New SHRIMP U-Pb zircon ages combined with Sm-Nd isotopic characteristics of granulites and associated granitic rocks of the Anapolis-Itaucu Complex in the central-southern part of the Brasilia Belt are presented and discussed in this study. Igneous crystallization ages obtained in zircon grains of orthogranulite and granites vary between 760 and 650Ma. Growth of new zircon at ca. 650-640Ma dates the...
