  • 摘要:This paper presents the results of the geochemical characterisation of complete obsidian assemblages dating to the Early Aceramic Neolithic (8200–6900 Cal BC) and located in Cyprus, eastern Mediterranean. Obsidian artefacts have over the years been recovered from a number of Early Holocene archaeological sites on the island of Cyprus. As there are no obsidian sources on Cyprus, the presence of obsidian island-wide indicates long-distance sea transport/distribution, central Anatolia usually considered as the main supplying region. Portable XRF technology (X-ray Fluorescence Spectrometry) was applied to determine numbers of obsidian sources represented in complete archaeological assemblages and address research questions concerning the social landscape Cyprus was part of during the Early Holocene, a time of significant change in the broader eastern Mediterranean region.
