Usakos is a town on the banks of river Khan, 140 kilometres north-east of Swakopmund in the Erongo Region of Namibia. It is located on the B2 (Trans-Kalahari Highway), the main road between the Walvis Bay and Johannesburg.
Surrounded by mountains, Usakos is quite picturesque. Certain spots around the town show the longest uninterrupted horizon in the world. It is the closest town to the Spitzkoppe, often referred to as the "Matterhorn of Namibia".
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 frequently 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.
