O CRÁTON DO SÃO FRANCISCO

Abstract

This paper is an attempt to justify the original concept of the São Francisco Craton and to defìne its limits. This Craton covered almost the entire State of Bahia and parts of the near Minas Gerais, Goiás, Pernambuco and Sergipe States during the Brasiliano Cycle. The authol characterizes the Araçuaí folded belt whose structures correspond to the Macaúbas Group and are disposed on the southern and southeastern borders of the Craton. The nature of the limits of the Craton with the adjacent folded belts is discussed. A proposal to establish these limits along evident marginal faults with .justified inferences between them is submitted.
