From the perspective of the source. Neolithic production and exchange of Monte Arci obsidians (Central-western Sardinia)

The paper deals with the modes of Neolithic obsidian exploitation on the Sardinian source of Monte Arci, according to an integrated typo-technological/provenance approach. It focuses on the main changes in raw material selection and distribution criteria. Whilst from Early to Middle Neolithic they seem to have been influenced by technological and cultural factors, in Late Neolithic a dramatic shift in production behaviour is recorded. Then increased production rates are reflected in the appearance of a true structured exchange network which exerts bidirectional cultural and technological influences in the Northern Tyrrhenian region.
