Abstract

Porosity measurements made on archaeological bones have revealed very close relationships between changes in the porosity, remaining protein content and mineral alterations. The results have important implications for models that attempt to quantify the rates and extent of chemical reaction between bone and its geochemical environment. We report here on a novel application of an established technique, mercury intrusion porosimetry, to investigate in more detail the pore size distribution of archaeological bones. Mercury intrusion porosimetry measures an 'intermediate ' range of bone porosity, 'mesoporosity', and produces data which permit the observation of significant structure characteristics in the porosity of modern, laboratory altered and diagenetically altered bones.
