SW Gondwana resulted from complex interplay between continental amalgamation and
dispersal between ~ 650 and 490 Ma. The main cratons involved were Laurentia, Amazonia–
MARA (Proterozoic Maz–Arequipa–Rio Apa, Casquet et al., 2012), Kalahari, Rio de la Plata
(RPC), Congo and East Antarctica (Mawson block). Several collisional orogenic belts resulted,
notably the East Africa–Antarctica, Brasiliano–Panafrican, Pampean–Saldania, and Ross–
Delamerian orogens
