| Abstract | (Summary)
This publication summarizes the 2017 field work completed in the Baker Lake and Arviat areas, mainland Nunavut, as part of the GEM-2 Rae Synthesis of Glacial History and Dynamics
Activity in the interior of the Keewatin Sector of the Laurentide Ice Sheet. Field work consisted of targeted mapping of glacial flow indicators to resolve the relative ice-flow chronology at both ends of the Keewatin Ice Divide, sampling material
for age dating to help reconstruct the glacial and post-glacial histories at a regional scale, and documenting the nature and composition of the glacial sediments under the ice divide and in selected ice stream terrains. This work will provide new
geological knowledge on the chronology of ice flow events and help understand glacial transport characteristics across major glacial landscapes in the Kivalliq Region. The findings will support informed decision making for mineral resource
exploration and land use management. |
| Summary | (Plain Language Summary, not published)
This publication summarizes the 2017 field work completed in the Baker Lake and Arviat areas, mainland Nunavut, as part of the GEM-2 Rae Synthesis of
Glacial History and Dynamics Activity. The report outlines field methods and discusses preliminary results regarding the relative ice-flow chronology and the nature and composition of the glacial sediments under a major paleo-ice divide and in ice
stream terrains. 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 the Kivalliq Region. The findings will support
informed decision making for resource exploration and land use management. |
