This 15 km2 body is intruded into Cambrian and Ordovician sediments and tuffs. It comprises biotite, riebeckite-biotite, aegirine-biotite and muscovite-riebeckite syenites that grade gradually into each other. Pegmatites are also typical for the massif. Dykes are not well developed in the intrusion but there are some early aplitic syenite and bostonite dykes while a second stage is represented by dykes of microdiorite and porphyry.
