Aeolian sedimentation and climate variability during the late quaternary in southeast Queensland, Australia
A 25000 yr record of aeolian sedimentation for coastal southeast Queensland, Australia is presented from Native Companion Lagoon, North Stradbroke Island. Using the easily distinguished geochemistry of the local quartz sands, we reconstruct the first terrestrial record of both local and far traveled...
