PRELIMINARY DISCUSSI0N ON THE CLASSIFICATION OF URANIUM DEPOSITS IN CHINA

The classification of uranium deposits is a comprehensive and complicated problem which is of great importance for the guide in prospecting and exploration. This paper reviews the merits and shortcomings of various classifications sumitted by uranium geologists in the world based on origin, geotectonics and host rocks. Considering the reasonable parts in previous classifications and characteristics of uranium metallogenesis in China, the authors suggest a new classification of uranium deposits of China mainly according to host rocks, and also depo- sits' structure and morphology of ore bodies. This classification is composed of 7 groups divided into 25 subgroups. Finally, an indication and explanation are presented in order to draw attention of the Chinese uranium geologists and make further discussion among them.
