Yttrium-bearing zircons from psephites of Ichet’yu placer-like occurrence

Study results of epigenetically modified yttrium-bearing zircons from Devonian conglobreccia horizons of Pizhemskaya suite (D 2 pg ) of Ichet’yu placer-like occurrence (Middle Timan) are represented. It is supposed that products of epigenetic modifications of yttrium-bearing zircons and associated phosphorus-bearing rare earth accessory minerals (xenotime, monazite, florencite) have paragenetic relation with the same Timanian metallogenic formation, developed as a result of hydrothermalmetasomatic alterations of regional Precambrian (metamorphic) complexes of rocks.
