Short summary

Ice often exhibits a single-cluster fabric when deformed to high strains in glaciers and ice sheets. Using the equal-channel angular pressing technique, we achieved high shear strains in laboratory experiments and examined the fabrics. We investigated the evolutions of fabric and recrystallization mechanisms with strain. The results suggest that rotation recrystallization dominates fabric development when ice is deformed to high strains, explaining the fabrics found in natural ice.
