Convergent plate tectonics within the continent of Gondwana had a major influence in the Paleozoic. [9] The Maranhao intracratonic basin in Piaui and Maranhao, close to the mouth of the Amazon spans 600,000 square kilometers and filled with 2.5 kilometers of sandstone and shale from the Cambrian through the Devonian.

The journal covers the field of geology and related earth sciences, in Brazil, South America, and Antarctica, including oceanic regions adjacent to these regions. [1] The journal was established in 1971 and articles are published in English and Portuguese. The journal replaced the Boletim da Sociedade Brasileira de Geologia established in 1952.
The Pernambuco Fault in this domain is a continuation of the Foumban Shear Zone in Cameroon, itself the western end of the Central African Shear Zone. [1] To the west, the fault splays into numerous faults along a distance of about 50 kilometres (31 mi), suggesting that the crust was weak at this point, which is on the line where South America ...

The basalt samples at Paraná and Etendeka have an age of about 132 Ma, during the Valanginian stage of the Early Cretaceous. [3] Indirectly, the rifting and extension are probably the origin of the Paraná and Etendeka traps and it could be the origin of the Gough and Tristan da Cunha Islands as well, as they are connected by the Walvis Ridge (Gough/Tristan hotspot).
