Archaeological bone can show marked and complex alterations, both structural and chemical, depending on the environment in which it was buried. Those structural and chemical alternations have an important effect on the result of radiocarbon dating. Our study was based on well-preserved skeletal material from the Ocnam-ri cultural site in Seocheon. In this study we tested by three different collagen extraction methods (improved collagen extraction by modified Login method). Our study shows that there is a difference in the data consistency among the three methods. To our understanding of chemical and physical properties of bone collagen, we tried various analysis such as HI (histological) index, EA (Elemental Analyzer), FT-IR (Fourier transform infrared).
