| Abstract: | Expounding geochemical characteristics of sandstone-type uranium deposits in northern Sichuan,this paper demonstrates the favourable and unfavourable conditions for enrichment of uranium on the basis of element abundances and ratios of U,Th and K measured by the gamma-ray spectroscopy surveying. The differences between uranium-bearing and non-uranium sandstones and between red sandstone (claystone) and greenish sandstone can be determined by the gamma-ray spectroscopy (measuring U,Th and K) and XRF analysis (measuring As and Ba). Therefore, the prospecting of the sandstone-type uranium deposits in northern Sichuan can be concentrated in a certain ranse. |
