Rare metal granitoids (Kulemshor, Subpolar Urals)

Granitoids of southern part of the Torgovsko-Keftalyksky massif with the developed complex of uranium-thorium and rare-metal-rare-earth minerals are considered. Granitoids belong to the A-type granites of the Late Cambrian period and were formed during the post-collision time, they mark the beginning of the rift stage of the Urals development. Mineralization is connected with sodium alkaline metasomatism shown in zones of cataclasis and mylonitization of granitoids.
