| Abstract: | The results of study of the Bobruisk ring structure (Republic of Belarus) containing ~80 rare rockforming and accessory minerals are reported. Among them are native (Fe, Cu, Sn, Zn, Pb, Ag, Mo, W, Al) and intermetallic (Fe, Cr, Ni, Mo, B, N, C, Si) compounds, natural alloys (Fe–Cr, Fe–Cr–Mo–W–B; brass (Cu–Zn–Pb); and bronze (Sn–Pb–Zn–Cu)). They are observed as segregations of various shapes and sizes, as well as their aggregates. The formation of mineralization is controlled by reduced mantle fluids enriched in H2, CH4, CO, Si, N, and O and stimulating accumulation of rare elements as native and intermetallic phases, alloys, rather than isomorphic impurities in minerals. |
