A granodioritic gneiss from the Mairi complex, located on the eastern boundary of the Mundo Novo greenstone belt, exhibits a zircon evaporation minimum age of 3.04 Ga and a Nd model age of 3.2 Ga. These results constrain the occurrence of at least three major geological units in this area: the Archean Mundo Novo greenstone belt, the Archean Mairi gneisses, and the adjoining Paleoproterozoic (,2.1 Ga) Jacobina sedimentary basin. The Jacobina basin follows the same trend as the Archean structure, extending southward to the Contendas–Mirante belt, in which a similar Archean–Paleoproterozoic association appears. We postulate that during the aleoproterozoic in the eastern margin of the Gavião block, these Archean greenstone belts constituted a zone of weakness along which a late-stage orogenic sedimentary basin developed.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-01-13T11:13:53Z No. of bitstreams: 1 s2.0-S0895981102000445-main.pdf: 472306 bytes, checksum: 21a397a506dba3c54658a5fe64b34aee (MD5)Made available in DSpace on 2012-01-13T11:13:53Z (GMT).
