Formed between the Mesozoic and Cenozoic, Brazil has numerous offshore basins that contain oil, related to the rifting of the Atlantic Ocean. The Sergipe-Alagoas Basin is an example of Aptian age shale, conglomerate and sandstone deposited in the final phase of rifting, while the Miranga, Aracas, Dom Joao and Agua Grande fields reflect mid ...
The Brazilian Highlands or Brazilian Plateau (Portuguese: Planalto Brasileiro) is an extensive geographical region covering most of the eastern, southern and central portions of Brazil, in all some 4,500,000 km 2 (1,930,511 sq mi) or approximately half of the country's land area.

In the north, a large area is occupied by the Amazonian lowland. To the south of it is the strongly dissected Brazilian lowland. Between the Brazilian lowland and the Atlantic Ocean is a narrow coastal lowland. Brazil has large deposits of oil, iron, bauxite, nickel, uranium, manganese ores, diamonds and other minerals.
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.
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).
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.
