AbstractThe Wollaston Supergroup (revised) overlies Archean gneiss along the eastern margin of the Hearne Province. Four unconformity-bounded Paleoproterozoic siliciclastic metasedimentary sequences include minor carbonate and volcanic rocks. The ca. 2075 Ma volcanic rocks and detrital zircon grains greater than 2.37 Ga restricted to the east are interpreted as rift and passive-margin deposits, respectively. Coarsening- and fining-upward foreland basin successions (detrital zircons >1.88 Ga) underlie all of the Wollaston Domain. During the 1.86 - 1.78 Ga Trans-Hudson Orogeny, four episodes of ductile deformation generated upper-amphibolite- to granulite-facies metamorphism, except for an easternmost greenschist- to lower-amphibolite zone. Zinc-lead prospects are mainly in the middle two groups, especially at George Lake. 'Redbed'-type copper occurrences e.g. Janice Lake prospect, are mainly in the youngest group. Widespread late Trans-Hudson Orogen pegmatite and granitoid intrusions contain minor uranium. Many unconformity-associated uranium deposits of the Athabasca Basin are associated with the basal graphitic metapelite unit of the foreland basin succession.
