URANIUM ORE DEPOSITS IN NORTHEASTERN NIGERIA: GEOLOGY AND PROSPECT

Uranium potential in northeastern Nigeria occurs in sandstone-hosted and vein-type mineralization. Sandstone-hosted deposits occurs in sedimentary/volcanosedimentary sequences in structurally controlled Bima sandstone (B₂, B₃) at Zona and Dali, while the vein-type mineralization occurs in the deformed migmatites and granitoids at Gubrunde, Kanawa, Ghumchi, Mika and Monkin-Maza deposits. Sandstone deposits have been drilled by Nigeria uranium mining company (NUMCO) and seems to be elusive, which leads to its failure to search for economic deposits, the possible economic deposits is the vein-type.
