Chapter 5.6 Syn- to Post-Orogenic Magmatism
Abstract Syn- to post-tectonic intrusive rocks occur in the Kaoko Belt, but only west of the Purros Lineament and in the Southern Kaoko Zone. In the Damara Belt, granites occur almost exclusively in the Central Zone with some extending into the Northern Zone. The Donkerhuk Granite forms a major batholith along the northern edge of the Southern Zone and a few small plugs of alkali-feldspar granite intruded the eastern Southern Marginal Zone. Syn-tectonic granites are absent in the Gariep Belt, where only post-tectonic plutonic rocks occur along the Kuboos-Bremen line. In the Saldania Belt, however, a whole range from syn- to post-tectonic intrusive and extrusive rocks exists.
