Silcrete was often used to make stone tools and the ubiquity of this material in the archaeological record has sparked considerable interest in developing techniques that can be used to trace its geographic origin. However, the highly variable physical and chemical properties of silcrete means that artefacts made from this raw material have proved difficult to provenance. This paper describes the use of Pb isotope analysis to characterize and differentiate silcrete sources in the Willandra Lakes region, a UNESCO World Heritage listed site in southeastern Australia. The sample collection strategy employed in the field has allowed Pb isotope variation both within and between the silcrete sourc..View full abstract

We thank the Barkindji/Paakantji, Ngyiampaa and Mutthi Mutthi Elders for their support of this research. We are particularly indebted to Daryl Pappin, the Cultural Heritage Officer employed by the umbrella research project, Kate Barnes, a Willandra Lakes local, and Caroline Spry from La Trobe University, for their assistance in the field. The samples were collected in accordance with a Review of Environmental Factors granted by the New South Wales Office of Environment and Heritage. Special thanks to Warrick Joe for his thorough, careful and cheerful preparation of all the silcrete samples and to Bence Paul and Jon Woodhead for their discussion of Pb isotopes.
