Th-U-Pb-age of monazite vein series of Chetlassky complex (Novobobrovskoe ore field, Middle Timan)
The age for monazite (552 ± 31 Ma, Th-U-Pb, CHIME) from the rocks vein series of Novobobrovskoe ore field (Middle Timan) has been determined. These data confirm that the rock vein series, bearing complex rare-metal-rare earth mineralization (columbite, monazite, xenotime, rare earth carbonates), are close to the time of formation of Vendian magmatic rocks (picrites and carbonatites of the Chetlassky complex (Middle Timan)), which are genetically related.
