Glacial history of the upper Pieman and Boco valleys, western Tasmania

Abstract
The surficial deposits of the upper Pieman and Boco valleys of western Tasmania are the result of four glaciations. These glacial episodes are partly differentiated on a morphostratigraphic basis and partly on a chronostratigraphic basis by the application of age‐dependent weathering criteria. The most useful relative‐dating measures are weathering rind thicknesses, percentage absorption of water, specific gravity of rock clasts, degree of till matrix weathering, and post‐depositional modification of glacial landforms.
