“…This is largely comprised of Neoproterozoic metasedimentary units in which deformation and metamorphism decrease eastwards towards the São Francisco Craton. Northwards, these Neoproterozoic units (see Dardenne 2000 for a comprehensive review) lie unconformably over Paleoproterozoic basement units containing minor Archean contribution (Correia et al 1997, Sato 1998, Pimentel et al 2000a, Cruz et al 2000. It has been suggested that these rocks may represent the western extension of the São Francisco Craton.…”

“…It comprises: (i) a thick Meso-Neoproterozoic metasedimentary/ sedimentary pile with eastward tectonic vergence; (ii) a large Neoproterozoic juvenile arc in the west (Goiás Magmatic Arc); and (iii) a micro-continent (or exotic sialic terrain) formed by Archean rock units (the Crixás-Goiás granite-greenstones) and as-sociated Proterozoic formations (Almeida et al 1981, Fuck et al 1993, Pimentel et al 2000a (Figure 1) .…”

“…The sedimentary sequence of Bambuí Group records a major transgression in a foreland marine basin generated in the overload caused by Neoproterozoic mobile belts, especially the thrust and crustal pressures of Brasília orogen along the West part of the São Francisco Craton (Alkmim & Martins-Neto, 2001Martins-Neto et al, 2001;Martins-Neto, 2005, 2009, as the product of arc-continent and continent-continent collision between 800 and 550 Ma (Pimentel et al, 1999). Seismic data of this unit indicate thicknesses of about 4 km to the West and about 800 m to the East of the São Francisco Craton, near the flexural edge (Martins-Neto, 2005).…”

“…O Orógeno Tocantins, Província Tocantins (Almeida 1977), representa o registro inicial da estruturação do Gondwana Ocidental, iniciada a 750 M.a. (Pimentel et al 1999). Essa envolveu a convergência das placas Amazônia e Rio de la Plata contra a Placa São Francisco-Congo e o fechamento do Oceano Brasilides (Alkmim et al 2001, Dardenne 2000, Pimentel et al 2000, Trouw et al 2000, com registros dos episódios de subducção e colisão (Brito Neves 1999, em panorama de fechamento do Oceano Goianides, de idade toniana, posicionado a oeste da Placa Sanfranciscana, no Neoproterozoico (Fig 1A), e na sua porção meridional (Fig.…”
