“…This event is widespread over South Africa, Botswana, Zimbabwe, Namibia and Antarctica over an estimated paleo-surface of ca. 2.5 × 10 6 km 2 (Hanson et al, 2004;Becker et al, 2006;Hanson et al, 2006;Jourdan et al, 2009). The possibility that the Congo Craton has also shared this magmatic event at 1.1 Ga has been recently suggested by Ernst et al (2013).…”

“…3). It includes the Kgwebe Formation of Botswana and the Sinclair and Nauzerus groups of Namibia (Becker et al 2006 and references therein). The Sinclair Group includes four thick, conformable volcano-sedimentary cycles deposited in north-south elongated basins (Watters, 1974;Borg, 1988;Hoal, 1990;1993).…”

“…SHRIMP U-Pb zircon dating (Robb et al 1998) indicated two crust-forming events in the Namaqua Complex at 1,220-1,170 Ma (Kibarian) and 1,060-1,030 Ma (Namaqualand). The Namaqua Metamorphic Complex is interpreted as a deformed and metamorphosed sedimentary passive margin succession at the west of the Kalahari craton (Becker et al 2006;McCourt et al 2006;among others). Related to the Kibarian event, there was regional deformation with granulite facies metamorphism and intrusion of granitoids represented by the Nababeep and Modderfontein gneisses.…”

The Punta del Este Terrane (eastern Uruguay) lies in a complex Neoproterozoic (Brasiliano/Pan-African) orogenic zone considered to contain a suture between South American terranes to the west of Major GercinoSierra Ballena Suture Zone and eastern African affinities terranes. Zircon cores from Punta del Este Terrane basement orthogneisses have U-Pb ages of ca. 1,000 Ma, which indicate an lineage with the Namaqua Belt in Southwestern Africa. U-Pb zircon ages also provide the following information on the Punta del Este terrane: the orthogneisses containing the ca. 1,000 Ma inheritance formed at ca. 750 Ma; in contrast to the related terranes now in Africa, reworking of the Punta del Este Terrane during Brasiliano/Pan-African orogenesis was very intense, reaching granulite facies at ca. 640 Ma. The termination of the Brasiliano/Pan-African orogeny is marked by formation of acid volcanic and volcanoclastic rocks at ca. 570 Ma (Sierra de Aguirre Formation), formation of late sedimentary basins (San Carlos Formation) and then intrusion at ca. 535 Ma of post-tectonic granitoids (Santa Teresa and José Ignacio batholiths). The Punta del Este Terrane and unrelated western terranes represented by the Dom Feliciano Belt and the Río de La Plata Craton were in their present positions by ca. 535 Ma.
