Online_Linkage: Description: Abstract: The Quaternary geology component of the Slave Province National Mapping Programme (Slave NATMAP) was designed to provide a regional framework for geologic interpretation, environmental management, and drift prospecting. The project involved helicopter-assisted ground work including terrain mapping, till sampling, pebble provenance studies, and measurement of ice flow indicators. Field traverses and airphoto interpretation provided information on the nature and distribution of surface materials shown on the map. About 195 till samples of 2 kg were collected from mudboils. All samples were analyzed for till geochemistry, and some were selected for textural analysis, and determination of water contents and Atterberg indices; 47 additional 10 kg till samples were collected for heavy mineral and kimberlite indicator analyses. Pebble samples were also collected to assess ice flow patterns and glacial transport distances. Maps were constructed using 1:60 000 scale airphotos and recompiled onto a 1:125 000 scale base. Open File 3085 (Dredge et al., 1995) is a preliminary version of the surficial geology map. Purpose: Supplemental_Information: Data set is in English.
