L’application de la datation par le carbone 14 pour déterminer la géochronologie des sites archéologiques est. La spectrométrie de masse a rendu la datation par le carbone 14 la méthode la plus précise pour déterminer la mort d’organismes vivants ayant eux lieux au cours des 50,000 dernières années. Plus précisément, cette revue se concentrera sur la possibilité que les estimations d’âge apparentes soient exagérées par la présence de réservoirs de carbone et de restes organiques recyclées, sur la diagenèse d’isotopes de carbone dans les écologies de p H variables, et sur les climats chauds et humides ainsi que les archives sans température contrôlée qui peuvent compromettre l’efficacité des échantillons.

Les âges radiocarbone basés sur des données anciennes doivent être rigoureusement examinés pour en déduire la méthode employée dans la détermination d’âge.

Dr Umberto Esposito, a postdoctoral research in the laboratory of Dr Eran Elhaik, Department of Animal and Plant Sciences at the University of Sheffield, Sheffield, UK, will tell the annual conference of the European Society of Human Genetics today (Monday) that TPS can calculate the mixtures of DNA deriving from different time periods to estimate its definitive age.

"This introduces a completely new approach to dating.

However, the method is not without limitations and this review article provides Africanist archaeologists with cautionary insights as to when, where, and how to utilize radiocarbon dates.

Specifically, the review will concentrate on the potential of carbon reservoirs and recycled organic remains to inflate apparent age estimates, diagenesis of carbon isotopes in variable p H ecologies, and hot-humid climates and non-climate-controlled archives that can compromise the efficacy of samples.

Radiocarbon technology requires certain levels of radiocarbon on the skeleton, and this is not always available.The application of radiocarbon dating to determine the geochronology of archaeological sites is ubiquitous across the African continent.Accelerator mass spectrometry has made radiocarbon dating the most precise method to determine the death of living organisms that occurred within the last 50,000 years." This permits us to open a powerful window on our past.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty of accuracy. In historical geology, the primary methods of absolute dating involve using.… continue reading »
