Coastal dunes and strandplains in southeast Queensland: Sequence and chronology

Parabolic dunes invade coastal strandplains and overlie prior blown dunes in southeast Queensland. These coastal dune landscapes were produced primarily by real changes in wind strength and frequency. Sand movement began in past glacial ages and in the most recent instance persisted into Holocene time. Four interglacial shores are identified with marine isotope stages 5, 7, 9 and 11, and allow estimation of the ages of the dune and beach sands, by correlation with the EPICA Dome C ice core, as follows: Triangle dune sand, n.d.; Garawongera dune sand, 65 ka; Woorim beach sand, 125 ka; Bribie beach sand, 245 ka; Bowarrady dune sand, 270 ka; Poyungan beach sand, 335 ka; Yankee Jack dune sand, 360 ka; Ungowa beach sand, 410 ka; Awinya dune sand, 430 – 486 ka; Cooloola dune sand, >486 ka.
