The studied intrusive massif is an ellipse elongated in the sublatitudinal direction. Only the eastern part, 2.2x4 km in size, is exposed on the earth surface. Under the sediments, the intrusion was traced by boreholes and aeromagnetic survey. The intrusion is a sheetlike body of a fractured nature, inclined to the southwest. A zone of marmorized limestones, as well as tremolite and wolastonite hornfelses, formed at the contact with the intrusion. Among the intrusive rocks that make up the massif, three successive igneous phases are distinguished. The first phase is represented by pyroxenites, biotite pyroxenites, alaskites, hornblendites, pyroxene-hornblende shonkinites and pseudoleucite facies, in which mesocratic and melanocratic syenites are distinguished. The rocks of the second phase are pyroxene-biotite and hornblend-biotite-pyroxene shonkinites, monzonites, syenites, which have gradual transitions. The rocks of the third intrusive phase are represented by biotite-pyroxene-hornblend syenites. A characteristic feature of syenites is the abundance of xenoliths of rocks of the first and second phases and marbles. The main rock-forming minerals of these rocks are orthoclase, hornblend, diopside-augite, minor ones: biotite, acidic or intermediate plagioclase, nepheline. The rocks of the intrusion are enriched in zinc, yttrium, copper, tin, molybdenum, vanadium, and lead. In addition, they contain increased amounts of cobalt and silver. Intrusions have been studied and their prospects for rare metals and rare earth elements have been evaluated.
