Sources of shore sediment on the north coast of Tasmania

Abstract

Following a conclusion that beach sands on the north coast of Tasmania have been subjected to little longshore translocation, an attempt is made to establish their immediate provenance by examining a range of sedimentological characters. It is concluded that most of the sand body was immediately derived from the shelf at and after the postglacial marine transgression. Almost all of the remainder was supplied in the last 6000 years by erosion of coastal bedrock or accession of biogenic carbonate, with little or no contribution from the rivers.
