The contents of Na, Al, Si, K, Ca and Fe of 99 obsidians from the western Mediterranean islands of Lipari, Palmarola, Pantelleria and Sardinia were determined with the energy-dispersive spectrometer of a scanning electron microscope (SEM-EDS). The Na and in a lesser way other elements contents characterize any obsidian source-island. In Sardinia (80 samples), the four Monte Arci obsidian geochemical types can be discriminated from binary diagrams of element contents or by a discriminant analysis based on the six elements measured. It is concluded that SEM-EDS offers a new option for Neolithic obsidian provenance studies in this region. To cite this article: F.-X. Le Bourdonnec et al., C. R. Geoscience 338 (2006).

Les teneurs en Na, Al, Si, K, Ca, Fe de 99 obsidiennes des îles de Lipari, Palmarola, Pantelleria et Sardaigne (Méditerranée occidentale) ont été déterminées en microscopie électronique à balayage par spectrométrie de dispersion dʼénergie. Les teneurs en Na et, dans une moindre mesure, celles des autres éléments caractérisent les îles-sources des obsidiennes. En Sardaigne (80 échantillons), les quatre types géochimiques du Monte Arci peuvent être distingués par des diagrammes binaires de teneurs élémentaires ou par analyse discriminante à partir des six éléments analysés. Cette technique offre donc une nouvelle option dans lʼétude régionale de la provenance des obsidiennes néolithiques. Pour citer cet article : F.-X. Le Bourdonnec et al., C. R. Geoscience 338 (2006).
