In this area to the south of the Tomtor complex (No 3) and, like Tomtor, located on the Udzhinsky rise, there are a number of small dykes, veins and stock-like bodies of alkaline ultrabasic rocks, nepheline syenites and carbonatites. The last are represented by calcite, dolomite and ankerite-siderite varieties.
