BS>Correlative ratios of rare earth elements were established and systematics of composition and content of rare eanth elements in rocks of the Earth's crust were carried out. Maximum variations of rare earth elements are observed in alkaline rocks and granites. In the average massifs formed by alkaline rocks and granitoids are characterized by a strong prevalence of the ceric groups in comparison with ultrabasic and basic rocks. All rocks of the Earth's crust (including sedimentary and metamorphic) are distinguished by a higher content of rare earth elements being relatively enriched in the ceric group) in comparison with the silicate phase of chondrites, assumed to be analogous to the matter of the mantle. The latter is probably connected with dissemination chiefly of the yttric group of rare-earth elements in the deep- seated differentiates of the mantle (dunites) owing to the isomorphic entering of the rare-earth elements into Fe-Mg-silicates.
