AbstractIn the summer of 2019, fieldwork was conducted in the Jungersen River area located on northwestern Baffin Island, Nunavut, to document glacial dynamics at a regional scale and mineral prospectivity using till sampling. Field-based glacial geomorphology observations have been integrated with elements from previous surficial geology maps and field observations, and the analysis of pebble lithology in till samples. Laboratory work was performed on the till samples, including geochemical, heavy minerals and sedimentological analyses. Mineral exploration potential was found for diamonds in the study area and for white and translucent corundum south of the study area. The geochemical and mineralogical data will complement existing baseline data to guide any potential future mineral exploration and infrastructure studies in the region.
Summary(Plain Language Summary, not published)
This project involved the study of the glacial sediments and landforms located in the Jungersen River area within northwestern Baffin Island. During summer 2019, samples of sediment deposited by glaciers (till) were collected to evaluate the mineral potential of the region, and glacial striations and landforms left by glaciers were mapped to reconstruct the glacial history. Laboratory work was conducted including analyses of grain size, rock types, geochemistry and heavy minerals. The results will help to guide future mineral exploration and infrastructure studies (permafrost and geotechnical) in the area. The region displays mineral exploration potential for diamonds and corundum.
