AbstractThe Rivière De Pas area is of moderate relief, characterized by extensive till blanket units in lowlands and till veneer units and bedrock outcrops at higher elevations. The region was differentially eroded by the Laurentide Ice Sheet throughout Wisconsin time, largely influenced by the migration of the Ancestral Labrador Ice Divide, originally from east of the De Pas batholith to west of the map area. Phases of radial ice flow from the migrating ice divide imparted discordant erosional ice-flow landforms and flow indicators on the landscape. Significant regions of bedrock at higher elevations have been washed of till from late-phase ablation of the ice sheet during deglaciation, with associated small meltwater channels. Below 425 m elevation, the region was inundated by glacial Lake McLean, a proglacial lake that occupied the lowlands in the northwest. Sediments from glacial Lake McLean are limited to littoral beach deposits and winnowed till surfaces.
Summary(Plain Language Summary, not published)
Surficial geology map for the De Pas River region of northern Quebec. This map provides the regional baseline information on surficial materials suitable for exploration, resource planning, environmental surveys and land-use planning.
