Evolution of polycyclic basement complexes in the Araçuaí Orogen, based on U-Pb SHRIMP data: Implications for Brazil-Africa links in Paleoproterozoic time

Noce, Carlos M; Pedrosa-Soares, Antônio Carlos; da Silva, Luiz Carlos; Armstrong, Richard; Piuzana, Danielle

Description

Paleoproterozoic basement of the Araçuaí Orogen is composed of amphibolite and granulite facies orthogneiss units known as Mantiqueira and Juiz de Fora complexes. Six U-Pb SHRIMP crystallization ages for the Mantiqueira Complex range from 2137 ± 19 to
