This massif is considered to be the surface manifestation of a large batholith - the so-called Azov Sea coastal batholith, which represents a deeply eroded syenite-granosyenite analogue of the anorthosite-rapakivi granite plutons (Karamsin, 1979). The batholith has been traced for 100 km in an east-west direction and for 55 km north-south, the total outcrop being 1500 km2. Alkali pyroxenes and amphiboles are found in some rocks. Veins of carbonate and fluorite are developed in the syenites and associated with faulting.
