Post-Taltson sedimentary and intrusive history of the southern Rae Province along the northern margin of the Athabasca Basin, Western Canadian Shield

The formation of widespread trans-tensional basins, together with extensive dyke emplacement, implies a period of intense brittle to brittle-ductile deformation throughout the western Churchill Province at about 1.83-1.82 Ga. This deformation is attributed to a broadly east-west stress regime imposed by accretion of the Nahanni-Fort Simpson Terrane to the west, combined with terminal collision in the Trans-Hudson Orogen to the east.
