Copper Mines,Chromite Copper Ores and Slags of the Ishkinino Bronze Age Archaeological Microregion,The Southern Urals

The study addresses copper mines structure and composition of copper ores and slags at the Ishkinino archaeological microregion, Orenburg Province. Both ores and slags contain chromites derived from the host ultrabasite rock. Chromites were subdivided into three categories in terms of Cr2O3 content: 45–50%, 50–55%, and 55–61%. The proportions are similar to those observed in chromites of the malachite ores of the Ishkinino cobalt-copper-pyrite deposit. The reguli found in the slag contain copper sul?des and iron phosphides with a high content of nickel. Our results evidence the exploitation of local copper mines in the Late Bronze Age. Finds of chromite ores and slag at the archaeological sites of the Southern Urals are listed, and goals for future research are outlined.     

An Alakul funeral and ritual site in the Eastern Orenburg region

An unusual funeral and ritual site of the Alakul culture is described. It is situated in the northern periphery of a Late Bronze Age mining and metallurgical center in the Ural–Mugodzhary region, and is associated with the Ishkinovka group of ancient copper mines, which began to be exploited in the Early Bronze Age. A stone statue and votive objects suggest that the kurgan was a sanctuary marking a tribal area and a ritual center of a population engaged in copper mining and copper metallurgy
