ProgramGEM2: Geo-mapping for Energy and Minerals Mackenzie Corridor, Southern Mackenzie Surficial Mapping
Released2017 11 10
This report summarizes accomplishments of the Southern Mackenzie Surficial activity that is focused in the southern Northwest Territories. This research is being carried out in collaboration with the Northwest Territories Geological Survey, the University of Waterloo and Memorial University. The report outlines field methods and field observations regarding the regional surficial geology and reconstruction of glacial history based on detailed mapping of palaeo iceflow indicators and stratigraphy. It also discusses regional multi-media heavy mineral sampling transects that are being used to better understand long-distance glacial dispersal of indicator minerals and to potentially delimitate regions of previously unknown mineralization in the Paleozoic platform of the Western Canada Sedimentary Basin.
The overall objective of this research activity is to produce new regional geoscience data including surficial geology, geochemistry and indicator mineral maps to support natural resource exploration and responsible resource development in the southern Mackenzie corridor. Fieldwork in 2017 builds upon earlier research conducted by the Northwest Territories Geological Survey (Watson, 2011a; Watson, 2011b) and by the Geological Survey of Canada in GEM-1 (Oviatt et al., 2015; McClenaghan et al., in press). Field research in 2017 led to an improved understanding of the regional surficial geology of the study area and identified key areas for more focused mapping and sampling in subsequent field seasons.
Summary(Plain Language Summary, not published)
A summary from field activities for year one of the Southern Mackenzie Surficial Activity (2017-2020), part of the Mackenzie GEM2 Project. Includes chapters on surficial mapping and sampling of till and stream sediments for heavy mineral studies.
