Aridity in the monsoon zone as indicated by desert dune formation in the Gregory Lakes basin, northwestern Australia
Desert dunes within the monsoon-fed Gregory Lakes basin form valuable archives for Quaternary paleoenvironments, in a region where such records are scarce. Optically stimulated luminescence (OSL) chronologies from two dunes identify the timing of eolian processes, interpreted as a complex response to aridification and increased sediment availability during lake transgressions and associated fluvial activity. The earliest eolian deposition in our record occurred ca 91.5 ka, which postdates the...[Show more]
