Geochemical characteristics of REE in a uranium deposit

Analysis and research are based on REE geochemical parameters and chondrite-normalized REE distribution curve of each geochemical and tectonic belt in a uranium deposit. The results show that magmatite have the same characteristics of REE with ore in this deposit, and the uranium mainly come from the mining area granite which is rich in uranium. Variation of REE features show that metallogenic environment change from relatively reducing environment to relatively oxidizing conditions and the temperature of mineralization is decreased gradually in the mineralization.
