Lunnyi is composed of fluorite-bearing carbonatites at the borders of which are developed leucocratic alkaline metasomatic rocks. The carbonatite forms small bodies, the majority only 10s of metres in diameter, but the largest of which, located near the Lunnyi spring, is 250x120 m. The carbonatites are medium-grained, massive rocks, containing 60-80% carbonates which are mainly calcite, with rare ankerite, dolomite and siderite. Other minerals present include baryte, fluorite, hematite, flourite and fluorcarbonates of the rare earths. Albite, phlogopite, apatite and magnetite are found in some varieties.
