We point to sulphosalt ores as the main source of metal for the Fi nal Neo lithic/Early Bronze Age cop per artefacts from south ern Po land. The in clu sions, rich in Ag, As, Sb and Sn, doc ument the type of ore, re gard less of the met al lur gi cal pro cess lead ing to de ple tion of As and Sb. The cop per metal should contain nei ther Sb nor As, hence both of these el e ments, if orig i nally pres ent in ore, can be pre served only in in clu sions. The con cen tra tions of Ag, Sb, As and Sn in the artefacts in ves ti gated, the pres ence of in clu sions, and their chem i cal com po si tion, are the key in di ca tors for the de ter mi na tion of the min er al og i cal com po si tion of the orig i nal ores. Given the high con cen trations of Sb, As and Ag in the Cu metal and min er al ogy of the in clu sions, the ore must have con tained vary ing pro por tions of Ag-bear ing tetrahedrite (Cu,Fe) 12 Sb 4 S 13 and ten nan tite (Cu,Fe) 12 As 4 S 13 .

Probing the provenance of archaeological glaze colorants: Polychrome faunal reliefs of the Ishtar Gate and the Processional Way of Babylon

et al. 2019

The polychrome glazes from the Processional Way and the Ishtar Gate of Babylon are among the best preserved from antiquity. Yet, little is known about the logistical choices involved in their production. Variations in isotope ratios can be useful for complementing an archaeological investigation of potential geological sources of raw materials. Consistent with archaeological evidence and ancient texts on trade in metals, Turkish ore deposits are thus tentatively proposed as possible sources of the metal oxide colorants used for the investigated polychrome glazes of three Neo-Babylonian faunal reliefs that are now part of the collection of the Ny Carlsberg Glyptotek, Copenhagen.

“…Manufactured, slag and other metallurgical by-products inherit the isotope signature of Cu ore concentrates (Šillerová et al, 2017). As Cu isotope compositions of minerals formed in high temperature (>250 °C) -such as chalcopyrite, CuFeS2 -are different from low temperature (<100°C) minerals -such as chalcocite, Cu2S-, Cu has become a promising tool to trace origins of archeological materials and archeometallurgical processes (Jansen et al, 2018;Klein et al, 2009). Since anthropogenic Cu may derive either from sulfides or oxide ore deposits, Cu isotope systematics can help discriminate the different anthropogenic and natural sources.…”

Toulon bay is severely impacted by metal contamination induced by past and recent naval activities. In this work, Cu, Zn and Pb isotope compositions and elemental concentrations of fifty-five surface sediments were determined in order to map the spatial distribution of anthropogenic and natural sources along this land-sea continuum. Two subsystems of Toulon Bay, the Small and Large bays, showed wellmarked patterns on metal contamination levels and isotope signatures for Cu and Pb. The Small bay had the highest metal concentrations, and displayed average Pb and Cu isotope compositions of 1.1664 ± 0.0043 (1s, expressed as 206Pb/207Pb ratios) and −0.17 ± 0.19‰ (1s, expressed as δ65CuNIST values), respectively. It contrasted with the Large bay, with moderate to pristine metal concentrations and average Pb and Cu isotope compositions of 1.1763 ± 0.0079 (1s) and +0.08 ± 0.23‰ (1s), respectively. Lead isotope systematics indicated a binary source mixing process involving industrial and natural sources, while Cu isotope systematics showed a ternary mixing process involving two distinct anthropogenic signatures, interpreted as associated to new diffuse anthropogenic sources and old warfare material. In contrast, Zn isotope compositions in the Small and Large bays were practically the same: +0.06 ± 0.05‰ and +0.06 ± 0.11‰ (1s, expressed δ66ZnJMC values), respectively, denoting an overlap between isotope signatures of natural and anthropogenic sources. This study presents the first detailed spatial distributions of Cu and Zn isotope compositions for an aquatic system, and demonstrates the feasibility to use Cu isotopes as tracers of anthropogenic sources in coastal environments. Highlights ► Cu isotope systematic show a mixing process of natural and anthropogenic sources. ► Low Cu contaminated sediments display δ 65 CuNIST values ranging from 0.0 to +0.2‰. ► Contaminated sediments by diffuse sources tend to negative δ 65 CuNIST values. ► Pb isotopes reveal mixing process involving industrial and natural sources. ► Zn isotope system does not allow identifying mixing source processes.
