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 plateau reaches a height of 1,300 m and stands on a layer of basalt with a thickness of 2,000 m. [2] Most of the water from the plateau flows into the Río de la Plata estuary via the Paraná and Paraguay rivers. [2] Iguazu Falls is located on the western edge of the plateau.
The Paraná River (Portuguese: Rio Paraná [ˈʁi.u paɾaˈna] ⓘ; Spanish: Río Paraná [ˈri.o paɾaˈna] ⓘ; Guarani: Ysyry Parana) is a river in south-central South America, running through Brazil, Paraguay, and Argentina for some 4,880 kilometres (3,030 mi). [3] Among South American rivers, it is second in length only to the Amazon River.
The plateau slopes moderately to east and south, its remarkably uniform surface interrupted only by the narrow valleys carved by the westward-flowing tributaries of the Río Paraná. The Northern Upland, the Central Hill Belt, and the Central Lowland constitute the lower terrain lying between the escarpment and the Río Paraguay.
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.
The Paraná Basin (Portuguese: Bacia do Paraná, Spanish: Cuenca del Paraná) is a large cratonic sedimentary basin situated in the central-eastern part of South America. About 75% of its areal distribution occurs in Brazil, from Mato Grosso to Rio Grande do Sul states. The remainder area is distributed in eastern Paraguay, northeastern ...
