Holocene variations in the Scottish marine radiocarbon reservoir effect [PDF]

, 2004
We assessed the evidence for variations in the marine radiocarbon reservoir effect (MRE) at coastal, archaeological Iron Age sites in north and west Scotland by comparing AMS measurements of paired marine and terrestrial materials (4 pairs per context ...

Modelling medieval masonry construction: taxa-specific and habitat-contingent Bayesian techniques for the interpretation of radiocarbon data from Mortar-Entrapped Relict Limekiln Fuels

Heritage Science, 2021
Using data from simulated and actual case studies, this paper assesses the accuracy and precision of Bayesian estimates for the constructional date of medieval masonry buildings, generated from the radiocarbon evidence returned by different assemblages ...

Calibration of Radiocarbon Ages by Computer [PDF]

Radiocarbon, 1989
A PC-based computer program for automatic calibration of 14C dates has been developed in Turbo-Pascal (version 4.0). It transforms the Gaussian 14C dating result on the 3σ level into a real calendar age distribution. It uses as a calibration curve a spline function, generated along the calibration data points as published in the Radiocarbon Calibration

Radiocarbon dating and its applications in Chinese archeology: An overview

Frontiers in Earth Science, 2023
Radiocarbon dating is a well-established chronometric technique that has been widely employed in Chinese archeology since the first radiocarbon laboratory started operating in the Institute of Archaeology at the Chinese Academy of Sciences in 1965.
