The casts of Pompeii bear witness to the people who died during the Vesuvius 79 AD eruption. However, studies on the cause of death of these victims have not been conclusive. A previous important step is the understanding of the post-depositional processes and the impact of the plaster in bones, two issues that have not been previously evaluated. Here we report on the anthropological and the first chemical data obtained from the study of six casts from Porta Nola area and one from Terme Suburbane. A non-invasive chemical analysis by portable X-ray fluorescence was employed for the first time on these casts of Pompeii to determine the elemental composition of the bones and the plaster. Elemental profiles were determined providing important data that cross-referenced with anthropological and stratigraphic results, are clearly helpful in the reconstruction of the perimortem and post-mortem events concerning the history of these individuals. The comparative analyses carried out on the bone casts and other collections from burned bones of the necropolis of Porta Nola in Pompeii and Rome Sepolcreto Ostiense, and buried bones from Valencia (Spain), reveal the extent of high temperature alteration and post-depositional plaster contamination. These factors make bioarchaeological analyses difficult but still allow us to support asphyxia as the likely cause of death. [ABSTRACT FROM AUTHOR]

The origin of iron‐oxide materials found at Paleolithic and Neolithic sites in the Spanish Mediterranean region is a pivotal issue that has not yet been explored. The aim of this study is to investigate the exploitation of local ochre sources during the different archaeological phases identified at the site of Coves de Santa Maira (Valencian Region, Eastern Spain). A sampling strategy and a methodological approach were developed. Lumps of ochre and raw materials were sampled from the archaeological site and its surroundings. The archaeological materials studied are from the occupational phases dated to between 15 and 6 ka cal BP, whereas the raw materials sampled from the surroundings of the cave are red fine‐grained and earthy‐grained sedimentary materials and Late Triassic (Keuper) clays. Morphological, mineralogical, and chemical analyses of the samples were carried out, and quantitative data on ochre fragments and processing tools recovered at the site were also included. Finally, Fe‐normalized and log10 transformed data and multivariate statistical analysis, using major, trace, and rare earth elements as variables, were applied to compare the mineralogical and chemical profiles of the archaeological materials with those from geological sources. The results obtained have provided interesting data about iron‐based mineral exploitation during Prehistory in the studied region. [ABSTRACT FROM AUTHOR]

In this work, five unique Iberian Iron Age handles have been studied. The use of portable X-ray fluorescence (pXRF) and Fourier transform near–infrared (FT-NIR) spectroscopy no-destructive techniques has allowed us to identify two raw materials (amber and tin) used to decorate the ivory handles. Due to the finesse of their inlaid decoration and the value and exoticism of the material employed for their manufacture, these ivory objects are really exceptional Iberian archaeology findings. Interestingly, it has been possible to determine that tin was used as an adherent material to fix the inlaid small pieces of amber in the handles. The obtained results allow the better understanding of the manufacturing processes, areas of production, and accessibility to exotic materials of valuable objects during the Iberian period.
