In plan this massif is lens-shaped with an area of 2.3x0.4 km. It intrudes middle Cambrian terrigenous carbonate deposits and is formed principally of alkaline syenites, but small bodies of ijolite and pyroxenite have been preserved amongst the syenites. The rocks of the intrusion have been extensively replaced by carbonate. Carbonatites are present and are dolomitic and ankeritic with rare-earth minerals abundant.
