Amazonian Craton

The Amazonian Craton is a geologic province located in South America.

It occupies a large portion of the central, north and eastern part of the continent and represents one of Earth's largest cratonic regions.

Between the two shields lies the Amazon Rift, a zone of weakness within the craton.

[3] It has been suggested that the Late Mesoproterozoic–Early Neoproterozoic aged Sveconorwegian Orogen in Fennoscandia could have been caused by a continent–continent collision between the continents of Amazonia and Baltica.

[4] The question is open if Telemarkia terrane in Norway was derived from the Amazonian Craton, but this possibility does not imply necessarily that there was a continental collision.

Approximate location of Mesoproterozoic (older than 1.3 Ga) cratons in South America and Africa. The São Luís and Luis Alves cratonic fragments (Brazil) are shown, but the Arequipa–Antofalla Craton , the Sahara Craton , and some minor African cratons are not. Other versions describe the Guiana Shield separated from the Amazonian Shield by a depression.
