ProgramSouth Rae Province Bedrock/Surficial geology, GEM2: Geo-mapping for Energy and Minerals
Released2018 02 21
Summary(Plain Language Summary, not published)
South Rae province in the Northwest Territories has seen little research since it was first mapped by canoe and float plane at reconnaissance scale in the 1950-1960s. Under the GEM2 program, the collaborative GSC-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 was focused in map sheet NTS 75G and the western half of 75H and covered over 17,500 km2 of previously unmapped ground. This mapping provides insights on six new, informally-named, geophysically and isotopically defined domains each with a distinct record of magmatic and tectono-metamorphic events and metallogenic potential. 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.
