Fenite is a rare variety of metasomatite, a metamorphic rock formed solely by chemical alteration of previously existing rocks. As a result of a microprobe analysis of thin sections, at least three intrusion phases have been identified. Gravity data were used to create 3D models of the deep structure of these alkaline complexes down to the upper crustal level. Samples from the ultrabasic-alkaline and nepheline-syenite complexes Khibina, Lovozero, Afrikanda, Turiy Mys, Ozernaya Varaka, Sokli and Iivaara all yield ages in the very narrow range from 361.7 to 377.3 Ma, i.e. In the Kola Peninsula of Russia two giant nepheline syenite bodies exists making up the Lovozero Massif and the Khibiny Mountains.

The Kola Peninsula is one of the outstanding areas in the World for the concentration and economic importance of alkaline rocks. Igneous rocks of the Devonian Kola Alkaline Carbonatite Province (KACP) in NW Russia and eastern Finland can be classified into four groups: (a) primitive mantle-derived silica-undersaturated silicate magmas; (b) evolved alkaline and nepheline syenites; (c) cumulate rocks; (d) carbonatites and phoscorites, some of which may also be cumulates. Performed microscopic analyses that demonstrated their structure and optical features (dimming, interference colors, relief). Geology and geochronology of the Skjoldungen alkaline province . Ingrid, H. K . The Keivy alkaline province, Kola Peninsula, consists of six peralkaline granite bodies, alkaline syenogranite dikes, and two nepheline syenite intrusions emplaced between the tonalite-trondhjemite-granodiorite basement and the supracrustal Keivy terrane.
