“…The basal Paranoá-Upper Espinhaço sequence consists of continental sediments and volcanic rocks associated with anorogenic plutons. Mesoproterozoic anorogenic magmatism associated with multiple rifting episodes might represent a manifestation of the Columbia supercontinent breakup, which started around 1.6 Ga and ended between 1.3 and 1.2 Ga (Reis et al, 2017a, b [41,42]). The Espinhaço Supergroup is exposed on the East of the São Francisco Basin.…”

“…One could expect that the deep-rooted faults in the graben structures (Precambrian sequence), which have been reactivated during the Neoproterozoic Macaúbas basin-cycle, could cross most of the sedimentary formation. As a major fault system, they may control the drainage at all depths and delineate some morphological features observed on satellite imagery and digital elevation models (Reis et al, 2017b [42]).…”

“…O Grupo Bambuí é composto de ciclos de sedimentação de caráter carbonático e pelito-arenoso, cujos depósitos são correlacionados a uma extensa transgressão marinha de idade neoproterozoica que avança sobre o Cráton do São Francisco (Alkmim e Martins-Neto, 2012). A bacia de deposição é interpretada dentro do contexto de bacia foreland (Alkmim et al, 1989;Reis et al, 2017a), com deformação incipiente, em condições de tectônica epidérmica, atingindo fácies metamórfica xisto-verde baixo ao longo das faixas de dobramentos brasilianas (Magalhães, 1989;Marshak e Alkmim, 1989). A divisão estratigráfica do grupo proposta por Costa e Branco (1961) foi adaptada por Dardenne (1978), que individualiza da base para o topo: a Sete Lagoas, com calcários, dolomitos, margas e siltitos calcíferos; a Serra de Santa Helena, com arenitos finos e ritmitos pelíticos; os calcários escuros e oolíticos e margas da Lagoa do Jacaré; a Serra da Saudade, composta de argilitos que passam gradualmente para os siltitos arcoseanos; e os arcóseos finos da Formação Três Marias.…”
