Abstract

Bedrock-geology mapping was conducted in the summer of 2016 in the Tehery Lake–Wager Bay area on the northwestern coast of Hudson Bay, Nunavut, as part of a multiyear, multidisciplinary mapping campaign led by the Geological Survey of Canada, through Phase 2 of the Geo-mapping for Energy a nd Minerals program (GEM-2), and the Canada-Nunavut Geoscience Office. Fieldwork resulted in the identification and spatial constraint of rock units in the northern and western parts of the study area, which were sampled for geochemical, g eochronological and petrographic analysis, as well as to as- sess their economic potential. Mapping has revealed the presence of a large granulite-facies metamorphic domain in the southern part of the study area; the possibility of two different supracrustal rock sequences; the western continuations of the Chesterfield fault zone and Wager shear zone; and generally high, but locally variable, peak metamorphic conditions across the study area. Further analytical work is required to fully characterize rock units, compare and correlate them with other well-studied units, and determine the geological history and economic potential of the Tehery Lake–Wager Bay area.
