| Abstract | The surficial geology represented in this map has been prepared at 1:50 000 scale and published at 1:100 000 scale. The surficial deposits cover approximately 65% of the map-area. About 40% of the total
surface is covered by till (units Tb, Tv, Tp, Td, Tr, Tm, Tx). Lacustrine (units Lp, Lb, L v, Lm and Lx) deposits cover ~7% of the area corresponding to "glacial Lake Redstone". About 15% 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 2% of the map area forming terraces along the Dahadinni River, Marten Creek, and a northern tributary to Root River that
drains between Dusky and Rouge ranges. About 2% are alluvial deposits (units Ap, Af and Ax). Peat deposits cover ~2%. Bedrock covers ~ 32% of the map area. It is represented mainly by Devonian shale, limestone and sandstone, and minor Ordovician and
Silurian dolomite. |
| Summary | (Plain Language Summary, not published)
Dahadinni River map area (95-N/SW) is a terrain located along the eastern edge of the Mackenzie Mountains, Northwest Territories and 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 represented only in restricted areas. |
