Summary:Of the large number of Neolithic stone axes made of greenstone, some 392 (referred to as Group 1 axes) are believed to have been manufactured in west Cornwall around the Mount's Bay area. To aid the location of the greenstone that provided the materials for the axes, geochemical fingerprinting of the axes and greenstone outcrops was undertaken in the Mount's Bay area to both discriminate the greenstone localities and provide a basis for matching Group 1 axes. Non-destructive analysis of the axes was determined by a portable XRF Spectrometer unit that gave comparable results for selected greenstone samples to standard laboratory-based XRF techniques. Geochemical fingerprinting of the greenstone localities by portable XRF spectrometer provided a degree of discrimination between them, although preliminary data on the axes suggests that there is not a very strong correlation between axe composition and possible greenstone sites. Further work is required on other greenstone localities and axes as current data does not conclusively point to an origin in this area of west Cornwall.
