Highlights • Long-lived subduction, convergent margin magmatism in São Francisco Paleocontinent • Four accretion episodes ca. 2.52–2.46 Ga, 2.43–2.37 Ga, 2.32–2.26 Ga, 2.24–2.20 Ga. • Evolution from dominant Siderian juvenile magmatism to Rhyacian crustal magmatism • Magmatic flare-up and quiescence during the Siderian-Rhyacian magmatic lull • Sy...
Article
Some of Proterozoic basin data are commonly difficult to assess due to the complexity of tectonic processes and lack of volcanic rocks and fossil record. The Mesoproterozoic Paranoá Basin in Central Brazil was investigated through stratigraphic framework integration, depositional environmental analysis and with detrital zircon and statistical analy...

The evolution of land plants during the Palaeozoic Era transformed Earth’s biosphere 1. Because the Earth's surface and interior are linked by tectonic processes, the linked evolution of the biosphere and sedimentary rocks should be recorded as a near-contemporary shift in the composition of the continental crust. To test this hypothesis, we assess...

New and compiled detrital zircon U–Pb ages from the southern Neoproterozoic-Cambrian Ribeira Belt, SE Brazil, demonstrate Laurentian affinity of the Embu Terrane which is statistically distinct from the adjoining Apiaí and São Roque terranes with cratonic affinity (e.g., São Francisco Craton). Zircon provenance results indicate that the type-area o...

Article available at: https://authors.elsevier.com/c/1aZdVhdGqSQLI The Neoproterozoic Araçuaí belt of eastern Brazil formed during the amalgamation of Western Gondwana and holds characteristics of a hot collisional belt, involving large amounts of magma, partial melting of the middle crust, and slow cooling rates. To improve our understanding of...

Formações ferríferas bandadas (BIF - Banded Iron Formation) são rochas sedimentares químicas, caracterizadas por serem acamadadas ou laminadas, definidas por uma alternância de minerais ricos em ferro (20-40%) e minerais silicatados pobres em ferro (40-50%) (Klein, 2005; Posth 2011). As formações ferríferas são de grande importância econômica, hosp...

A partir de novos dados coletados em mapeamento geológico em escala de detalhe (1:50.000), espera- se contribuir para o conhecimento geológico acerca da evolução tectônica e preenchimento da Bacia Natividade.Os dados litoestratigráficos levantados indicam que a deposição da sequência sedimentar está condicionada a ambiente marinho com subambientes...

We aim to investigate the timing and nature of several terrane accretions that occurred in the western margin of the São Fracinsco Craton from 2.5 to 2.2 Ga, a period that is globally described as the Siderian-Rhyacian quiet interval, magmatic lull or tectonic slowdown.
