Abstract

This work represents the first archaeometric study carried out on white marble artefacts coming from several areas of the archaeological site of S. Omobono, located in a central area of Rome (Italy). The study was performed on a total of nineteen marble items, sampled from several areas of the site, by combining different laboratory techniques – including optical microscopy (OM), X-ray powder diffraction (XRPD), Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Isotope Ratio Mass Spectrometry (IRMS) of C and O – with the aim to characterise them and to determine their provenance. The minero-petrographic features observed, together with the C and O stable isotopes ratios recorded, the evaluation of the Sr and Mn contents, and the XRD refinement of the calcite unit-cell parameters, allowed us to prove that the marbles used in the S. Omobono site mainly come from the Apuan Alps basin (Carrara) and, in few cases, from continental (Mt. Penteli) and insular (Paros-Lakkoi or Thasos-Aliki district) Greek quarries.
