The deposit has a variety of alterations, including hydromicazation, albitization, chloritization, fluoritization, pyritization, and silicification. W, Mo, Pb can be used as indicators for searching uranium mineralization. According to the distribution pattern of REE, LREE is rich and HREE is relatively inadequate. Earth elements have inheritance and homology, and alteration effect has little impact on the distribution patterns of rare earth elements.
