    The Santa Vitória Chalcolithic site (southern Portugal) prompts several questions related to the provenance and production technology of artefacts. Archaeological ceramics from two sections of Ditch 1 of the Santa Vitória site were studied by neutron activation analysis and X-ray diffraction for the first time, with the main goal of contributing to the contextualization of the artefacts and better understanding their production processes/technologies and the provenance of raw materials. The results point to a local production of ceramics, since their mineral phases reflect the geological contexts around the archaeological site. The mineralogical assemblage indicates a firing temperature below 850 ◦C. Iron is the better discriminator of ceramics from both sections, which could be related to the addition of different proportions of temper grains during the ceramics’ production. Although trace elements do not serve as discriminating geochemical indicators for the analyzed samples, they do imply a slightly higher heterogeneity in the composition of the ceramic paste from section 2. The negative Eu anomaly found in two samples is in accordance with the lower contents of Na2O, related to plagioclase weathering. Detailed studies on ceramics and potential raw materials are foreseen to assist in discussing the role of this Chalcolithic archaeological site at a regional level.

  • Roman-indigenous interaction in the Salas River valley (Northwest Iberia): the Roman camp of Alto da Raia and its archaeological landscape.
    Publication . Fonte, João; Tereso, João Pedro; Vaz, Filipe Costa; Rodrigues, Ana Luísa; Dias, Maria Isabel; Marques, Rosa; Russo, Dulce; Monteiro, Patrícia; Rodrigues, Mariana Costa; Pereiro, Tiago; Carvalho, José; Raimundo, Francisco; Cardoso, Vanessa; Jorge, Carlos; García Sánchez, Jesús; Gago, Manuel; Gonçalves, José Alberto; Meunier, Emmanuelle; Oliveira, Nuno; Oltean, Ioana
    This paper discusses the archaeological research and historical contextualisation of the Alto da Raia enclosure located on the border between northern Portugal and Galicia, identified as a possible Roman camp, following an interdisciplinary and multi-proxy approach. This included archaeological excavation, remote sensing and geophysical survey, as well as sample collection for archaeobotanical and geochemical studies by means of chemical and mineralogical analyses and absolute dating using radiocarbon and luminescence protocols. The results seem to indicate that this site was a Roman camp probably built and occupied between the 1st century BC and the 1st century AD, when major changes occurred in Northwest Iberia driven by the expansion of the Roman State. The camp overlaps with previous prehistoric occupations possibly dating back to the Bronze Age and Iron Age.
