| Title: | Origin and stratigraphy of Pleistocene gravels in Dawson Range and suggestions for future exploration of gold placers, southwestern Carracks map area, Yukon Territory / Lionel E. Jackson, Jr. |
| Author(s): | Jackson, Lionel E., |
| Date: | 1993. |
| In: | Geological Survey of Canada. Paper. (1993.), Vol. 93-1A (1993) |
| Abstract: | Placers occur here due to lack of glaciation for over 1 Ma and presence of Late Cretaceous granites and subvolcanic Mount Nansen Group. Quaternary context is discussed: four glaciations are recognized (Nansen, Kaza, Reid and McConnell (youngest)). Placers were created during stream degradation following pre-Reid glaciations. Signiicant aggradation occurred along streams as result of Reid glaciation; subsequent McConnell glaciation had little effect, by comparison. |
