Summary:Proterozoic U deposits are preserved in sandstone formations on several Precambrian shields, and testify to the compositions and conditions required for the safe disposal of nuclear fuel wastes. The unconformity-type U deposits in the Athabasca basin of N Saskatchewan are discussed in detail. Conditions for ore formation in three deposits were similar to those expected around a waste package, in terms of P-T and salinity of the solutions. Secondary dispersion of U resulting from groundwater interactions is very limited. Only radiogenic Pb appears to have been dispersed to any extent. Two processes in the ore formation have a direct bearing on the stability of fuel waste and of buffer and backfill in the nearfield: these are redox control of groundwater by methane and quartz dissolution. The former process is still active.
