The REE-bearing rock series of the Xuanwei Formation is primarily distributed from the Zhaotong-Xuanwei-Qujing in eastern Yunnan to the west of the Hezhang-Liupanshui region in western Guizhou. The thickness of rare earth ore-bearing rock series varies from large to small due to the transition from continental to marine faces, with paleogeomorphology and volcanic basalt tuff interspersed. Additionally, the grade of rare earth decreases from high to low with decreasing thickness.
