Record #126138:

Microscopic evidence of subglacial deformation / Jaap J.M. van der Meer.

Title: Microscopic evidence of subglacial deformation / Jaap J.M. van der Meer.
Author(s): Meer, Jaap J. M. van der.
Date: 1993.
In: Quaternary Science Reviews. (1993.), Vol. 12(7) (1993)
Abstract: Reviews evidence. Starts with case where deformation could be established macroscopically, then traces microscopic features through planar and rotational movements, which are described and separated accordingly. Attention also given to features caused by crushing of grains and sediment dewatering. These studies indicate that almost all basal tills show evidence of subglacial deformation rather than sedimentary derivation. This implies that, in describing subglacial processes, such tills should be described in tectonic rather than sedimentary terminology.
Notes:
