Copper isotope ratios in Cis-Urals copper sandstones and products of their processing as a tool for uncovering the Bronze Age smelting activities

Copper isotope ratios are determined by MC-ICP-MS in a number of Cis-Urals copper sandstones and products of their processing. Malachite crusts are characterized by positive δ65Cu (+1.33‰÷+1.96‰) whereas the sludge with flux additives and experimental glassy slag have the lowest negative δ65Cu value...

Zusammenfassung:Copper isotope ratios are determined by MC-ICP-MS in a number of Cis-Urals copper sandstones and products of their processing. Malachite crusts are characterized by positive δ65Cu (+1.33‰÷+1.96‰) whereas the sludge with flux additives and experimental glassy slag have the lowest negative δ65Cu values (-4.87‰÷-4.32‰). δ65Cu = −0.54‰ is found for copper ingot obtained during the experimental smelting. Copper matte and sludge have negative δ65Cu values ranging from -2.33 to -2.61‰.
