Extent of the Late Cainozoic periglacial domain in southwest Tasmania, Australia

Description :
Examination of colluvium mantles and associated alluvial fans along a low altitude transect extending 65 km through western and south-western Tasmania indicates there to have been negligible development of these features inside the ice limits attained during the most recent glacier advance, but that progressively thicker accumulations occur inside successively older glacial limits. This juxtaposition of moraines and slope mantles suggests that most slope instability occurred during episodes of cold climate in response to periglacial processes. Rock rubble in the entrances to some extraglacial karst caves is also interpreted as the product of periglacial frost action.
