The results of studying of a rare-earth mineralization in ore-magmatic systems of the Russian Far East are considered. The assemblage of REE minerals in pre-ore monzonitic rocks, ore-bearing lithium-fluoric granites and ongonites, as well as in metasomatites accompanying them is given. The conclusion about a two-stage evolution of rare-earth complexes composition is drawn and its main tendencies are determined. The genetic relationship of rare-metal granitoids and metasomatites of the Far East ongonitic areas is established. The prospectivity of a rare-earth mineralization in metasomatites of a zwitter-turmalinitic formation of the region are noted.
