AbstractThe surficial geology represented in this map has been prepared at 1:50 000 scale and published at 1:100 000 scale. Surficial deposits cover approximate 95% of the map area. Exposed bedrock covers approximately 5% of the map-area. About 45% of the total surface is covered by till (units Tb, Tv, Tp, Td, Tr, Tm, Tx, Te). Lacustrine (units Lp, Lb, Lv, Lm, Lx) deposits cover 13% of the map-area and are widespread within valleys, but are also heavily colluviated. About 32% of the area is covered by slope deposits (units Cv, Cx and Cz) the main component being landslide deposits (unit Cz). Glaciofluvial sediments (units Gt, Gp, Gd, Gf, Gv and Gx) cover about 3% of the map area, forming terraces along the trench and English Chief River and its tributaries. About 7% of the map area is covered by alluvial deposits (units Ap, Af, Ax). Peat deposits cover ~0.01%.
Summary(Plain Language Summary, not published)
Root River map area (95-K/NE) is a terrain located on the central part of the Mackenzie Mountains foothills between Root and North Nahanni rivers, Northwest Territories. It is part of the Southern Mackenzie Corridor. The present map is a surficial geology map published at 1:100 000 scale. The surficial material/sediments mostly represent glacial deposits associated with the Laurentide glaciation in northwest Canada as well as montane and Cordilleran glaciations during the Late Pleistocene. Glacial sediments of older ages are well represented as cirques in the central part of the map.
