Surficial geology and periglacial features, Pangnirtung, Nunavut / [by] A.S. Carbonneau ... [et al.].: M183-1/65-2011E-PDF
"The map of surficial geology and periglacial features in Pangnirtung was done to help decision-makers, planners and engineers to better adapt the community to the impacts of climate change. The dominant surface unit on the map consists of colluvium deposits which are ice-rich sandy sediments deposited by overland-flow during snowmelt. Buried soils as old as 7080 cal BP were found imbedded in a colluvium layer. In the eastern sector of town, colluvium 1 to 4 metres thick covers till and a network of ice wedges. It also covers ice-rich marine silts and bedrock in the western sector. The central sector of town is occupied by a coarse, boulder-rich, Holocene outwash fan deposited by the Duval River. An alluvial terrace with boulders and some eroded channels were incised by the river in the fan. Bedrock and thick till deposits are found in the upper river valley and on the slopes of the fjord"--Abstract.
