ABSTRACT The Urucum Suite granitoids (Rio Doce region, southeastern Brazil) contains four main facies: megafeldspar granites, deformed medium- to coarse-grained granites,

Sr and Nd isotopic data available for the Urucum suite granitoids are similar to those obtained for syn-collisional granites (suite G 2 of Pedrosa-Soares & Wiedemann-Leonardos

Two different facies were identified for Carbomil Well: bioclastic packstones to wackstones (sections C2, C4, C5, C6 and C7), representing a marine brackish or restricted
