Applications of Sr Isotopes in Archaeology

The inclusion of radiogenic strontium isotope (⁸⁷Sr/⁸⁶Sr) analysis in archaeological and bioarchaeological research has resulted in the creation of new data by which to evaluate models of migration, culture change, colonization, trade, and exchange. Overwhelmingly, archaeologists have used radiogenic strontium isotope signatures in human enamel and bone apatite to reconstruct ancient mobility patterns and to distinguish between individuals of local and non-local origins at archaeological sites. The method also has been employed to establish the provenience of artifacts, ancient building materials, and foodstuffs as well as to track the origins and migratory patterns of prehistoric animals. The present chapter provides an introduction to the fundamental principles, approaches, applications, and future directions of radiogenic strontium isotope analysis in archaeology.
