Journal of the Royal Society of New Zealand abstractsNew Zealand and Oceanic obsidians: an archaeological perspective using neutron activation analysisFoss Leach*Neutron activation analysis was carried out on 203 obsidian samples from 32 known sources in New Zealand and the Pacific islands. Concentrations are presented for 23 elements, and the data are examined through various kinds of statistical treatment, including canonical variate and factor analyses, to reveal the underlying patterns of regularity and distinctiveness amongst the sources. The implications for sourcing archaeological artefacts are discussed.Keywords: Obsidian, neutron activation analysis, New Zealand, Pacific, archaeology, artefact sourcing.
