[en] Based on the study of geologic characteristics of Shihongtan U-deposit, authors suggest that the deposit is a typical interlayer oxidation zone sandstone-type U-deposit, and the ore-formation is mainly controlled by ore-controlling factors such as the uranium source, the development of interlayer oxidation zone, the variation of hydrodynamic conditions etc. On the basis of summarizing these ore-controlling factors, the authors have set up a metallogenic model of the Shihongtan U-deposit.
