Ores in the Salt Wash belong mainly to the tabular subtype of sandstone hosted uranium-vanadium deposits, although roll-front processes overprint and redistribute metals in some areas (Burrows, 2010).Vanadium, and its common associate uranium, are most soluble in their oxidized V(V) and U(VI) forms and precipitate mainly by reduction.
