Radiocarbon Dating of Bone [PDF]

open access: yesNature, 1967
SELLSTEDT et al.1 have described a method for the removal of inorganic carbonates from bone so that the residual collagen can be used as a source material for radiocarbon dating, and they conclude that this “offers the archaeologist an elegant and versatile tool which is likely to find wide application”.

Bern Radiocarbon Dates V [PDF]

open access: yesRadiocarbon, 1965
This list includes about half of the samples measured during the last year. Many studies need further investigation and the results will be published later when additional information will make better interpretations possible.The equipment and the technique is essentially the same as described earlier (Bern IV).Reliable results on CO2 samples extracted

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Managing and visualising geochemical data for tephra correlation with the IntChron Integration Tool

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT There is now a wealth of glass‐shard geochemical data for volcanic ash (tephra) layers from a wide range of volcanoes and eruptions, providing invaluable datasets for tephrochronology. However, compilation of published data to assess tephra correlations leads to large files and requires careful management.

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.

New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Archaeological Excavations on the BTC Pipeline, Azerbaijan

open access: yesInternet Archaeology, 2011
The archaeology and history of the Republic of Azerbaijan is not widely known in comparison with that of its neighbours. A recent summary of work in the Caucasus (Smith and Rubinson 2003) contained no specific references to results from Azerbaijan ...

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 ...
