Tracing the Source of Native Copper Mineral Specimens with Copper Isotope Values

摘要

A common problem in many collections is one of mislabeled or unlabeled Specimens. The practice of correcting errors and restoring lost species and locality and historical data is known as the reassociation of the specimens with their provenance. The Section of Minerals at Carn-egie Museum of Natural Histrory (CMNH) in Pittsburgh, Pennsylvania, has been actively conducting reassociation research on the museum's mineral, gemstone, and jewelry collections for more than two decades with some notable results.
