Breakup of a Paleoproterozoic Supercontinent

If a Paleoproterozoic supercontinent broke up between 1.6 and 1.5 Ga, the distribution of sutures shows that the breakup was not complete. At least two large cratons, Atlantica (Amazonia, Congo, West Africa and probably North Africa and Rio de la Plata) and Arctica (Laurentia, Siberia, Baltica, North Australia and North China), survived the breakup and later become part of Rodinia.
