    Cratons whose ancient rocks are widely exposed at the surface, often with relatively subdued relief, are known as shields. If the ancient rocks are largely overlain by a cover of younger rocks then the 'hidden' craton may be referred to as a platform .

    West Africa. The craton appears to have formed when three Archean cratons fused: Leo-Man-Ghana, Taoudeni and Reguibat. The first two docked around 2.1 Ga (billion years ago), and the Reguibat Craton docked with the craton around 2 Ga.

    Smaller cratons of Precambrian rocks south of the Amazonian Shield are the Río de la Plata Craton and the São Francisco Craton, which lies to the east. The Río Apa Craton at the Paraguay-Brazil border is considered to be likely just the southern part of the Amazonian Craton. [2] The rocks of Río Apa were deformed during the Sunsás orogeny. [3]

    He derived the map based on the age of the greenstone belts found in the Craton. He suggested that the greenstone belt was formed by collision of some micro blocks. [19] [20] [21] The green belt on the map shows a younger greenstone belt, formed 2.5 billion years ago, while the yellow one showed the greenstone belt formed 2.6–2.7 billion ...
