AbstractThe objective of this project is to reconstruct the glacial history and evaluate the mineral potential of the area on the north coast of Fury and Hecla Strait, northwestern Baffin Island, from the study of glacial sediments. Following till sampling conducted in 2018, laboratory work was performed on the samples, including geochemical, heavy minerals and sedimentological analyses. Till compositions were classified between five characteristic lithology groups and compared with the geochemistry of different pebble lithologies. The geochemical and mineralogical data will provide additional baseline data to guide future mineral exploration and infrastructure studies (permafrost and geotechnical) in the region. The region displays mineral exploration potential for uranium, iron and diamonds. A minor, but still uncertain, potential is that for white and clear corundum grains; their presence in till is reported here but further investigation is required to assess their significance.
Summary(Plain Language Summary, not published)
The objective of this project is to study the glacial sediments located north of Fury and Hecla Sound within northwestern Baffin Island. Laboratory work was performed including geochemistry, heavy minerals and sedimentological analysis. It will help to guide future mineral exploration and infrastructure studies (permafrost and geotechnical) in the region. The region displays significant mineral exploration potential for diamonds, uranium and iron. A minor but still uncertain potential for abundant corundum white and clear grains.
