Abstract

A modern landsystems analogue for plateau icefield glaciation is presented, based upon Tungnafellsjökull in Iceland. Landform mapping and intensive clast form analysis on 3 separate forelands occupied during the Little Ice Age reveal variability in the morphology of moraines and the degree of clast modification, which is interpreted as a function of the complex interplay between: (a) the efficacy of glacial erosion; (b) passive versus active debris transfer mechanisms; and (c) the volume of debris provision for ice-marginal freeze-on mechanisms. A steep outlet bounded by rockwalls produced a landform assemblage and debris transport signature typical of valley glaciers, whereas 2 unconfined outlets produced a landform-sediment imprint typical of polythermal conditions
