'Paraglacial' - means unstable conditions (as defined by Renwick, 1992) caused by a significant relaxation time in processes and geomorphic patterns following glacial climates (Church and Ryder, 1972).
When a large mass of ice melts, other factors such as the
ecological communities, sediment
deposition patterns and the
earth's crust need time to accommodate themselves to the new conditions.
