贵东岩体是我国最大的产铀花岗岩岩体之一,位于古老地块赣南粤北加里东褶皱带边缘,呈东西向展布,出露面积约1000km2。区内存在新元古代一早古生代的富铀层,如加里东构造层(Z-S)铀含量为3.3×10-6～4.6×10-6,局部达36×10-6,它们为该区铀成矿提供了丰富的铀源,因此该区壳内重熔 Guidong rock mass is one of the largest uranium granite rocks in China. It is located on the edge of the Caledonian fold belt in the southern part of southern Jiangxi Province, southern Jiangxi Province. It is distributed east-west with an area of ​​about 1000 km2. In the area, the Neoproterozoic Eocene Paleozoic enriched uranium exists. For example, the uranium content of the Caledonian structural layer (ZS) is 3.3 × 10-6 ~ 4.6 × 10-6, and the local area is 36 × 10-6. The mine provides a rich source of uranium, so the zone remelts inside
