This intrusion extends over 0.02 km2 only and cuts lower Palaeozoic diorites. Earlier rocks are coarse-grained peralkaline riebeckite syenite and younger ones fine-grained aegirine-riebeckite granite. Metasomatic quartz-microcline-albite rocks replace the peralkaline syenites and granites and are enriched in rare minerals including pyrochlore, columbite and lavenite.
