AbstractThe Adelaide Lake area is of moderate relief characterized by streamlined till blankets in the lowlands, and till veneers with extensive bedrock outcrops at higher elevations. The region was differentially eroded by the Laurentide Ice Sheet throughout Wisconsin time, multiple phases of ice flow imparted erosional ice-flow landforms and paleo-flow indicators on the landscape. However, the dominant eastward-trending, glacially streamlined landforms were formed by ice streaming during deglaciation. Terrain at higher elevations has been scoured by meltwaters from late-phase ablation of the ice sheet during deglaciation, which fed into an esker network splaying across the map area that trends from southeast to east-southeast. Lowland fens, glaciolacustrine strandlines, and littoral sediments that surround isolated streamlined till units in the southeastern portion of the map mark the former northeastern extent of inundation of a large, shallow glacial lake (glacial Lake Low).
Summary(Plain Language Summary, not published)
Surficial geology map from the GEM2 Core Zone Surficial Activity straddling the border between Quebec and Newfoundland and Labrador. This map provides the regional framework surficial geology in a region of Canada previously unmapped.
