AMS Radiocarbon Dating of Large Za Baobabs (Adansonia za) of Madagascar

The article reports the radiocarbon investigation of Anzapalivoro, the largest za baobab (Adansonia za) specimen of Madagascar and of another za, namely the Big cistern baobab. Several wood samples collected from the large inner cavity and from the outer part/exterior of the tree were investigated by AMS (accelerator mass spectrometry) radiocarbon dating. For samples collected from the cavity w...

Ams Radiocarbon Dating of an Ancient Pottery Workshop in Hepu County, China

An ancient pottery workshop belonging to the Han Dynasty was excavated in Caoxie village, Hepu County. Caoxie village is an important archaeological site in Hepu County, Beihai City, in south China’s Guangxi Zhuang Autonomous Region. It is believed that Hepu County was the oldest departure point on the ancient maritime trading route during the Han Dynasty (206 BC to AD 220) due to the ideal nat...

Pushing the limits of AMS radiocarbon dating with improved Bayesian data analysis

An improved version of the CAR model, the Bayesian data-analysis model for AMS, is presented. Measurement error is taken to be Poisson distributed, improving the analysis for samples with only a few counts. This in turn enables pushing the limit of radiocarbon measurements to lower concentrations. On the computational side, machine drift is described with a vector of parameters and hence the us...

Radiocarbon Dating of Ground Water

Radiocarbon dating of ground water is used in combination with the primary measurements of classical hydrological and chemical analyses. Radiocarbon dating will produce the best results when it involves multiple measurements or sequential sampling. The most useful data come from these comparisons and not from absolute ages. In the case of multiple measurements, the apparent ages of the ground w...
