The GEM-2 Rae Synthesis of Glacial History and Dynamics Activity centers on the interior region of the Keewatin Sector of the Laurentide Ice Sheet (LIS) and is divided into sectors, 1 (east) and 2 (west) for research management purposes. This publication summarizes the 2018 fieldwork completed in Sector 2 centered on the Aylmer-Healey lakes area of eastern Northwest Territories and mainland Kitikmeot region of Nunavut, as well as data compilation progress in Sector 1 over the Kivalliq and Kitikmeot regions.
The 2018 summer's fieldwork focused on targeted mapping of glacial flow indicators to provide insight into the ice-flow chronology west of the Keewatin Ice Divide (KID), documenting the nature and composition of the glacial sediments in various glacial terrains, and sampling material for age dating to help reconstruct the regional glacial and deglacial histories. This work will provide new geological knowledge of the glacial landscapes to address specific scientific questions with respect to the paleo-glacial dynamics of the Keewatin Sector of the LIS. This work is relevant to the mineral exploration industry, communities and government by supporting informed decision making for resource exploration and land use management.
Summary(Plain Language Summary, not published)
This Open File report summarizes the 2018 field work activities completed in the Healey Lake NWT and adjacent Kitikmeot,NU area for the GEM2 Rae Glacial Synthesis Activity. The report outlines the research methods and provides and discusses preliminary results regarding the relative ice-flow chronology and the nature and composition of the glacial sediments of various glacial landscapes.The work was undertaken to provide new geological knowledge on the history of ice flow events and help understand glacial transport characteristics across major glacial landscapes in this region. The findings will support informed decision making for resource exploration and land use management.
