| 摘 要： | Described in detail in this paper are the geochemical characteristics of the sandstone-type uranium deposits in northern Sichuan Province .Favorable and unfavor-able conditions for the enrichment of uranium are explored on the basis of the elemental abundances and ratios of U,Th and K determined by gamma-ray spectroscopy. Gamma-ray spectroscopic(U, Th and K) and XRF analyses(As, Ba) are helpful to distinguish U-bearing light-colored sandstones from U-barren light-colored ones and red sandstones (red claystone) from light-colored sandstones. Therefore, the favorable target area for prospecting the sandstone-type uranium deposits can be difined in northern Sichuan Province.

| Abstract: | Described in detail in this paper are the geochemical characteristics of the sandstone-type uranium deposits in northern Sichuan
Province. Favorable and unfavorable conditions for the enrichment of uranium are explored on the basis of the elemental abundances
and ratios of U, Th and K determined by gamma-ray spectroscopy. Gammaray spectroscopic (U, Th and K) and XRF analyses (As,
Ba) are helpful to distinguish U-bearing light-colored sandstones from U-barren light-colored ones and red sandstones (red
claystone) from light-colored sandstones. Therefore, the favorable target area for prospecting the sandstone-type uranium
deposits can be defined in northern Sichuan Province. |
