In the southern portion of the Borborema Province, in the Sergipano Orogenic System, three basement inliers have been described: the Domes of Itabaiana and Simão Dias, in Sergipe; and the Girau do Ponciano Dome, in Alagoas. The Itabaiana and Simão Dias Domes occur in the central part of the Vaza Barris Domain, being composed of gneisses and migmatites. The Itabaiana rocks are calc-alkaline with trondhjemitic affinities. The Girau do Ponciano Dome, outcropping in the Macururé Domain, consists mainly of tonalitic, dioritic, monzonitic, granodioritic and highgrade granitic orthogneisses. SHRIMP U-Pb zircon date of a melanosome sample from a trondhjemitic migmatitic gneiss in the central part of Itabaiana Dome provided an age of 2831 ± 6 Ma, indicating that the migmatitic gneisses of this dome are correlated to the Mesoarchean terranes of the São Francisco Craton (Serrinha Block). These rocks represent the oldest geological record in the Sergipe State.
