Abstract

A record is presented of late Quaternary deposits from two sections on the Lumeah
Point Peninsula, Pipe Clay Lagoon. The results permit interpretation of some of the
main geomorphic events and environmental changes that have occurred during the late
Last Glacial and Holocene stages.
Interglacial marine deposits of sand, clayey-sand and gravels are unconformably
overlain by freshwater organic sediments dated to about 25,000-20,000 BP. Pollen
analysis indicates a change in vegetation from Eucalyptus forest to Eucalyptus-savannah
during this time. After 22,000 BP aeolian sands began to accumulate at
Site A and probably continued during the maximum of the Last Glacial stage. Once
stabilised, the aeolian and adj acent marine sands were strongly podzolised during
the Holocene. Aboriginal middens and thin coversands resulting from forest clearance
for agriculture by European settlers occur in and on the A\1 horizon of the podzol.
