AbstractThe Amaruq deposit map area is a glacial landscape dominated by till deposits (72% of map area) forming transverse ridges, hummocky moraine, or plains of varying thickness, occasionally streamlined. Glacial lake sediments cover about 18% of the map area and form thick to thin deposits covering the till. They occur predominantly in lowlands and below approximately 140 m a.s.l., which is the elevation of the highest raised beaches located in the western part of the map area. Some of the glacial lake sediments could have been deposited in a marine environment during high sea levels following deglaciation. Sand and gravel deposits occur in subglacial meltwater corridors forming terraces, esker ridges, and small hummocks, or in proglacial outwash plains. The effects of meltwater at the base of the glacier or by currents and waves in proglacial lake and/or marine basins have resulted in winnowing of fine particles, reworking of sediments, and surface boulder concentrations. Streamlined till landforms and striations indicate that ice flow was dominantly to the north-northwest. This predominant flow was locally succeeded by northwest and west-northwest ice flows as indicated by crosscutting striations. A late deglacial ice-flow direction converging towards a major esker tunnel is observed east of the Amaruq deposit.
Summary(Plain Language Summary, not published)
The geology map of the Amaruq gold deposit area (NTS 66-H south-east) in Nunavut identifies glacial, glaciolacustrine and glaciofluvial surficial sediments and landforms deposited by the Laurentide Ice Sheet during the last glaciation. The surficial geology is based on the interpretation of satellite images and aerial photos, and supported by fieldwork. The mapping was completed as part of an MSc thesis research project within the NSERC-Agnico Eagle Industrial Research Chair in Mineral Exploration at Université Laval. The Geological Survey of Canada is involved in co-supervising the student within the GEM-2 Glacial Synthesis Rae Project area with the objective of providing new geological knowledge and improving our understanding of the distribution, nature and glacial history of surficial materials in the Rae Geological Province. The map will support informed decision making for resource development and land use.
