ABSTRACT
Southeast Guangxi is located in the northwest margin of the Yunkai Block at the junction of the South China plate and the Cathaysia plate. The tectonic framework spreads in a north-southeast west-trending belt. It belongs to the middle research area of the Nanling metallogenic belt, which abounds with W Sn Nb Ta REE and other rare metal deposits closely related to granitoids, and has always been a key area of geologists’ research rare earth ore deposit geology research started early, in the study area in recent years, experts and scholars of rare earth ore mineral resources survey and exploration to do a lot of research work, especially on the granite mineralization and tectonic evolution study has obtained certain understanding. Research shows that the degree of rock weathering granite is higher, the greater the thickness of the weathering crust, seam quality is better, leaching rate also increased accordingly. The full weathering layer is the main ore-bearing horizon of rare earth deposits. The content of rare earth oxides is not high at the top of the full weathering layer. The ratio of heavy rare earth elements is mainly enriched in the middle and lower ore bodies of the full weathering layer. Therefore, the analysis of rare earth ore quality and characteristics in this area can provide a theoretical basis for the exploration and resource potential evaluation of rare earth ore in this area.
