Radiocarbon dating of Quaternary groundwater in the North China Plain and its implication to 14C correction

Shuiwen dizhi gongcheng dizhi
14C is commonly used in groundwater dating. Due to the uncertainty of the initial 14C contents (A0) and the complex geochemical processes in the subsurface, the 14C ages were corrected but remain largely uncertain.

Comparison of 14C and 230Th/234U Dating of Speleothems from Submarine Caves in the Adriatic Sea (Croatia)

Acta Carsologica, 2016
Z metodama 14C oziroma U-Th smo datirali 16 sig iz sedmih podmorskih jam v Jadranu. Dve sigi smo datirali z obema metodama. Primernost metod za datacijo sig je različna zaradi različnih okoljskih pogojev, ki so vladali med izločanjem sige oziroma po ...

Characterisation of a new protocol for mortar dating: 14C evidences

Open Journal of Archaeometry, 2014
Mortars represent a class of material basically constituted by a mixture of different phases (<em>i.e.</em> binder, aggregates, water) and widespread used for constructive uses and artworks. Current scientific literature regarding the possibility of mortar radiocarbon dating reports different and still contradictory results.

Tree rings reveal globally coherent signature of cosmogenic radiocarbon events in 774 and 993 CE

Nature Communications, 2018
Despite their extensive use, the absolute dating of tree-ring chronologies has not hitherto been independently validated at the global scale. Here, the identification of distinct 14C excursions in 484 individual tree rings, enable the authors to confirm ...

Including Explicit Priors on Phase Duration in Bayesian 14C Dating

Documenta Praehistorica, 2021
Bayesian modelling of radiocarbon dates directly integrates information obtained through archaeological analysis. Here, I explain how to add known information/reasonable assumptions about the length of a deposition phase, using the example of date

A North Greenland‐wide in situ cosmogenic 14C ice sheet chronology since the Lateglacial

Boreas
Knowledge of the glacial history of the North Greenland Ice Sheet is crucial due to its high sensitivity to climate change. However, because the ice sheet in this region is predominantly cold‐based, resulting in low erosion rates, using 10Be exposure ...

Phoenician ceramic tableware between East and West: some remarks on open forms and on their absolute chronology

Cartagine. Studi e Ricerche, 2017
In this paper a typological and chronological framework of the evolution of open forms of the Phoenician table pottery is outlined, starting from the Iron Age documentation of the Syro-Palestinian coast (11th-6th centuries BC) up to the colonial ...

Source Criticism or Dilettanti? Some thoughts on "Scandinavia's Oldest House" in Tingby near Kalmar, Småland

Current Swedish Archaeology, 1993
ln a number of articles the so-called Tingby House is presented as a feature from the Boreal Period, a sensationally early date for so distinct a house remnant.

Radiocarbon and Luminescence Dating of Lacustrine Sediments in Zhari Namco, Southern Tibetan Plateau

Frontiers in Earth Science, 2021
There are more than 1,000 lakes within the Tibetan Plateau (TP), all of which are sensitive to changes in regional climate and local hydrology. Lacustrine sediments within these lakes preserve a good record of these changes.
