In the area around Karibib, Usakos and Cape Cross, an important pegmatite field is situated, measuring about 200 x 100 km. The pegmatites are of late Damaran age; many are well mineralised and important sources of Li, Cs, Be, Sn, Nb, Ta and Bi minerals, ceramic feldspar and quartz, and a few contain gem tourmalines. The majority may be considered as Li pegmatites, but there are also Be and Sn pegmatites. The nature of Li pegmatites is discussed in detail; they may be subdivided in amblygonite, spodumene, petalite and complex Li pegmatites. A number of minerals included in those pegmatites is also described.
