Abstract

This 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.

苏必利尔湖盆地原生铜矿床的铅同位素分析

本文是一项利用铅同位素分析来确定苏必利尔湖盆地原生铜来源的试验性研究。从苏必利尔湖盆地的原生铜矿床中采集了 40 个铅同位素样本，并在印第安纳大学的金属同位素实验室通过 MC-ICP-MS 进行了分析。分析结果表明，苏必利尔湖盆地内原生铜源的铅同位素特征之间存在明显的重叠。因此，不建议将铅同位素分析作为寻找苏必利尔湖盆地内原生铜来源的替代方法。

期刊介绍： Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
