In this paper, the authors investigated rare earth minerals in the weathering granite crust of the Gangxia REE deposit in Anyuan, southern Jiangxi, with the purpose of revealing the morphology and distribution of secondary weathering-related rare earth minerals. Samples collected from different layers of the studied weathering crust were purified by separation. The main clay minerals closely related to rare earth minerals are kaolinite and halloysite. FE-SEM and TEM results indicate that, in this profile, nano-sized REE-bearing minerals occur in two modes: some micro-grains are attached on the surface of some minerals, whereas others exist as aggregates of rare earth minerals(possibly cerianite). The results help to understand the process of secondary enrichment of rare earth elements during weathering of granites in South China.
