Substantial intrusion of nepheline syenite 10 x 6 km, the most easterly two thirds of which is located in Mozambique and one third - in Malawi. It forms a mountain rising 800 m from the raised shore lines to the SE of Lake Chilwa. At the western end of the intrusion (within Malawi) the nepheline syenite is cut by Songwe vent of breccia and Songwe Hill REE Project (Songwe Hill carbonatite), Phalombe, Southern Region, Malawi.

The area has been shown to be a potential, but small source of bauxite.
