Rare-earth and rare-metal mineralization in late granite of Syrostan massif (Southern Urals)

Abstract

The article provides a complete list of Syrostan massif minerals, which includes 47 mineral species. It is shown that the rare-metal and rare-earth mineralization is confined to the late vein facies - granite dykes and pegmatites. Characteristic morphology and composition of new minerals of the massif: fergusonite-(Y), euxenite-(Y), polycrase-(Y), broggerit, thorogummite, and minerals already known: samarskite-(Y), columbi-te-(Mn), ilmenite, ilmenorutile, zircon, cyrtolite, allanite-(Ce) are given. Previously, it was found that allanite and titanite make the largest contribution to the balance of REE in the rocks of the main phases of the massif. These studies let to distinguish the new specialization for the massif - Nb-Ta-Ti-Y-REE-Zr-Th-U, connected with the rare-earth-rare-metal minerals association of vein granites and pegmatites.
