Lead Isotope Analysis of Native Copper Deposits in the Lake Superior Basin

This data set is from a pilot study using lead isotope analysis to source native copper in the Lake Superior Basin. Thirty-eight Pb isotope samples are sampled from native copper deposits across the Lake Superior Basin and analyzed via MC-ICP-MS at Indiana University’s Metal Isotope Lab. Funding was provided by the Indiana University Museum of Archaeology and Anthropology and Isle Royale National Park.
