The purpose of the underlying study was to identify major periods of dune building over the Pleistocene time period to determine the mechanisms responsible for their formation.\r\n\r\nThis was done using optically stimulated luminescence (OSL) dating which can be used to date the time period when a sand dune was last active. Due to the exceptionally old luminescence ages produced here we also sort additional age control by developing a paleomagnetic stratigraphy of the Cooloola Sand Mass. Paleomagnetic analysis was performed on pieces of ferricrete that have formed in buried soils that allowed us to identify the stratigraphic position of the most recent magnetic reversal which occurred at 773 thousand years ago.\r\n\r\nThe paleomagnetic data includes the demagnetization steps, demagnetization results and the principle component analyses used for interpretation. The OSL data includes site information, equivalent dose results and the chemistry information used for dose rate calculations.\r\n\r\n\r\n\r\n","url":"http:\/\/bolin.su.se\/data\/ellerton-2022-osl-queensland-1","keywords":["Terrestrial","Geochronology","Geochronology","Paleomagnetism","Optically stimulated luminescence","OSL","Dunes","Dating","Fraser Island","Cooloola Sand Mass","Middle Pleistocene Transition","Matuyama\/Bruhnes boundary","Earth science > Land surface > Geomorphic landforms\/processes > Aeolian landforms > Dunes > Parabolic dune"],"creator":{"@type":"Person","name":"Daniel Ellerton, Tammy Rittenour, Andrew Roberts, James Shulmeister, Xiang Zhao, Pengxiang Hu, Tetsuro Sato, Hirokuni Oda"},"citation":"Aitken MJ, Alldred JC (1972) The Assessment of error limits in thermoluminescent dating.
