Abstract - Summary 
(short description):
New monazite mineralization was found in south-west part Sysert Block within the Ufimsk-Chelyabinsk structure, which is reputed as main rare-metal province of Urals. The mineralization is located within structural residual soil after leucogranites and gneisses and confined to exocontact of cross quartz vein. Monazite forms about 90 % by weight of heavy fraction, is represented as idiomorphic mainly prismatic crystals (n* 0.01-n* 0.1 mm) and morphologically looks like accessory monazite from leucogranites. Also are present ilmenite, rutile (ilmenorutile?), garnet, chromospinelides, zirkon, apatite, mixed iron oxides-hydroxides and single signs of xenotime, monocline pyroxene, titanite, tourmaline, barium sulfate, kyanite. Monazite differs in distribution of rare earth elements from accessory monazite from different granites. We suppose that new found monazite mineralization has hydrothermal origin and is bound up with leucogranites.
