A dome-like massif of 1.5x3 km this intrusion is bisected by a north-south-trending wrench fault with a horizontal displacement of a kilometre. It consists principally of peralkaline, often porphyritic, syenites which are cut by both north-northwesterly and northeasterly-striking swarms of peralkaline trachyte and porphyritic syenite dykes.
