AbstractThis study is part of the Canada-Nunavut Geoscience Office's Hall Peninsula Integrated Geoscience Program, a multiyear bedrock and surficial geologymapping program. This paper presents the surficial geology component of the program conducted during the 2013 field season, completing a two-year program covering NTS map areas 25I, J, O, P, 26A and B at a scale of 1:100 000. A 1:50 000 scale segment of the surficial geology map for the peninsula, containing all key material types, is presented in this paper. Till and glaciofluvial sediment samples were collected to help understand regionalmineral potential. Till geochemistry and heavymineral results from summer 2012 are briefly presented, the full dataset is available in a separate publication. Glaciodynamic indicatorsweremapped to provide a regional understanding of ice-flow history on Hall Peninsula. Cold-based (limited glacial erosion, regolith material is present), intermediate cold-based (weak to moderate glacial erosion, amix of till and regolith is dominant) andwarm-based zones (moderate to strong glacial erosion, till and bedrock outcrops are abundant) are the principal glaciodynamic zonesmapped. Along the coast, areas with linear selective erosion were also mapped, where fiords and U-shaped valleys are common features.
Summary(Plain Language Summary, not published)
The summer 2013 surficial geology component of the Hall Peninsula project, was led by the Canada-Nunavut Geoscience Office, with colleagues from the University of Waterloo, Centre d¿études Nordiques (Université Laval) and Dalhousie University. The main natural processes that have influenced the landscape on Hall Peninsula are chemical weathering, glaciations, periglacial activity and fluvial erosion. The main scientific objectives of the surficial geology component are to gather information about the nature and distribution of surficial deposits, sample glacial sediments (till) to help regional mineral exploration and provide further understanding on the history of paleo-glacier activity. The intensity, direction and chronology of paleo-ice flows are important for the use of till geochemistry and mineralogy in mineral exploration. The overall outcomes of the project will be useful for road building planning, gravel resources assessment and other aspects of geotechnical studies.
