This study aims at developing a reliable method for probing heat-induced diagenesis in human bones, by INS spectroscopy. The results thus gathered, coupled to Raman and FTIR data, will lead to an improved understanding of the changes undergone by bone upon burning events, allowing a reliable assessment of their effect on the metric dimensions of human skeletal remains. A quantitative relationship between spectroscopic parameters, macroscopic dimensional changes in burned bones and specific burning conditions (e.g. temperature and duration) is sought, which will be of the utmost relevance in forensic contexts (namely for the analysis of burned human remains from crime scenes), as well as in archaeological settings. This is a continuation proposal from a successful experiment the first INS analysis of human bones burned under controlled conditions (RB1520001).
