Precambrian geology, Leith Peninsula–Rivière Grandin area, Northwest Territories / author, R.S. Hildebrand.: M183-1/153-2013E-PDF

"The Leith Peninsula map area lies along the western margin of the Canadian Shield and is dominated by Paleoproterozoic rocks of Wopmay Orogen. The oldest rocks, termed Hottah terrane, constitute the metamorphic basement to volcanic, plutonic, and sedimentary rocks of the 1.875-1.843 Ga Great Bear magmatic zone. Hottah terrane is interpreted as a precollisional arc that collided with Slave Craton and its west-facing passive margin during the 1.88 Ga Calderian Orogeny. Rocks of the Great Bear magmatic zone are interpreted as a postcollisional arc, were folded about northwest to northerly trending axes, and are cut by abundant transcurrent faults. A swarm of northwesterly trending diabase dykes, dated at 1740 Ma, cut the faults"--Abstract.
