Deformation histories and structural assemblages of glacier ice in a non-steady flow regime / Wendy J. Lawson, Martin J. Sharp, Michael J. Hambrey.
Title: | Deformation histories and structural assemblages of glacier ice in a non-steady flow regime / Wendy J. Lawson, Martin J. Sharp, Michael J. Hambrey. |
Author(s): | Lawson, Wendy J. Sharp, Martin J. Hambrey, Michael J. |
Date: | 2000. |
Publisher: | London: Geological Society |
In: | Deformation of glacial materials. (2000.), |
Abstract: | Uses technique based on evaluation of strain-rate fields from velocity gradients in estimating deformation history of ice at centre of ablation area of Variegated Glacier, Alaska. Shows ice in upper ablation area after 1982-83 surge had one relevant deformation event, whilst ice in terminal lobe had six surge phases in 100 years. Study indicates complexity of relationships between strain rate histories and histories of accumulation of strain as well as between deformation histories and structural assemblages. |
