BRASILIAN RELIEF: STRUCTURES AND FORMS

Resumo

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.
