Summary

The physical survival of the skeleton in the burial environment is vital to any palaeopathological study, and the extent of diagenetic degradation of remains is an important determinant of the quantity and quality of palaeopathological data that can be obtained from an archaeological skeletal assemblage. In this contribution, the chemistry, microstructure and ultrastructure of skeletal tissues are described. The changes wrought in both the inorganic and organic components of hard tissues in the burial environment by chemical and microbial agents are discussed. Determinants of the rate and extent of diagenetic alteration are considered. Prime among these is the availability of water, as this provides a medium for chemical reactions and is vital for supporting microbial metabolism. Other important factors are the pH of the soil water and the presence or otherwise of dissolved ionic species. The chapter concludes with a consideration of possible future directions for research.
