今后的找矿、探矿提供新的思路。
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.
