Journal ArticleDOI
Optical dating of single and multiple grains of quartz from jinmium rock shelter, northern australia: part i, experimental design and statistical models*
TL;DR: In this paper, the authors outline the background to the optical dating program at Jinmium, and describe the experimental design and statistical methods used to obtain optical ages from single grains of quartz sand.
Journal ArticleDOI
New ages for human occupation and climatic change at Lake Mungo, Australia
J. M. Bowler,Harvey Johnston,Jon Olley,John R. Prescott,Richard G. Roberts,Wilfred Shawcross,Nigel A. Spooner,Nigel A. Spooner +7 more
TL;DR: A new chronology corrects previous estimates for human burials at this important site and provides a new picture of Homo sapiens adapting to deteriorating climate in the world's driest inhabited continent.
Journal Article
Precision and accuracy in the optically stimulated luminescence dating of sedimentary quartz: a status review
Andrew S. Murray,Jon Olley +1 more
TL;DR: Optically stimulated luminescence (OSL) dating of light-exposed sediments is used increasingly as a mean of establishing a sediment deposition chronology in a wide variety of late Quaternary studies as mentioned in this paper.
Journal ArticleDOI
New Ages for the Last Australian Megafauna: Continent-Wide Extinction About 46,000 Years Ago
Richard G. Roberts,Timothy F. Flannery,Linda K. Ayliffe,Hiroyuki Yoshida,Jon Olley,Gavin J. Prideaux,Geoff M. Laslett,Alexander Baynes,Mike Smith,Rhys Jones,Barton L. Smith +10 more
TL;DR: This work reports burial ages for megafauna from 28 sites and infer extinction across the continent around 46,400 years ago, ruling out extreme aridity at the Last Glacial Maximum as the cause of extinction, but not other climatic impacts; a "blitzkrieg" model of human-induced extinction; or an extended period of anthropogenic ecosystem disruption.
Journal ArticleDOI
The distribution of apparent dose as determined by Optically Stimulated Luminescence in small aliquots of fluvial quartz: Implications for dating young sediments
TL;DR: In this paper, the authors examined the distribution of apparent dose in small aliquots (each composed of ∼2000 grains) of different particle size fractions (63-90μm, 90-125mm, 125-180mm, 180-212mm, and 250-250mm diameter) from two samples collected from the Murrumbidgee River, New South Wales, Australia.
