Usakos Pegmatites:
Internal zoning is well developed in most pegmatites and prominent quartz cores are seen in many deposits. It must be stressed, however, that the important tin pegmatites of the Uis swarm as well as some other economic pegmatites are poorly zoned to unzoned. Although quartz cores and core margins are often mineralised, economic minerals are also confined to other pegmatite zones at several localities. Many pegmatites carry an assortment of beryl, columbite-tantalite and/or other Ta-Nb oxides, lepidolite, amblygonite-montebrasite, cassiterite, petalite, gem tourmaline, pollucite, microlite, spodumene, bismuth minerals, and a variety of Li-Fe-Mn and Fe-Mn phosphates and their alteration products.
