ANALYSIS OF HYDROXYAPATITE IN ANCIENT HUMAN BONE USING RAMAN SPECTRA AND XRD
古人类骨中羟磷灰石的XRD和喇曼光谱分析

The skeleton remains of ancient people are the main materials for bioarchaeological research. The identification of bone contamination is not only the basis to pick out the samples but also one of prerequisites for bioarchaeometry. The identification of the bone contamination degree was investigated through analysis of ancient human bone from the Keyaheyuansha site in Sinkiang Uigur Autonomous Region by use of methods of X-ray diffraction (XRD) and Raman Spectra. The results showed that the incorporation of the two techniques accurately revealed the change of crystallinity of hydroxyapatite and could briefly and effectively distinguish the contamination of the ancient human bone.
