Abstract

Thermoluminescence dating of quartz sand (90-125 μm) from the coastal barrier successions between Phan Thiet and Tuy Phong, southeastern Vietnam, reveals that a substantial component was deposited during the last interglacial sensu lato (Oxygen Isotope Stage 5) between 108 and 85 ka. The barrier successions have subsequently, in places, experienced multiple phases of aeolian reworking during the last glacial cycle, and in particular between 62 and 19 ka, possibly related to reduced vegetation cover and landscape instability caused by climatic change. The difficulties of applying the thermoluminescence (TL) method in areas of intense tropical weathering are also examined.
