Data on the concentrations of K, Ca, Ti, Fe, Cu, Zn, Ga, Rb, Sr and Zr obtained by PIXE and of B, F, Na, Mg, Al, Si and Cu
obtained by proton-induced prompt gamma-ray spectrometry were used to characterize archaeological artefacts and source materials
by multivariate analysis. The mathematical approaches employed were cluster analysis using nearest-neighbour data, multidimensional
scaling and correspondence analysis.
