Geochemical Sourcing of New Zealand Obsidians by Portable X-Ray Fluorescence from 2011 to 2018 (ppm/tech)

This dataset includes 4,582 obsidian artefacts matched to their natural geological source from 45 archaeological sites in New Zealand (Aotearoa). It is a compilation of a number of independent projects conducted in the laboratories of the University of Auckland and University of Otago from 2011 to 2018. It combines previously published studies, an MA thesis, a BA(Hons) dissertation, a site report, and other previously unpublished primary data. The dataset has high reuse potential for future non-destructive studies of artefacts and social network analyses.
