Thermoluminescence dating of coastal dune sand related to a higher stand of lake woods, Northern Territory

Abstract

A thermoluminescence age of about 20 000 years (± 3 000) B.P. has been obtained for samples of dune sand from near Lake Woods. This gives the time when the sample was last exposed to direct daylight, and it dates a period of dune building associated with an ancestral Lake Woods. The age is compatible with geomorphological evidence.
