Abstract: Based on the studies of uranium isotope characteristics in the front of ore roll and uraniumbearing layer in the 512 deposits, the forming processes and ore prospecting markers of uranium isotopes are discussed. The results indicate that the forming process of the sandstone type uranium deposit is a multiphase rolling dynamic process from oxidation to reduction environment. The uranium ore body is mainly located in the sector Ⅲ. It is reasonable that the sector A should be named as the geochemical conflict sector according to the distributions of uranium isotope samples in the different oxidation-reduction zones and rolling features of forming process of the ore body.

Key words: isotope geochemistry, uranium isotope, hydrogeochemistry, uranium geology, uranium deposits of sandstone type
