Abstract
AbstractThis paper is a pilot study using lead isotope analysis to source native copper in the Lake Superior Basin. Forty 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. The result of this analysis demonstrates that there is a significant overlap between Pb signatures of native copper sources within the Lake Superior Basin. As a result, lead isotope analysis is not recommended as an alternative for sourcing native copper within the Lake Superior Basin.
