AbstractThe Sulphur Bay map sheet is a low-relief terrain underlain by lower- to middle-Devonian dolostone and limestone. A thin (<4 m thick) Laurentide Ice Sheet-derived glacial sediment cover drapes most of the landscape, except for bedrock outcrops exposed near Great Slave Lake. Relict glacial landforms record an older northwest ice flow across the region. These are strongly overprinted by subsequent west-southwest-oriented flutings and mega-scale glacial lineations formed during deglaciation. As ice retreated, the entire map area became inundated by glacial Lake McConnell and then subsequently by the expanded postglacial Great Slave Lake. This produced a discontinuous, coarse winnowed surface lag over higher terrain and thin sheets of glaciolacustrine nearshore sands over lower-lying regions. Abundant iceberg furrows occur throughout the map area. Bogs and fens have formed over much of the landscape and display extensive thermokarst.
Summary(Plain Language Summary, not published)
Surficial geology map for western region adjacent to Great Slave Lake, which was mapped as part of the GEM2 Southern Mackenzie Surficial Activity. This map will provide detailed information on the surficial materials that were deposited in the region, which can be used for information planning, mineral exploration and future climate change scientific studies (e.g., permafrost).
