Geology and mineral potential of the southern Rae Craton, Northwest Territories, NTS 75-G and H / E. Martel ... [et al.]. : M183-2/8194E-PDF

“The southern Rae craton in the Northwest Territories (NT) has seen little research since it was first mapped by canoe and float plane at reconnaissance scale in the 1950-60s. Under the Geological Survey of Canada’s (GSC) Geomapping for Energy and Minerals (GEM2) program, the GSC-Northwest Territories Geological Survey (NTGS) South Rae 1:250,000-scale bedrock mapping project is improving understanding of the evolution, economic potential, and role of this region in assembly of the Canadian Shield. Field work in 2016, focused in NTS 75G and the west half of 75H, covered over 17,500 km2 of previously unmapped ground. This study provides insights on six new, informally-named, geophysically, and isotopically defined domains, each with a distinct record of magmatic and tectono-metamorphic events. The domains have roughly northeast-southwest striking boundaries and are defined by crustal-scale structures that are marked by both high-strain ductile zones and discrete brittle faults, which appear to be the locus of multiple movements.”
