А body of metapsevdotahylite with Th-U-Y-REE mineralization including fergusonite-(Y) (up to 7 wt. % UO2) and «thorogummite» (up to 29 wt. % UO2) was found in the central alkaline band of the Ilmeny-Vishnevogorsky polymetamorphic complex. The study of minerals with rare and rare earth elements, their assemblages, and the genesis of host rocks signifcantly expand the potential of prediction and evaluation of the distribution of these minerals in metamorphic complexes.
