Record #123985:
Pleistocene stratigraphy, paleopedology, and paleoecology of a multiple till sequence exposed on the Little Bear River, western District of Mackenzie, N.W.T. / O.L. Hughes, C. Tarnocai, C.E. Schweger.
Title: | Pleistocene stratigraphy, paleopedology, and paleoecology of a multiple till sequence exposed on the Little Bear River, western District of Mackenzie, N.W.T. / O.L. Hughes, C. Tarnocai, C.E. Schweger. |
Author(s): | Hughes, O. L. Tarnocai, C. Schweger, C. E. |
Date: | 1993. |
In: | Canadian Journal of Earth Sciences. (1993.), Vol. 30(4) (1993) |
Abstract: | Sequence of five glacial tills separated by palaeosols and organic deposit is interpreted as long record of glacial--interglacial cycles. Interglacial conditions appear to have been were warmer than and as dry as, or drier than, present. Permafrost was absent or active layer was significantly deeper, and boreal forest developed upslope beyond present limit. Little known about rate of climatic warming or duration of interglacial intervals. |
