The Central Zone is regarded as having docked with the Kaapvaal Craton during c. Ga (McCourt et aI., ; McCourt and Armstrong, ) or c. Ga (Kroner et aI., ) transpressional collision. The structural data exhibited by .

Bumby and van der Merwe () and Bordy () indicate the possible influence of the Limpopo Mobile Belt as well as the failed East African Rift System on the formation of . Current and future research aims to examine the tectonic evolution of the Proterozoic Namaqua Sector of the Namaqua-Natal Province of southern Africa, particularly along its eastern margin at its contact with the Archean Kaapvaal Craton and to further understand the tectonic evolution of the region and its place in the Mesoproterozoic.

      ). The Kaapvaal craton is bounded on the south and east by the Namaqua–Natal Proterozoic mobile belt (ca. – Ga) and on the west by the Kheis overthrust belt (ca. Ga) (De Wit et al., ). The regional seismic array extends across the Phanerozoic the Cape Fold belt at the southernmost extent of the continent. models also propose NNMB up to the northern edge of the Cape Fold Belt Front (e.g. Cornell et al. ; de Beer and Meyer, ;) but the NVR seismic image presents evidence to suggest the NNMB continues below the CFB tectonic front and possibly farther south to the continental margin.

The Kaaien Terrane forms a tectonic transition between the Kaapvaal Craton, Rehoboth Province, Kheis belt and the Archeachap Terrane of the Namaqua Sector and forms part of an NW-vergent foreland.

The Zager licence is situated within the Neo-Proterozoic Nakfa terrane of the Arabian Nubian Shield, a highly prospective mobile belt of metasedimentary and metavolcanic rocks which stretches across northern and western Ethiopia, Eritrea, Sudan, Egypt and across the western Gulf. Gneissic rocks in the Augrabies Falls National Park are part of the Proterozoic Namaqua-Natal mobile belt.

Finding neotectonic evidence in old terranes is always not an easy task. In South Africa, the mid-Miocene is believed to be the beginning of neotectonics.
