Abstract

Quantitative studies of relative dating parameters, including subsUlface dolerite
weathering rind thickness and weathering Font penetration, permit the
differentiation of three broad groupings of til! deposits in several valleys in
north-central, western, western-central and south-western Tasmania. An early
cold climatic phase-the Linda Glacial Stage-is recognised on the basis of
this weathering evidence which also indicates that there have been at least two
more recent Glacial Stages of decreasing severity, termed here the Henty and
Margaret Glacial Stages respectively. This three-fold model bears a striking
similarity to that of Lewis (1945) which was rejected nearly three decades ago.
However, whereas Lewis' model was founded upon erosional evidence, the
present study is based entirely upon depositional and weathering evidence.
