Description

Evolution of aridity in the Red Centre expressed in linear dunes. This project aims to understand how the linear dunes that cover one third of Australia’s surface record the history of aridity in the Red Centre over the last 125 thousand years. Correct interpretation of these records is highly significant as there are very few alternative ways to infer the environmental conditions during population of the continent and megafaunal extinction. Expected outcomes of this project are to revaluate the history of aridity in Australia’s interior from the sand grains and layers inside the dunes by developing new computational and laboratory techniques. This project will benefit Australia by providing new, robust environmental context for late Quaternary history in the arid interior.. Scheme: Discovery Projects. Field: 3705 - Geology.
