Outline of the Talk

Analysis of stable isotope 13C and 15N from human bones is an important method for research on ancient people’s diet. Analysis of 13C can tell us about what the people have in their staple food and analysis of 15N can reflect the nutrition level of the people. In 1980s, analysis of 13C was first introduced in China by the Radiocarbon Dating Laboratory of Institute of Archaeology and human or animal bones from some famous archaeological sites of China such as Yangshao and Taosi were analyzed and it revealed that people had the kind of millet as their staple food and while the pig had bran of millet as their staple food, which started the research in China. In the beginning of the century, on the basis of a lot of experiments, the analysis of 15N was established with the instrument for element analysis in the Laboratory for the first time in China, which completing the method as a whole. Recent years, by this method, many archaeological sites, especially some earlier prehistory sites have been detected on the diet of past and then it also provided the basis for the research on natural environment, development of productive forces and related social customs.
