英文摘要: The composition and structure of experimentally heated modern bone and cremated bone fragments from various archaeological sites were analysed by Fourier Transform Infrared Spectroscopy (FTIR) in Attenuated Total Reflectance (ATR) mode before and after pre-treatment with acetic acid. The results confirm that time and temperature have an impact on the degree of calcination but also highlight that, once fully calcined, the final composition and structure of bone are influenced by temperature alone. A combination of several infrared indices makes it possible to discriminate between bones cremated under different conditions. The study of archaeological samples revealed that their carbonate composition is quite different to modern calcined bone and that some samples, originating from high-carbonate geological contexts, have significantly higher carbonate concentration compared to modern specimens, even after pre-treatment. The results suggest that FTIR yields information on not just the structure of burned bone, but also potentially about the modes of burning, including cremation, and the depositional conditions. © 2014 Elsevier B.V.
