Abstract
-
The forms of Brazilian relief cannot be understood without the comprehension of what occurs with the South America relief. The structural and sculptural processes developed in Brazilian relief are straightly related with the Atlantic opening and the formation of Andes Orogenic Chains. The Meso-Cenozoic epeirogenesis unleashed the denudational processes that set a definite mark in Brazilian relief formation. The great forms are associated with structures of Cratons, Orogenic Belts and Sedimentary Basins. These great morphologies are produced by several Pre and Post-Cretaceous erosive phases under the effect of the ancient tectonic and the Cenozoic. High altimetry positions coincide with lithologies of igneous mass and rocks of high metamorphism and, downgraded reliefs sculpted on rocks of low metamorphism that suggest important effects of chemical detritions operating on the genesis of shapes of the Brazilian relief.
