桂北地区是中国重要的稀有、稀土及多金属成矿区。区内存在着五个矿床成矿系列和两个矿床成矿亚系列,其成矿作用在地质历史中具有多旋回螺旋式上升的演化规律。对于各旋回而言,从早到晚成矿物质从以幔源为主到壳源。从整个地质历史演化来看,也有幔源组成趋向减少,壳源组成逐渐增高;成矿元素组合由少到多,成矿组分趋于复杂。成矿作用在空间上显示出从古老基底向外迁移,即前寒武纪从西向东递变,显生宙以来从北向南过渡,燕山期内又自东向西演化的规律。 The northern part of Guangxi is an important rare, rare earth and polymetallic metallogenic area in China. There are five mineralization series and two mineralization sub-series in the area, and their metallogenesis has multi-cycle spiral evolution in geological history. For each cycle, from early to late ore-forming material from the mantle-dominated to the shell source. From the perspective of the entire geological history, mantle-derived composition tends to decrease and the crust source composition increases gradually. The combination of ore-forming elements is from less to more, and the metallogenic components tend to be complicated. The mineralization spatially shows the outward migration from the ancient basement, that is, the Precambrian transition from west to east, the transition from north to south since the Phanerozoic, and the east-west evolution during the Yanshanian period.
