Abstract
The obtained isotopic data allow the following conclusions. 1) The alkaline rocks and carbonatites of Edelweiss complex were formed at late-collisional stage of Middle Ordovician period. 2) The moderately depleted PREMA-type mantle served as a substance source for the formed comagmatic association. 3) Evolution of derivative melts was complicated by crust contamination, which effects were manifested as enhanced isotope ratios of Sr, O and C in rocks and minerals.
