Title: Marine transgression and dune initiation on western Cape York, northern Australia
Abstract: The chronostratigraphy of the coastal dunes on the western side of northern Cape York differs from the general pattern of dune emplacement identified on easterly facing coasts across northern Australia. Two episodes of dune emplacement are suggested by morphology prior to the establishment of the modern foredune. TL dating and comparative soil profile development indicate the possibility of three episodes. Based on a small number of TL dates, it is possible to associate dune emplacements at about 11,200 yrs B.P., 8300 yrs B.P. and 5200 yrs B.P. with shoreline disturbance and the destruction of shoreline vegetation by rising sea level. Stabilisation of the 11,200 yrs B.P. unit may be due to a short marine regression roughly around the time of the younger Dryas. The 8300 yrs B.P. unit probably stabilised due to changed environmental conditions, and the 5200 yrs B.P. unit represents the cessation of post-glacial sea-level rise in northern Australia.
