摘要
本文以武夷山成矿带地质构造演化和岩浆活动为主线,将武夷成矿带分为元古代、古生代和中生代三大成矿期及相应的赋矿地层系统,划分为七个成矿系列:即晋宁裂谷期海底火山喷流型块状硫化物矿床成矿系列;加里东块体拼合期金铜钼矿床成矿系列;海西裂陷扩张期铁铜锰矿床成矿系列;早燕山裂陷扩张期铜银铅锌锑矿床成矿系列;早燕山地壳重熔期钨锡铋钼铌钽和稀土矿床成矿系列;晚燕山底侵伸展期铁铜铅锌矿床成矿系列;晚燕山大陆扩张裂解期铜金银铀矿床成矿系列。根据地质构造演化、岩浆活动,成矿系列和代表性矿床等特征,提出了武夷山成矿带构造-岩浆-成矿作用与演化的事件格架。
To reason about the geotectonic evolution and magmatic activity in Wuyishan metallogenic belt, Wuyishan metallogenic belt can be divided into Proterozoic,Paleozoic and Mesozoic metallogenic epochs and corresponding ore-bearing stratigraphic systems, as well as seven metallogenic series： marine volcano exhalative metallogenic series of massive sulfide deposit in Jinning rift period; metallogenic series of Au-Cu-Mo deposits in Caledonian block amalgamation period; metallogenic series of Fe-Cu-Mn de posits in Hercynian rift extension period; metallogenic series of Cu-Ag-Pb-Zn-Sb deposit in early Yanshanian rift expansion period; metallogenic series of W-Sn-Bi-Mo-Nb-Ta-REE deposits in early Yanshanian crust remelting period; metallogenic series of Fe-Cu-Pb-Zn deposits in late Yanshanian underplating extension period; metallogenic series of Cu-Au-Ag-U deposits in late Yanshanian continental spreading break-up period. According to the characteristics of geotectonic evolution, magmatic activity, metallogenic series and typical deposits, the frame of the tectonomagmatic mineralization and evolution in Wuyishan metallogenic belt is proposed.
