New U-Pb results demonstrate that this association is Neoproterozoic andKeywords: amphibolite; geochronology; island arc; magmatism; metapelite; Proterozoic; Anicuns; Brazil; Goias; South America Goiás magmatic arc; Mafic rocks; Neoproterozoic; Sm-Nd/isotopes; U-Pb geochronologyMafic magmatism associated with the Goi's magmatic arc in the Anicuns region, Goi's, central Brazil: Sm-Nd isotopes and new ID-TIMS and SHRIMP U-Pb data200410.1016/j.jsames.2003.11.0012015-12-11
