Сhromespinelides with zinc-bearing epigene rims from Devonian conglobreccia horizons of Ichet'yu placer-like occurrence (Middle Timan)
Study results of accessory zinc-bearing chromespinelides from Middle Devonian psephites of Pizhemskaya suite (D <sub>2</sub>pg) of Ichet'yu placer-like occurrence (Middle Timan) are represented. According to electron microprobe analysis the most of chromespinelides have high-alumina contents and are classified as chrompicotites and subferrichrompicotites. Epigenetic metasomatic zincification of chromespinelides, associated phosphorus-bearing rare earth's accessory minerals (monazite, xenotime, florencite), phosphatic rims and inclusions in rare-metal accessory minerals (ilmenorutile, columbite, zircon) are considered as possible paragenetic mineral association, that all combined are related with large-scale regional metallogenic event, with Timan's Precambrian formation of rare and rare earth metals.
