of these deposits is related to fluids derived from diagenetic processes in sandstone of the El Sherana Group. Mineralization formed when a 250 o C, low latitude, oxidizing, U-bearing basinal brine from diagenetic aquifers in the Coronation sandstone descended downward into the unconformity along fracture systems created by brittle reactivation of the El Sherana-Palette fault system. Uranium deposits associated with successor basins in the Beaverlodge and South Alligator River area are older than those in the U-rich Athabasca and Kombolgie basins. Rocks that host these deposits have been folded, and then exhumed during subsequent tectonic events. These older U deposits can be considered as a potential source for detrital uraninite that fed sediments of the Athabasca and Kombolgie basins and therefore contributed to the inventory of uranium that formed unconformity-related U mineralization in the younger basins. Therefore, the occurrence of older U mineralization associated with successor basins can be considered as positive criterion for exploration of unconformityrelated U mineralization in younger Paleoproterozoic basins. iv
