Refining Chronologies by new Radiocarbon Dating Methods: Towards Molecular Isotope Archaeology (F05)

点击翻译按钮获取中文摘要

Understanding human evolution can be considerably improved when studying the isotopic composition of ancient bones providing valuable age and dietary information relevant to all CRC projects. However, bone collagen employed in age and dietary studies is often contaminated due to various geo-chemical processes. While standard protocols in collagen extraction do not sufficiently solve this problem, the application of a newly developed collagen purification method (isolation of individual amino acids) is able to circumvent such contaminations, ultimately providing more reliable results than previous methods. Additionally, the F5 project will continue performing AMS 14C analysis for all CRC projects.
