This study aims at developing a reliable method for probing diagenetic alterations in human bones upon burning events, by INS spectroscopy. The results will be coupled to Raman and FTIR data (obtained concomitantly), with a view to better understand heat-induced changes in bone, thus providing a way to estimate their effect on the metric dimensions of human skeletal remains. This is an innovative way of tackling human bone tissue, that will pave the way for the analysis of other types of remains (e.g. teeth), leading to an improved understanding of burning-induced diagenesis. Such a quantitative method for assessing dimensional changes in burned human bones will be of the utmost significance in both anthropological and archaeological contexts, namely for the analysis of burned human remains from forensic scenes (e.g. victim identification) or archaelogical settings.
