The Canadian Palaipaphos Survey Project in the Paphos district of south‐western Cyprus investigated extensive areas of the Esouzas, Xero, and Dhiarizos River valleys, locating hundreds of archaeological sites spanning the nine millennia from the aceramic Neolithic period to the recent era (Ruppet al.s1984 and 1986). Antigorite artefacts were recovered from Neolithic, Chalcolithic and Bronze Age settlements. A number of geological sources have been proposed for the material from which these artefacts were manufactured. The results of neutron activation analyses of archaeological and geological specimens suggest that the Troodos ophiolite/Kouris River secondary deposits were the primary source of antigorite for the prehistoric populations of the study area. Extreme care must be taken when analysing antigorite samples to avoid material with grey‐black magnetite‐rich inclusions. since these have radically different trace element chemistries from the pure antig
