Titolo:  Dove approvvigionarsi? Disponibilità potenziali e sfruttamento neolitico dei depositi secondari di ossidiana lungo il versante sud-occidentale del Monte Arci (Sardegna, Italia)
Data di pubblicazione:  2012
Abstract:  The newly set and mapped secondary deposits of Monte Arci obsidians along the south-western flanks of the massif revealed an unexpected concentration and mixing of raw materials belonging to three (SA, SB2, SC) among the four discrete geo-chemical types actually exploited and put into circulation inside Neolithic exchange networks. It seemed us to be of great relevance to get a precise assessment of the spatial scale of distribution of these different obsidian groups, in order to propertly understand both the modes and strategies of prehistoric raw matter selection, procurement and circulation. Thus particular attention was given to a detailed mapping of obsidians distribution inside this complex mixing area, recording in the meanwhile the presence of blocks showing the minimal useful features to ensure the known Neolithic modes of reduction. It follows a better understanding of the raw material sourcing behaviours, as they are reflected in the different Neolithic systems of obsidian production.
