Abstract
A set of 50 lead artifacts, out of which 29 were glandes plumbeae, found at archaeological sites located in the Cinca River basin (Huesca, Spain) were analyzed by MC-ICP-MS to determine lead isotope ratios. A comparison with lead ore deposits exploited by the Romans in the Iberian Peninsula allowed to differentiate two main groups of samples: those manufactured with Pb from nearby Pyrenean or Iberian Range ores (30%), and those from mining areas of Cartagena-Mazarrón in southeastern Spain or S'Argentera in the island of Ibiza (70%). This finding supports the existence of lead-ore extraction in the Central Pyrenees in the Roman period and enhances our understanding of metal supply networks in the region and army provisioning during the Sertorian war.
