AbstractMuch of the basement to the southwest Athabasca Basin comprises rocks of the Lloyd Domain. These include the Careen Lake Group, a melange of metasedimentary rocks, parts of which are correlative with Archean Murmac Bay Group and Rutledge River Basin rocks. These rocks were intruded by ca. 1985 - 1968 Ma plutons of the Taltson magmatic zone. The Lloyd Domain was divided by weakly
deformed 1843 Ma granite and 2500 Ma granitic gneiss of the Clearwater Domain. To the east, supracrustal rocks of the 'Virgin schist group' are at the boundary between the Virgin River and Lloyd domains.

Most basement rocks to the western Athabasca Basin were subjected to multiple deformational and metamorphic events. The Virgin River shear zone was subjected to multiple displacement episodes under ductile, brittle-ductile, and brittle conditions. Brittle reactivation of the Virgin River shear zone, along the Dufferin Lake Fault, played a role in concentrating uranium at the basal unconformity of the Athabasca Basin.
