Clay mineralization is a generalized alteration of interlayer oxidized sandstone-type uranium deposits. The role of clay minerals in uranium mineralization has always been one of the important contents of this type of uranium deposit research. In this paper

the characteristics of clay minerals in the Saihan Formation of the ore-bearing target layer in the study area were studied and analyzed by field core observation

microscopic analysis of rock and mineral identification

and scanning electron microscopy and energy spectrum analysis. The author found that there is obvious clay mineralization in the Saihan Formation of the target layer. It is believed that the adsorption of clay minerals is one of the main factors for the formation of uranium mineralization.
