Abstract: Palaeodietary reconstruction through elemental analysis has been of great concern in bioarchaeology. However, bone diagenesis, or bone contamination, during long\|term burial would have great impact on the elemental contents of bones. Therefore, identification and exclusion of contaminated bones become a prerequisite before elemental analysis. In this paper elemental contents of 18 human bones in Xigongqiao Site, Tengzhou, Shangdong, were analyzed to monitor bone diagenesis. The Ca/P ratios and contents of Ca and P in XM29, XM 34, XM48, XM38, XM49, XM22, XM41, XM28, XM8 and XM42 indicated the loss of hydroxylapatite integrity. Contents of Al and Fe and their correlation, correlation of Ba and Mn and correlation of lg(Sr/Ca) and lg(Ba/Ca) in the left samples showed that they were contaminated by attack of soil and microorganism. So systematic indicators of bone diagenesis were set up and implied that all the samples were contaminated to some extents and can not be used for palaeodietary study.

Key words: Biopurification, Palaeodiet, Bone diagenesis, Sr, Ba
