Ore specialization of carbonatite complexes at the Urais and Timan

Abstract

The ore specialization of carbonatite complexes of Urals-Timan region has been established: niobium and rare earth-niobium - for the Urals’ carbonatite complexes, the rare-earth - for carbonatites of Timan. The carbonatites of Il'menо-Vishnevogorsky miaskite-carbonatite complex (Urals) are a type of industrial niobium deposits (pyrochlore type of ores). The carbonatites of Baiksky ultrabasic complex (The Urals) are rare earth-niobium type deposits (monazite-aeschynite-columbite-pyrochlore type of ores). The carbonatites of Chetlassky complex (Middle Timan) are cerium type deposits of bastnesite carbonatites (with monazite-bastnesite type of ores). The picrite-lamprophire series of Chetlassky complex have diamond prospects. The ore specialization of the Urals and Timan carbonatite complexes are determined by their formational affiliation.
