Petrology of the high-Mg tonalites and dioritic enclaves of the ca. 2130Ma Alto Maranhão suite: evidence for a major juvenile crustal addition event during the Rhyacian orogenesis, Mineiro Belt, southeast Brazil.
Combined field observations, petrography, mineral chemistry, geochemistry, Nd isotopes and U–Pb zir-con data are presented for the ca. 2130 Ma Alto Maranhão suite.
