Abstract

Copper isotope ratios differ between hypogene sulfidic, supergene sulfidic and oxidized ore sources. Traditional lead isotope signatures of ancient metals are specific to deposits, while Cu isotope signatures are specific to the types of ore minerals used for metal production in ancient times. Two methodological case studies are presented: First, the mining district of Faynan (Jordan) was investigated. Here, mainly oxidized copper ores occur in the deposits. The production of copper from Fayan’s ore sources is confirmed by the measurement of the Cu isotope signature of ingots from the Early Bronze Age metal workshop from Khirbat Hamra Ifdan. Based on our results illustrating differences in the Cu isotope composition between the ore mineralizations from Timna (Israel) and Faynan, it is now possible to determine these prehistoric mining districts from which copper artifacts originated by combining trace elements and Pb isotopes with Cu isotopes. The second case study presents data on Late Bronze Age copper production in Cyprus. Oxhide ingots from the shipwreck of Uluburun (Turkey) were tested for their lead isotope signatures and assigned to Cypriot deposits in the recent decades. The oxhide ingots from Uluburun show a Cu isotope signature which we also found for oxidized copper ores from Cyprus, while younger oxhide ingots as well as metallurgical slag from the Cypriot settlements Kition and Enkomi show a different signature which might be due to the use of sulfidic ore sources from a greater depth of deposits. We assert that there could be a chronological shift from oxidized to sulfidic ore sources for the copper production in Cyprus, requiring different technologies. Therefore, Cu isotopes can be used as a proxy to reconstruct mining and induced smelting activities in ancient times.

This study was funded by the Leibniz-Kompetenzzentrum Archäometrie at the German Mining Museum (Deutsches Bergbau-Museum). In previous studies, Thomas E. Levy and Cemal Pulak provided the opportunity to take samples from Bronze Age ingots. We are grateful for the support of Vasiliki Kassianidou, George Hadjigeorghiou, Constantinos Xydas, and Lazaros Georgios during a stay in Cyprus for sampling ore specimens in the field and additional ones from the survey collection of Ulrich Zwicker. We thank Wolfgang Steger and Michael Bode who supported the sample preparation in the clean lab in Bochum. Sincere thanks are given to the anonymous reviewers for their valuable comments.
