Glacial Deposition
Two main groups of
landforms are recognised that result from deposition by ice:
- glacial forms, deposited directly from ice
- glacifluvial forms, deposited by meltwater
Shetland is
predominantly a landscape of glacial erosion and most debris has been transported
offshore. Nonetheless examples from both
groups of depositional landforms are represented in the valleys of Shetland where melting
ice masses dumped material during deglaciation. These landforms may be also be
classified in terms of their position relative to the former valley glacier, as subglacial, englacial, supraglacial, marginal and proglacial landforms.
