“…Hottah Terrane; Hildebrand et al 2010a), which facilitated a switch from east-dipping to westdipping subduction (Calderian Orgeny; Hildebrand et al 2010a). Arc accretion in the Great Bear Magmatic Zone (Cook et al 1999;Hildebrand et al 2010b) and Fort Simpson Terrane (Villeneuve et al 1991;Pilkington & Saltus 2009;Crawford et al 2010) during east-dipping subduction (Cook et al 2005) occurred between c. 1880 and 1840 Ma (Cook 2011). The accretion of these terranes and deformation along the Archaean margin of the Slave Craton is intimately linked to dextral transcurrent movements on the continent-scale Great Slave Shear Zone (Hoffman 1987).…”

“…Hottah accretion was immediately followed by eastward subduction, producing the epi-orogenic Great Bear magmatic arc, active between 1.88 and 1.84 Ga (Hildebrand et al 2010;Cook 2011Cook , 2013Hayward and Oneschuk 2011). Terminal collision in Wopmay orogen involved accretion of the buried Nahanni -Fort Simpson terrane ~1.84 Ga, also as a consequence of east-dipping subduction as inferred from seismic profiling (Cook 2011(Cook , 2013.…”

“…Based on the geology as it is known today, the Fort Smith area (Wilson 1941a) includes granitoid rocks of the west-facing Taltson magmatic arc (geon 19) and, to the east, gneisses and high-grade metamorphic rocks belonging to the Arrowsmith orogen (geon 23) of the Rae craton (Thériault 1992;Berman et al 2013). The Ingray Lake area (Wilson and Lord 1942) includes a transect of the Wopmay orogen (geon 18) directly south of the Redrock culmination and, to the east, a major Neoarchean sedimentary-volcanic belt (Yellowknife Group) within the Slave craton (Hoffman and Hall 1993;Cook 2011;Jackson et al 2013).…”
