Overview

regelation


Show Summary Details

Quick Reference

A process by which water that has been released by pressure melting beneath a temperate glacier is refrozen (see also basal sliding; and ice). The process takes place in a relatively thin zone, the ‘regelation layer’, which may be only a few centimetres thick. Regelation is associated with the incorporation of bedrock materials in the debris-rich ‘sole’ of the glacier, which is restricted to the thickness of the regelation layer.
