AbstractThis surficial map is based on aerial photographs and satellite images interpretations, as well as on field work observations (Tremblay et al. 2013, 2014 and 2015). The southwestern corner of the NTS 26-B mapsheet was mapped by Leblanc-Dumas et al. (2015). The plateau forms a heteregenous map pattern, with patches of cold-based sediments (regolith, and regolith mixed with till) cross-cut by till deposited during glacial readvances, and glacial lakes sediments. The regolith is a pre-glacial or interglacial landscape feature (Leblanc-Dumas et al., 2015). The northeastern rugged land was eroded by warm-based glaciers flowing toward the northeast, and is dominantly covered by till and bedrock outcrops. The striation data was compiled from Tremblay et al. (2015) and Johnson et al. (2012). The eastern coast was dissected by valley and fiord glaciers. The Frobisher Bay moraine was formed from 9 to 8 14C ka, and the deglaciation of Chidliak Bay is dated at 8.6 14C ka (Miller, 1985; Hodgson, 2005). Proglacial lakes were dammed by important moraines (Frobisher Bay and Hall moraines: Miller, 1985). The observed marine limits range from 60 m asl to 85 m asl.
Summary(Plain Language Summary, not published)
The Canada-Nunavut Geoscience Office, located in Iqaluit, Nunavut, has conducted field work to map the surficial geology of Hall Peninsula. During summer 2013, NTS (National topographic system) map sheet 26B was covered. This map presents different types of surficial sediments, deposited from glaciers, rivers, glacial lakes and marine environments. The valleys are filled with fine-grained and sandy deposits, while the plateau is covered with bouldery material with a sandy matrix. This map will be useful to understand the types of material encountered in the building of infrastructure, likes roads and buildings, and for glacial exploration for mineral resources like diamonds and gold.
