华南地区位于中生代欧亚大陆板块构造岩浆活动带的华南陆块中部,横跨扬子板块和华夏板块,是我国有色金属、稀有金属、稀土金属和贵金属等资源的重要矿产区(蔡锦辉和韦昌山等.2009)。由于板块俯冲造成强烈的地壳构造运动,华南地区形成了非常丰富的花岗岩(张岳桥等,2009;南京大学地质学系,1981)。三稀金属 South China is located in the central part of South China Block of the Mesozoic Eurasia tectonic magmatism belt and traverses the Yangtze Plate and the Huaxia Plate. It is an important mineral area of ​​nonferrous metals, rare metals, rare earth metals and precious metals in China (Cai Jinhui and Wei Changshan et al. .2009). Due to the strong crustal tectonic movement due to the plate subduction, abundant granites are formed in southern China (Zhang et al., 2009; Department of Geology, Nanjing University, 1981).
