Congo-São Francisco craton in Paleoproterozoic-Mesoproterozoic supercontinent Nuna
The location of the Congo-São Francisco (CSF) craton, one of the largest cratons in Proterozoic paleogeography, has been poorly constrained for the supercontinent Nuna interval (ca. 1800–1300 Ma). Initial models of Nuna suggested that the CSF craton was part of the Atlantica continent, together with Amazonia, West Africa, and perhaps Río de la Plata, as a separate continental block from other Nuna
