Errors carbon 14 dating
Legacy radiocarbon ages must be critically examined for what method was used to generate the age, and calibration radiocarbon ages from critical periods of African prehistory lack precision to resolve significant debates.
A multipronged dating strategy and careful selection of radiocarbon sample materials are advocated from the earliest stages of research design. Cette revue fournit les archéologues africanistes avec des appréciations et des mises en garde sur l’utilisation des âges radiocarbone.
Accuracy refers to how close the assessed age of a sample is to the true age.
Precision refers to the statistical uncertainty associated with an age estimate—the greater the precision, the less uncertainty there is in the assessed age.
The application of radiocarbon dating to determine the geochronology of archaeological sites is ubiquitous across the African continent.
Les âges radiocarbone basés sur des données anciennes doivent être rigoureusement examinés pour en déduire la méthode employée dans la détermination d’âge.The factors discussed below are challenges of which all Africanists must be keenly aware, but there are additional considerations that are more generally applicable, yet no less relevant (e.g., Bayliss Diagenesis is a process in which the chemical components of a substance are altered from their primary states.As it applies to radiocarbon dating, diagenesis compromises carbon isotopes as (usually bone) tissues of the decomposing organisms interact with fluids present in soil (Hedges ).Radiocarbon dating is the most frequently utilized method for gaining geochronology on archaeological sites across the world.The general reliability of the method and abundance of sites with carbon-based materials for dating have justifiably propelled radiocarbon dating to the top of the available methods for securing age control on archaeological activity.
