Provenance of the Vazante Group: New U-Pb, Sm-Nd, Lu-Hf isotopic data and implications for the tectonic evolution of the Neoproterozoic Brasilia Belt

Rodrigues, J.B.; Pimentel, Marcio M.; Buhn, B.; Matteini, Massimo; Dardenne, M.A.; Alvarenga, C.J.S.; Armstrong, Richard


The Vazante Group show varied U-Pb provenance patterns along the basin. Zircon ages range from 936 to 3409Ma, but Paleo- and Mesoproterozoic terrains constitute the main sources of the original sediments. The youngest population (~930Ma) establishes the maximum depositional age of the group. Sm-Nd T DM data show the predominance of Paleoproterozoic ages (1.90-2.08Ga) and also indicate some input from younger sources in rocks of the Lapa Formation (1.67 to 2.0Ga) in the upper part of the group,...[Show more]
