Record #112074:

Ice-deformation processes from mapping of c-axis fabrics / Anthony J. Gow, Richard B. Alley, Debra A. Meese.

Title: Ice-deformation processes from mapping of c-axis fabrics / Anthony J. Gow, Richard B. Alley, Debra A. Meese.
Author(s): Gow, Anthony J.
Alley, Richard B.
Meese, Debra A.
Date: 1991.
In: Eos : transactions, American Geophysical Union. (1991.), Vol. 72(44, supplement) (1991)
Abstract: AGU Fall Meeting Program and Abstracts, December 9-13, 1991. In Byrd station ice core, grain size increased down to 400 m depth but remained constant over next several hundred metres. Discusses possible mechanisms to stop grain growth. Preliminary measurements show that c-axes in ice from shallower than 400 m in Byrd core have random nearest-neighbour relations, but that deeper ice has non-random fabric with many small misorientations. It thus appears that polygonization causes grain growth to stop there, below 400 m.
