Abstract: Uranium is an important strategic and energy resource in China. Its resources potential was thoroughly investigated in the national mineral resources assessment project along with other 25 key minerals. During the 20062013 implementation period of the project, we documented the metallogenic pattern of uranium resources in China through geologic characterization of genetic and prediction types and temporospatial distribution of uranium deposits. Presently with the completion of uranium resources evaluation and integrating recent development in uranium exploration, we propose that the uranium deposits in China can be delineated into 29 uranium metallogenic belts and 20 uranium prospective areas. We also suggest that the deposits can be further divided into 4 classes, 9 types, 21 genetic subtypes and 50 prediction types. In this work, resource potentials of the 49 metallogenic belts and prospective area were assessed using the geological information integration method and deposit model, and each evaluation was subjected to a comprehensive statistical analysis. Our resource potential evaluation will aid China s uranium exploration and nuclear development in the future.
