In the region of Julio Borges, in the south of Piauí State, there are a lot of manganese occurrences that are associated with the rocks of the Crístalândia Piauí Complex (Archean / Paleoproterozoic) and of the Orogen Rio Preto, structured in the Neoproterozoic. The main aim of this work corresponds to a geological mapping in the scale 1:25.000, carried out in order to establish the configuration of the enclosing geological framework and to identify the main manganese occurrences in the Julio Borges region. Map produced shows the rocks of the Crístalândia of Piauí Complex occur at the longitudinal edges of the area, bordering the thin occurrence strip of the metasedimentary rocks of the named Rio Preto Group, and the Cenozoic sedimentary roc...
