However, little is understood about the acquisition and exchange of turquoise by Native American societies because the geological sources of most turquoise artifacts from archaeological sites in the southwestern U.S. and Mexico are not known. We evaluate the potential for Pb and Sr isotopic ratios to indicate the geological provenance of turquoise artifacts recovered from these regions. Pb and Sr isotopic measurements were made on 137 geological samples of turquoise from 19 mining districts across the southwestern United States and northern Mexico. These data reveal that isotopic signatures of turquoise deposits vary geographically according to regional and local differences in the geologic settings of turquoise mineralization. As an archaeological case study, we also report Pb and Sr isotopic data on 10 turquoise artifacts recovered from three late pre-Hispanic (ca. A.D. 1250–1400) ancestral Zuni sites located in the El Morro Valley of western New Mexico. These have isotopic signatures uniquely consistent with the turquoise deposits of the Cerrillos Hills, a location identified in Zuni traditional history as an ancient source of turquoise. These data thus establish Pb and Sr isotopic measurements as powerful tools for determining the sources of turquoise artifacts and provide a new framework for evaluating the role of turquoise in pre-Hispanic exchange networks across North America.
