本文试图证明原来的概念，圣弗朗西斯科翁，并确定其限制。在巴西周期期间，这一区域几乎覆盖了整个巴伊亚州和附近的米纳斯吉拉斯、戈亚斯、伯南布哥和塞尔吉佩州的部分地区。本文描述了位于南海南部和东南部边界的阿拉瓜伊褶皱带，其构造与Macaubas群相对应。本文讨论了相邻折叠带的边界的性质。建议建立这些界限沿着明显的边缘故障。合理的推论，他们之间提交。
This paper is an attempt to justify the original concept of the Sao Francisco Craton and to define its limits. This Craton covered almost the entire State of Bahia and parts of the near Minas Gerais, Goias, Pernambuco and Sergipe States during the Brasiliano Cycle. The authol characterizes the Aracuai folded belt whose structures correspond to the Macaubas 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.
