Abstract. The study of contact aureole rocks of the alkaline-ultrabasic massif Ozernaya Varaka has been conducted. Typochemical features of the minerals of the selected paragenetic associations have been determined; they indicate that the change of polymetasomatic alteration stages was accompanied by a change in sources of material, the nature and scale of mass transfer, the physical-chemical conditions in the course of metasomatic processes. Despite the low prevalence of carbonatites within the massif Ozernaya Varaka the high importance of the carbonatite process in shaping the modern image of rocks of fenite aureole has been discovered. Results of the study indicate the possibility of formation of the significant amounts of albitized rocks on the regressive stage of the carbonatite process due to remobilization of Na, Al and Si from sinmagmatic alkali metasomatites.
