Thermoluminescence dating of dune podzols at Cape Arnhem, northern Australia

Quaternary lithostratigraphic units in coastal dunes have been dated at two locations in the dune fields near Cape Arnhem, northern Australia, using coarse fraction thermoluminescence (TL) dating. Fifteen TL dates were measured. Five main chronostratigraphic units were identified which include a lat...

Description
Summary:Quaternary lithostratigraphic units in coastal dunes have been dated at two locations in the dune fields near Cape Arnhem, northern Australia, using coarse fraction thermoluminescence (TL) dating. Fifteen TL dates were measured. Five main chronostratigraphic units were identified which include a late Pleistocene unit (ca. 19,000 yr), an early Holocene unit (ca. 9000-6500 yr), a mid Holocene unit (ca. 4000 yr) and two late Holocene units (ca. 2100 yr and ca. 1000 yr). These, respectively, have been associated with the deflation of exposed shelf sediments during the last glacial, the disturbance of this material by rising sea level, and climatic variations in the late Holocene.
