Abstract:We present some preliminary results of Pb isotopes characterization of gold samples.The first aim of this work is to apply an archeometry technique, that is, geographical origin characterization of ancient artifacts in order to characterize gold provenance. Using Pb isotopes in gold samples in which that metal is found as a trace is possible using ICP MS techniques. In this work was also used laser ablation to extract material from the sample.Samples have been obtained from three brazilian geographically disti… Show more
