| Abstract | This report releases the field datasets and analytical results from targeted surficial geology studies and till sampling completed in 2017 and 2018 in mainland Nunavut and eastern Northwest Territories
as part of Natural Resources Canada's Geomapping for Energy and Minerals (GEM?2) Rae Synthesis of Glacial History and Dynamics Activity in the interior of the Keewatin Sector of the Laurentide Ice Sheet. Fieldwork consisted of targeted mapping of
glacial flow indicators to resolve the relative ice-flow chronology, sampling material for geochronology to help reconstruct the glacial and post-glacial histories at a regional scale, and documenting the nature and composition of the glacial
sediments in various glacial terrains. In addition to the field and analytical datasets, this report provides a detailed description of the field and analytical methods. In 2017, Quaternary geological field observations were made at 92 sites; 39 till
and 16 geochronology samples were collected in 5 areas in the Baker Lake and Arviat regions, Nunavut. In 2018, the focus shifted to the Healey Lake area in eastern Northwest Territories and central mainland Kitikmeot region, Nunavut. Quaternary
geological field observations were made at 72 sites; 44 till and 17 geochronology samples were collected. Till samples were analysed for matrix geochemistry and texture, gold grain counts, indicator mineral picking and probing, and pebble lithology
counts. |
| Summary | (Plain Language Summary, not published)
This report releases the field data sets and laboratory results from surface glacial sediment field programs completed in 2017 in the Kivalliq Region,
mainland Nunavut and 2018 in the Kitikmeot Region, Nunavut and eastern Northwest Territories. These studies provide new geological knowledge on the glacial history and the nature of surficial materials left by the retreat of the last glaciers. The
findings will support informed decision making for resource exploration and development as well as environmental assessment. The work was conducted under the Rae Glacial History and Dynamics Activity project at the Geological Survey of Canada, as
part of Natural Resources Canada's Geo-mapping for Energy and Minerals (GEM-2) Program. |
