AbstractThe Sue C uranium deposit is structurally controlled, basement-hosted uraninite associated with the unconformity between the late Paleoproterozoic Athabasca Group and older basement gneiss of the Wollaston Supergroup and Archean granite. Before the unconformity developed, pervasive schistosity axial planar to associated folds, steeply plunging extension lineations, and major reverse faults recorded subhorizontal Hudsonian compression and subvertical elongation. Mesoproterozoic reactivation of the graphitic fault zone after deposition of the Athabasca Group, caused broadly similar, but brittle kinematic events in basement rocks of highly contrasting rheology. Uraninite and minor uranophane±carn-ot ite±coffinite±galena±gold form massive nodules, shear and extension veins, and irregular replacement and dissemination zones within a variably white and red, clay-rich envelope. Sites of structural heterogeneity along overriding nonplanar surfaces inherited from Hudsonian deformation created dilatant jogs that fostered Mesoproterozoic fluid circulation and ore entrapment. The geochemical signature of the deposit is U with V+B+Pb+Mo+Be±Ni-As.
