The recent establishment of a minimum age estimate of 39.9 ka for the origin of rock art in Sulawesi has challenged claims that Western Europe was the locus for the production of the world's earliest art assemblages. Tantalising excavated evidence found across northern Australian suggests that Australia too contains a wealth of ancient art. However, the dating of rock art itself remains the gre...

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. There has been considerable technological development in the last few years – in instrumentation, in the preferred mineral, and in various measurement protocols. New approaches to the latter, espec...

In our isochron studies using grains of different sizes, we observed that the IRSL ages obtained from K‐feldspar without correction for fading show an increase with increasing grain size [Li et al., 2007, 2008]. Huntley [2011a] argued that this result was caused by different fading rates for grains of different sizes or by different source materials for different sizes of grains. We replied to ...

Abandoned shorelines are an important archive used to constrain past fluctuations in the hydrological balance of lakes around globe. Within Australia, preserved at Lake George, NSW, form one few shoreline archives south-east continent that record palaeoenvironmental conditions throughout late Quaternary. Here, we examined and tested lake-level for George constructed 1970s by dating a well-prese...

The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years. Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenla...

Loess deposits distributed in southeastern China play an important role for paleoclimate reconstruction of the subtropical regions. These loess-paleosol are mainly spread within middle and lower reaches Yangtze River as well drainage area Huai River. The ages loess paleosol sequences that along not constrained. In this study, standard single-aliquot regenerative dose (SAR) optically stimulated ...
