AbstractPreliminary surficial geology studies, based on air photo interpretation and limited field data, were undertaken in the Daly Bay South map area (NTS 56-A, south) to provide an understanding of the distribution and nature of surficial materials, and regional glacial history. Much of the area is underlain by folded and faulted bedrock containing shallow glacially scoured lake basins. Striae and glacially-moulded bedrock surfaces indicate regional ice flow toward the southeast and late flow south into Daly Bay. Prevalent till veneers and blankets form drumlinoids oriented southeast. Esker systems and substratified deposits developed in well-defined subglacial meltwater corridors oriented parallel to regional and late ice flow directions. Flat-topped eskers suggest they developed late in the glacial cycle, when the ice was thin. Sandy to bouldery marine sediments extend inland to elevations of 140 m (trimline in west) to 150 m a.s.l. (delta in east). De Geer moraines indicate northward ice retreat north of Daly Bay.
Summary(Plain Language Summary, not published)
The Surficial geology Daly Bay South, Nunavut map (NTS 56A-South) identifies surficial materials and associated landforms left by the retreat of the last glaciers to have covered the area about 6000 years ago. The surficial geology is based on aerial photograph interpretation and limited fieldwork. This work was undertaken to provide new geological knowledge and improve our understanding of the distribution, nature and glacial history of surficial materials. This contributes to effective mineral exploration and supports informed decision making for resource development and land use.
