Surficial geology, Dahadinni River, Northwest Territories, NTS 95-N northwest / author, A. Duk-Rodkin. : M183-1/298-2016E-PDF
"The surficial geology represented in this map has been prepared at 1:50 000 scale and published at 1:100 000 scale. Surficial glacial deposits occupy approximately 95% of the map area. The other 5% of the map area is covered by exposed bedrock represented mainly by Devonian shale, limestone, sandstone, and minor Ordovician and Silurian dolomite, and Cretaceous sandstone and shale. Till deposits (units Tb, Tv, Tp, Td, Tr, Tm and Tx) represent about 60% of the surficial deposits. Lacustrine (units Lp, Lb, Lv, Lm, Lx) sediments represent about 12% of the surficial cover. About 13% of the area is covered by colluvial deposits (units Cv, Cx) most of which constitute landslides (unit Cz). Glaciofluvial sediments (units Gt, Gp, Gd, Gf and Gx) form about 5% of the surficial deposits and include prominent terraces along the Redstone and Dahadinni rivers. Alluvial deposits (units Ap, A f, Ax) cover about 3% of the map area. Peat deposits cover about 2%"--Abstract.
