Abstract
Geochemical
studies of lithic artefacts in archaeology have been based on find a relation
between the archaeological materials and the primary source present in nature
using their chemical profile. Provenance information results useful to rebuilt
settlements patterns, investigate stone tool technologies, exchange systems and
territoriality . The aim of this study was to
explore the capability of rare earth elements (REEs), analyzed by ICP-MS and
employing multivariate statistics, for the identification of diabase outcrops
employed for lithic artefacts (axes) manufacture found in some
Valencian Prehistoric sites. These preliminary results
show that REEs analysis can help to assess the provenance of lithic raw
materials according to their elemental profile at regional level.
Keywords: Rare Earth Elements (REEs);
ICP-MS; multivariate statistics, lithic
artefacts, diabase outcrops.
