AbstractThis report presents results from field work on southern Melville Peninsula during 2010, part of Geo-Mapping for Energy & Minerals (GEM) Multiple-metals - Melville Peninsula Geoscience Project. Along the coast of the peninsula, ice flow was warm-based and seaward during late-glacial and deglacial time. Across the Rae Isthmus, ice flow was northward and reversed to the south along the southern coast during deglacial time. Ice-flow history and glacial geomorphology show that on the central part of Southern Melville, some cold-based regions persisted during the last glaciation, and elsewhere the glacial regime was permanently or intermittently warm-based during that period. Complementing extensive pre-existing research, a focused drift sampling survey was conducted to assist mineral exploration in regions underlain by prospective bedrock but mantled by glacial deposits of varying thickness. The silt-sized till matrix geochemistry, the heavy mineral concentrates from till mineralogy and mineralized erratic boulders were analyzed for base metals, gold, uranium, gemstone and diamond potential.
Summary(Plain Language Summary, not published)
The surficial geology of southern Melville Peninsula, Nunavut, exhibits glacially-transported minerals and chemical elements in till that helps mineral exploration. This report helps understand the geomorphology and the history of ice flow, both necessary to mineral resource and environmental studies.
