Record #86041:

Sediment deformation beneath glaciers: rheology and geological consequences / Geoffrey S. Boulton, Richard C.A. Hindmarsh.

Title: Sediment deformation beneath glaciers: rheology and geological consequences / Geoffrey S. Boulton, Richard C.A. Hindmarsh.
Author(s): Boulton, Geoffrey S.
Hindmarsh, Richard C. A.
Date: 1987.
In: Journal of Geophysical Research. (1987.), Vol. 92(B9) (1987)
Abstract: Paper presented at Chapman Conference on Fast Glacier Flow: Ice Streams, Surging, and Tidewater Glaciers, held at Whistler Village, BC, Canada, 4-8 May 1986. Water pressures in till are less than ice pressures and it is suggested that this may lead to infiltration of ice into sediment, which inhibits sliding at interface. Where water pressures are equal or near to ice pressures this does not occur and sliding of glacier may result. Examines these processes in attempt to develop flow laws for subglacial till.
