Radiocarbon dating — modern state, problem, prospects of development and use in archaeology
Вестник археологии, антропологии и этнографии, 2016 Basic principles of radiocarbon dating are presented in the article. History of the method development and modern state are shown. Difficulties appeared under the radiocarbon dating and approaches, permitting to present the received results correctly are

New hydroxyproline radiocarbon dates from Sungir, Russia, confirm early Mid Upper Palaeolithic burials in Eurasia. [PDF]
PLoS ONE, 2014 Sungir (Russia) is a key Mid-Upper Palaeolithic site in Eurasia, containing several spectacular burials that disclose early evidence for complex burial rites in the form of a range of grave goods deposited along with the dead.

The Effects of Contamination of Calcareous Sediments on their Radiocarbon Ages [PDF]
Radiocarbon, 1986 Two principal reasons for the inherent uncertainty in 14C dating of calcareous sediments such as tufa or those of lacustrine origin are the unknown initial 14C activity (Ao) of the sediment, mainly affecting younger (Holocene) samples, and contamination of older sediments with recent carbonate, causing 14C ages to be excessively young.

Anomalous radiocarbon ages for foraminifera shells [PDF]
Paleoceanography, 2006 The causes for discordant radiocarbon results on multiple species of planktonic foraminifera from high‐sedimentation‐rate marine sediments are investigated. We have documented two causes for these anomalous results. One is the addition of secondary radiocarbon for which we have, to date, only one firm example. It involves an opal‐rich sediment.

MARINE RADIOCARBON CALIBRATION IN POLAR REGIONS: A SIMPLE APPROXIMATE APPROACH USING MARINE20
Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2023 The Marine20 radiocarbon (14C) age calibration curve, and all earlier marine 14C calibration curves from the IntCal group, must be used extremely cautiously for the calibration of marine 14C samples from polar regions (outside ∼ 40ºS–40ºN) during glacial

Radiocarbon in dissolved organic carbon of the Atlantic Ocean
Geophysical Research Letters, 2016 Marine dissolved organic carbon (DOC) is produced in the surface ocean though its radiocarbon (14C) age in the deep ocean is thousands of years old. Here we show that ≥10% of the DOC in the deep North Atlantic is of postbomb origin and that the 14C age ...

Geochronological implications of 210Pb and 137Cs mobility in cave guano deposits
International Journal of Speleology, 2021 Some recent publications on the paleo- and historical environmental interpretation of bat guano sequences have relied on 210Pb and 137Cs distribution to establish age-depth models, even when these are at odds with radiocarbon models in the lower parts of

RADIOCARBON DATING OF THE HISTORIC GRAND BAOBAB OF MAHAJANGA, MADAGASCAR
Studia Universitatis Babes-Bolyai Chemia, 2023 The article reports the AMS (accelerator mass spectrometry) radiocarbon investigation of the historic Grand Baobab of Mahajanga. The largest African baobab of Madagascar exhibits a cluster structure, which consists of 6 fused ordinary stems and of 3 ...
