Ferroan granites (585–530 Ma) have been described in the Transversal subprovince of the Borborema Province (BP) and in Pan-African counterparts. They comprise two groups: Group 1 – slightly peraluminous to metaluminous, alkali-calcic rocks, with

The Pilõezinhos Pluton (PP). comprises a ~100 km2-elongated intrusion in the NE part of the Transversal Domain of the Borborema Province. It is composed of monzogranites and syenogranites, subdivided into two distinct petrographic facies. The PP int
