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
