Lead Isotopes

The use of lead isotopes in archaeology, initially as a technique to identify the source of the metal (primarily silver and copper) used for artifacts, but lately on a wider range of material and even human dental enamel, has gone through a typical cycle of enthusiastic adoption followed by a slower reevaluation of the best ways in which to deploy the technique.

Andean Ores, Bronze Artifacts, and Lead Isotopes

Lead isotope ratios have been used for many years to identify the sources of metal ores used in the production of artifacts with provenience in the eastern Mediterranean region (e.g., Yener et al. 1991; Sayre et al. 1992; Stos-Gale et al. 1995).In order to characterize the isotopic composition and variability of each ore source as completely as possible, these studies have …

This type of study is possible because the lead isotopic signature of an ore is not modified by metallurgical processes (Cui and Wu, 2011; Pernicka, 2014). Thus, it is possible to assume that the object was produced from minerals from a specific deposit when the signatures of a deposit and an artifact are comparable.
