SUMMIT SURFACES IN BRAZIL

AZIZ NACIB AB'SÁBER

Resumo


The study of summit planation surfaces and that of inter-plateau planations constitute together one of the most important themes of topographic meso-compartmentation of Brazil. Such planations, on the top of pre-Cambrian terranes, constitute extensive leveling processes of complex structures, later submitted to epeirogenetic uplift of the type called by French authors epirogenese par sacades. In the present work is epitomized the available information on these old planations, usually taken as post-Gondwana - credit is given to pioneer researchers (E.C.Harder and R.T. Chamberlin, E. De Martonne, R. O. de Freitas, F.F.M. de Almeida, Lester King). The study of these planations constitutes a radical transilience from geological history proper into post-Cretaceous geomorphological history of a large part of Brazil.
