AbstractThe northwest part of the Joe Lake North map area is dominated by glaciated granitic and gneissic bedrock, and small lake basins. The remainder of the area is gently rolling terrain consisting of a major north-trending drumlin field, four esker systems, and marine deposits that lie between the drumlins. Postglacial marine deposits occupy much of the terrain in the north part of the map area. The limit of postglacial marine submergence is at about 180 m a.s.l. in the southwest, and at about 170 m elsewhere, as determined by wave-washed trimlines on drumlins, and several ice-contact deltas on eskers. Well formed beaches are rare, but drumlins have been reworked to varying degrees. Those at higher elevations in the south have been only slightly modified by postglacial seas, whereas those at lower elevations in the north are covered by a veneer of marine deposits.
Summary(Plain Language Summary, not published)
The Joe Lake north map (NTS 66-J north) in Nunavut identifies glacial, glaciofluvial and marine surficial sediments and landforms deposited by the Laurentide Ice Sheet and in the post-glacial sea. The surficial geology is based on the interpretation of aerial photos. This work was undertaken to provide new geological knowledge and improve our understanding of the distribution, nature and glacial history of surficial materials in the Rae Geological Province. The map will support informed decision making for resource development and land use.
