The history of the Central Namib includes the following: deposition, metamorphism and granitization of the Precambrian; planation of the Precambrian to form the Namib Unconformity Surface, an unweathered pediplain with a few inselbergs thought to be of Jurassic age; deposition of the Tsondab Sandstone, a terrestrial sandstone thought to be equivalent to the Kalahari System, and of Upper Cretaceous and Tertiary age; planation to form the Tsondab Planation Surface, a vast pediment crossed by east-west drainage; incision of the Tsondab and Kuiseb Rivers with formation of minor terraces: formation of the modern sand dunes.
