MARC recordDeforming-bed origin for southern Laurentide till sheets? / Richard B. Alley.
| Title: | Deforming-bed origin for southern Laurentide till sheets? / Richard B. Alley. |
| Author(s): | Alley, Richard B. |
| Date: | 1991. |
| In: | Journal of Glaciology. (1991.), Vol. 37(125) (1991) |
| Abstract: | Widespread, uniform till sheets of southern margin of ice sheet were deposited by fast-moving, wet-bedded ice over relatively short periods of time. Characteristics of till sheets are consistent with deposition from deforming, subglacial sediment layers; difficult to explain origin through debris transport in basal ice. Careful estimation of debris budgets and studies of sorted sediments contained in till sheets may clarify this. |
