ProgramSouth Rae Province Bedrock/Surficial geology, GEM2: Geo-mapping for Energy and Minerals
Released2015 11 26
The Geo-mapping for Energy and Minerals (GEM) program is laying the foundation for sustainable economic development in the North. The Program provides modern public geoscience that will set the stage for long-term decision making related to investment in responsible resource development. Geoscience knowledge produced by GEM supports evidence-based exploration for new energy and mineral resources and enables northern communities to make informed decisions about their land, economy and society. Building upon the success of its first five-years, GEM has been renewed until 2020 to continue producing new, publically available, regional-scale geoscience knowledge in Canada's North.
During the summer 2015, GEM program has successfully carried out 17 research activities that include geological, geochemical and geophysical surveying. These activities have been undertaken in collaboration with provincial and territorial governments, northerners and their institutions, academia and the private sector. GEM will continue to work with these key collaborators as the program advances.
Summary(Plain Language Summary, not published)
The Geological Survey of Canada, as part of its Geo-Mapping for Energy and Minerals Program, in partnership with the Northwest Territories Geoscience Office will conduct a three-year geology research project in southeasternmost Northwest Territories. The aim of the project is to fill in major gaps in bedrock and Quaternary geoscience understanding in Canada's north where geological data do not currently exist. This report summaries results of the 2015 field season, which was focused in the 75A and B map sheets. Highlights include: 1) the identification of new geological domains in the area, major new fault zones and seven new mineral occurrences, 2) identification of four phases of regional ice flow during glaciation and discovery of a extensive glacial lake system in the area. As part of the study over 300 bedrock and 800 surficial (till, lake sediment and waters) samples were collected for analysis.
