| Abstract | The Lac aux Goélands area is of moderate relief characterized by till blankets in the lowlands and till veneers with large expanses of bedrock outcrops in the western and eastern margins. Bedrock was
variably eroded by the Laurentide Ice Sheet, east of the Ancestral Labrador ice divide. Phases of ice flow imparted multiple sets of glacially streamlined landforms and erosional paleo-flow indicators on the landscape. However, the dominant
eastward-trending, elongated streamlined landforms were formed by ice streaming during deglaciation. Multiple sets of discordant meltwater channels were formed from both an early phase of deglaciation, which fed into an eastward-trending esker
network, and a subsequent late-phase ablation of the ice sheet, with north-south trending channels parallel to the retreating ice margin. Glaciolacustrine strandlines and littoral sediments within the upper George River basin mark the former
northeastern extent of inundation of the earliest phase of glacial Lake Naskaupi. |
| Summary | (Plain Language Summary, not published)
This surficial geology map outlines the glacial history and surficial deposits of the eastern Core Zone region, in the headwaters of the George River and
is a product of the GEM2 Core Zone Surficial Activity that was undertaken in the region (2014-2016). This map provides baseline information that supports future exploration, land-use planning and potentially infrastructure. |
