Kalahari Craton Archaean-Palaeoproterozoic core of the craton is called the Proto-Kalahari Craton. This core plus accreted Mesoproterozoic crust and dispersed non-African fragments compose the Kalahari Craton. Before the Pan-African Orogeny, the Kalahari Craton was much larger than it is today, but its sutures and therefore its extent are difficult to locate due to later overprinting. The Kaapvaal Craton, Zimbabwe Craton, and Limpopo Belt are made of Archaean terranes and contain crust at least 3.2 and are underlain by a thick () layer of buoyant mantle that is producing garnets and diamonds. During the Palaeoproterozoic the northwest margin of the Archaean core grew
