摘要：

The oxygen and carbon isotopic composition of different carbonates, silicates and oxides (magnetite, pyrochlore) from multistage carbonatites and certain silicate rocks of Gornoozero ultrabasic-alkaline carbonatitic rock suit was studied. Complicated character of isotopic compositional variations within the carbonatitic formation is demonstrated in respect of temperature decrease from early up to late stages of mineral formation. Generatical coherence of mineral assemblages forming in broad temperature range of carbonatite formation is demonstrated.
