Resumo: | The history of palaeocontinents alternates long fragmentation to drift periods with relatively short agglutination intervals. One of the products of a Rhyacian-Orosirian orogeny was a palaeocontinent that brought together the basement of the Araçuaí-West Congo orogen (AWCO) with regions now located in the São Francisco and Congo cratons. From ca. 2 Ga to ca. 0.7 Ga, this large region of the São Francisco-Congo palaeocontinent was spared of orogenic events, but underwent at least five taphrogenic events recorded by anorogenic magmatism and/or sedimentation. The taphrogenic events are well documented in the AWCO proximal portions and neighboring cratonic regions, but lack evidence in the AWCO high-grade core. Our studies on amphibolites intercalated in the Rhyacian Pocrane complex, basement of the Rio Doce magmatic arc, allowed to the recognition of two Mesoproterozoic taphrogenic episodes. The oldest one, a Calymmian episode, is recorded by amphibolites with a zircon magmatic crystallization age at 1529 ± 37 Ma (U-Pb SHRIMP), and lithochemical signature of basaltic magmatism related to continental intraplate settings. Another set of amphibolite bodies records the youngest taphrogenic episode, a Stenian event, with a zircon magmatic crystallization age at 1096 ± 20 Ma (U-Pb SHRIMP), and lithochemical signature similar to mature magmatism of continental rift setting. The Calymmian episode (ca. 1.5 Ga) correlates to the Espinhaço II basin stage and mafic dikes of the northern Espinhaço, Chapada Diamantina and Curaçá domains, while the Stenian episode (ca. 1.1 Ga) correlates to the Espinhaço III basin stage. We also present U-Pb data for 87 detrital zircon grains from a quartzite lens intercalated in the Pocrane complex, the Córrego Ubá quartzite. Its age spectrum shows main peaks at 1176 ± 21 Ma (35%), 1371 ± 30 Ma (18%), 1536 ± 22 Ma (19%), 1803 ± 36 Ma (17%) and 1977 ± 38 Ma (12%), suggesting a Stenian (ca. 1176 Ma) maximum depositional age (although only one zircon with low discordance shows an age of 955 ± 66 Ma). Comparing with data from the western sector of the Araçuaí orogen and São Francisco craton, it is noteworthy that no igneous zircon from the three samples yielded an age older than early Orosirian (~2.05 Ga), showing age spectra essentially limited in the range of ca. 1–2 Ga; i.e., younger than the Late Rhyacian orogeny that amalgamated the basement, and older than the main anorogenic event (930–870 Ma) associated with the Early Tonian precursor basin of AWCO. All together, these continental taphrogenic events testify the several unsuccessful fragmentation attempts that affected the long-lived São Francisco-Congo palaeocontinent, which remained preserved from a complete break-up associated with ocean spreading from the Early Orosirian to the Atlantic opening in Cretaceous time. |

Um dos produtos de uma orogenia riaciana-orosiriana foi o paleocontinente São Francisco-Congo, representado nos crátons homônimos e no embasamento do Orógeno Araçuaí-Congo Ocidental (AWCO). Durante o período de ca. 2 Ga até ca. 0,7 Ga, aquela extensa região paleocontinental foi poupada de eventos orogênicos, mas por outro lado foi submetida a pelo menos cinco eventos tafrogênicos registrados por magmatismo anorogênico e sedimentação. Tais eventos tafrogênicos estão bem registrados nas zonas proximais do AWCO e regiões cratônicas adjacentes, mas suas evidências no núcleo de alto grau do AWCO são muito mais raras. Nossos estudos sobre lentes anfibolíticas intercaladas em ortognaisses do Complexo Pocrane, embasamento do Arco Magmático Rio Doce, permitiram reconhecer dois eventos tafrogênicos mesoproterozoicos distintos. O mais antigo deles, do Caliminiano, é caracterizado por anfibolitos com zircões cristalizados em 1529 ± 37 Ma (U-Pb SHRIMP). Outro conjunto de anfibolitos registra episódio tafrogênico mais jovem, do Esteniano, com zircões de idade magmática em 1096 ± 20 Ma (U-Pb SHRIMP). O episódio calimiano (ca. 1,5 Ga) é correlato com a bacia Espinhaço II e diques máficos dos domínios Espinhaço, Chapada Diamantina e Curaçá, enquanto o episódio esteniano (ca. 1,1 Ga) se correlaciona com a bacia Espinhaço III. Dados U-Pb de 87 grãos detríticos de zircão coletados em lentes do Quartzito Córrego Ubá, intercaladas no Complexo Pocrane, mostram um espectro de idades com picos em 1176 ± 21 Ma (35%), 1371 ± 30 Ma (18%), 1536 ± 22 Ma (19%), 1803 ± 36 Ma (17%) e 1977 ± 38 Ma (12%). Apesar de se ter encontrado um zircão com idade de 955 ± 66 Ma, o tratamento estatístico dos dados sugere a idade máxima de deposição em ca. 1176 Ma. O espectro de idades mostra-se essencialmente limitado no intervalo 1–2 Ga, contrastando com os dados do setor oeste do AWCO e do Cráton São Francisco, onde são comuns zircões do Toniano ou mais velhos que 2 Ga. Isso sugere uma bacia alimentada por fontes relativamente restritas. Os dois eventos tafrogênicos mesoproterozoicos aqui reportados evidenciam duas das tentativas de fragmentação mal sucedidas que incidiram sob o Paleocontinente São Francisco-Congo, o qual resistiu à completa fragmentação desde ca. 2 Ga até a abertura do Oceano Atlântico no Cretáceo.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIABrazilian Journal of GeologyBacias sedimentaresTempo geologicoOrogeniaTaphrogenic eventsSão Francisco-Congo palaeocontinentAraçuaí-West Congo orogenyRecords of Mesoproterozoic taphrogenic events in the eastern basement of the Araçuaí Orogen, southeast BrazilRegistros de eventos tafrogênicos mesoproterozoicos no embasamento do Orógeno Araçuaí, sudeste do Brasilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/bjgeo/a/shDFfJTm3gL7qkQ4ydZjB3F/?lang=enTobias Maia Rabelo Fonte-BoaTiago Amâncio NovoAntônio Carlos Pedrosa-SoaresIvo Antonio Dussinapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;

The history of palaeocontinents alternates long fragmentation to drift periods with relatively short agglutination intervals. One of the products of a Rhyacian-Orosirian orogeny was a palaeocontinent that brought together the basement of the Araçuaí-West Congo orogen (AWCO) with regions now located in the São Francisco and Congo cratons. From ca. 2 Ga to ca. 0.7 Ga, this large region of the São Francisco-Congo palaeocontinent was spared of orogenic events, but underwent at least five taphrogenic events recorded by anorogenic magmatism and/or sedimentation. The taphrogenic events are well documented in the AWCO proximal portions and neighboring cratonic regions, but lack evidence in the AWCO high-grade core. Our studies on amphibolites intercalated in the Rhyacian Pocrane complex, basement of the Rio Doce magmatic arc, allowed to the recognition of two Mesoproterozoic taphrogenic episodes. The oldest one, a Calymmian episode, is recorded by amphibolites with a zircon magmatic crystallization age at 1529 ± 37 Ma (U-Pb SHRIMP), and lithochemical signature of basaltic magmatism related to continental intraplate settings. Another set of amphibolite bodies records the youngest taphrogenic episode, a Stenian event, with a zircon magmatic crystallization age at 1096 ± 20 Ma (U-Pb SHRIMP), and lithochemical signature similar to mature magmatism of continental rift setting. The Calymmian episode (ca. 1.5 Ga) correlates to the Espinhaço II basin stage and mafic dikes of the northern Espinhaço, Chapada Diamantina and Curaçá domains, while the Stenian episode (ca. 1.1 Ga) correlates to the Espinhaço III basin stage. We also present U-Pb data for 87 detrital zircon grains from a quartzite lens intercalated in the Pocrane complex, the Córrego Ubá quartzite. Its age spectrum shows main peaks at 1176 ± 21 Ma (35%), 1371 ± 30 Ma (18%), 1536 ± 22 Ma (19%), 1803 ± 36 Ma (17%) and 1977 ± 38 Ma (12%), suggesting a Stenian (ca. 1176 Ma) maximum depositional age (although only one zircon with low discordance shows an age of 955 ± 66 Ma). Comparing with data from the western sector of the Araçuaí orogen and São Francisco craton, it is noteworthy that no igneous zircon from the three samples yielded an age older than early Orosirian (~2.05 Ga), showing age spectra essentially limited in the range of ca. 1–2 Ga; i.e., younger than the Late Rhyacian orogeny that amalgamated the basement, and older than the main anorogenic event (930–870 Ma) associated with the Early Tonian precursor basin of AWCO. All together, these continental taphrogenic events testify the several unsuccessful fragmentation attempts that affected the long-lived São Francisco-Congo palaeocontinent, which remained preserved from a complete break-up associated with ocean spreading from the Early Orosirian to the Atlantic opening in Cretaceous time. |
