Uranium is anomalous in groundwaters proximal to mineralization but is likely unassociated with the hypogene source. Uranium is known to be mobile in groundwater systems and precipitate in paleo-topographic lows of cover sequences (Boyle, 1984; Hambleton-Jones, 1984; Hussein et al., 1992; Johnson et al., 1987; Zielinski et al., 1987).Web
