Abstract
The concentrations of five trace elements (Rb, Zr, Sr, Ti and Mn) and one major (Fe) element have been determined in groups of obsidian samples by wavelength dispersive X-ray fluorescence spectrometry. Two methods were used for different elements on the basis of different excitation conditions and sample preparation procedures. Synthetic standards with compositions similar to those of the igneous stone were prepared into which the analytes were incorporated in solution. The method was used to establish the provenance of a number of prehistoric obsidian artifacts. The results ascertained in these analyses are discussed in this paper.
