The obtained isotopic data suggest the following conclusions: alkaline rocks and carbonatites of the Edel'veis Complex formed at the late collisional stage in the Middle Ordovician; the comagmatic association was derived from moderately depleted PREMA-type mantle; and evolution of derivative melts was complicated by crustal contamination, which was responsible for increase in Sr, O, and C isotopic ratios in rocks and minerals.
