Mineralogy of granitic pegmatites of Mt. Soroch′ya near Zlatoust which ore included in the Upper Riphean metamorphic mica-garnet, staurolite-garnet, and wollastonite-sillimanite-garnet schists of the Kuvash Formation is examined. Zonal pegmatite veins 30-600 m long and 1-40 m thick are composed of (from margin to centre): 1) pegmatoic quartz-two-feldspar with muscovite and biotite; 2) graphic muscovite-quartz-two-feldspar; 3) blocky with large crystals of microcline, muscovite (up to 10 cm) and quartz in small-grained quartz-albite aggregate; and 4) quartz core zones. The composition of formerly known mica, tourmaline, zircon, rutile and first time discovered xenotime-(Y), monazite-(Ce), Ta-bearing rutile (“strьverite”), and gold is ore described.
