“…Barro Alto, Niquelândia and Cana Brava are three mafic-ultramafic layered complexes, which outcrop in a 350 km NNE trend alignment within the Brasilia Belt in the northern Goiás (central Brazil). They share several field, stratigraphic, geochemical and geochronological features that led to their interpretation as a cogenetic and coeval large intrusion (Ferreira Filho et al, 1998;Carminatti, 2006;Giovanardi et al, 2016). In contrast, several authors claim that Barro Alto and Niquelândia were both formed by two different intrusive events (a Meso-and a Neo-Proterozoic intrusion, with Cana Brava belonging to the Neoproterozoic event; Pimentel et al, 2004Pimentel et al, , 2006Ferreira Filho et al, 2010;Della Giustina et al, 2011).…”
