Epigenetic alteration of sedimentary rocks was spatially and temporally related to deposition of uranium-vanadium ores. Mineralogic and chemical characteristics and distribution of altered rocks suggest that uranium- and vanadium-bearing pore waters that were expelled from compacted Upper Cretaceous Mancos Shale in early Tertiary time accounted for the alteration of sedimentary rocks and formation of the ores in the Upper Jurassic Morrison Formation.
