Ngarrawa (mound spring) sediments as archives of Holocene environmental change in arid central Australia: Insights from Itrax XRF scanning

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate and ‐environmental archives in a region where many aspects of past climate ...

A Vinča potscape: formal chronological models for the use and development of Vinča ceramics in south-east Europe

open access: yesDocumenta Praehistorica, 2016
Recent work at Vinča-Belo Brdo has combined a total of more than 200 radiocarbon dates with an array of other information to construct much more precise narratives for the structural history of the site and the cultural materials recovered from it.

Radiocarbon dates of mammoth finds in Finland compared with radiocarbon dates of Weichselian and Eemian deposits [PDF]

open access: yesBulletin of the Geological Society of Finland, 1979
In Finnish Lapland the Weichselian Peräpohjola Interstadial can be separated from the Eemian Interglacial with the help of the tree pollen composition of organic deposits between tills.

Electron probe microanalysis of extremely fine‐grained tephras: new protocols and insights for analyses at the 1 μ ${\rm{\mu }}$m scale

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Volcanic ash (tephra) provides an important chronostratigraphic framework for correlating Quaternary records. In ultra‐distal ( > $\gt $1500 km) settings such as ice cores and marine sediments, deposits are typically preserved as cryptotephra composed of glass shards ≤ 20 μ $\le 20\,\mu

Use of three isotopes to calibrate human bone radiocarbon determinations from Kainapirina (SAC), Watom Island, Papua New Guinea [PDF]

open access: yes, 2005
In archaeological dating, the greatest confidence is usually placed upon radiocarbon results of material that can be directly related to a defined archaeological event.

Radiocarbon chronology of Andean khipus

open access: yesOpen Journal of Archaeometry, 2014
Unlike every other high civilisation of the ancient world, the Incas did not develop a system of writing based on graphic signs on twodimensional surfaces. Rather, Inca administrative records took the form of three-dimensional knotted-cords made of spun and plied fibers. It is widely believed that khipu technology associated with the rise and expansion

New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core
