Abstract Four main classes of tectonic entities may be considered for the Ribeira Belt and southwest African counterparts: (1) cratonic fragments older than 1.8 Ga their passive margin successions, (2) reworked basement terranes with Mesoproterozoic and/or Neoproterozoic deformed cover, (3) magmatic arc associations, (4) Palaeoproterozoic back-arc successions. Based on comparative investigation, a model polyphase amalgamation is proposed c . 790 630–610 Ma major episodes intra-oceanic...
Abstract The Brasília Belt comprises terranes and thrust-sheets that were tectonically transported towards the western passive margin of São Francisco–Congo palaeocontinent during an orogenic episode resulting from collision Paranapanema Goiás blocks magmatic arc against at 0.64–0.61 Ga. tectonic zones belt are, east to west: a foreland zone with Archaean–Palaeoproterozoic granite–greenstone basement covered by Neoproterozoic anchimetamorphic sedimentary rocks (Bambuí Group); low metamorphic...
The southern portion of the São Francisco Palaeocontinent in Brazil is denoted by Archean nuclei and Paleoproterozoic magmatic arcs that were amalgamated during Siderian to Orosirian orogenic processes (ca. 2.4–2.1 Ga). New isotopic U–Pb zircon Sm–Nd whole rock combined with major trace element composition analyses constrain crystallization history Neoarchean Piedade block (at ca. 2.6 Ga) Mantiqueira Complex 2.1–1.9 These therefore display quite different histories prior their amalgamation...
Abstract This chapter presents a synthesis of the pre-break-up plate tectonics western Gondwana and pre- syn-rift magmatism in SW South Atlantic margin (Brazil, Uruguay Argentina) conjugate African continental (Angola, Namibia Africa). An updated database geographical locations primary available radiometric ages is also included this work. A systematic analysis K–Ar Ar/Ar from outcrops boreholes shows marked Mid to Late Jurassic peak southernmost segment Atlantic, related emplacement Karoo...
A comprehensive tectonic evolution of Proterozoic to Cambrian rocks that integrate the crystalline basement Rio de Janeiro State, based on new geological map, is presented. The map combines detailed data integrated a 1:400.000 scale and geochemical geochronology characterize distinct terranes amalgamated during three pulses Brasiliano orogeny. Occidental terrane comprises Tonian Late Cryogenean passive margin São Francisco paleocontinent, including reworked cratonic basement. At same period,...
A robust elemental and isotopic dataset from Neoproterozoic igneous rocks discloses protracted consumption of oceanic lithosphere in the 3,000 km long orogenic system southeastern South America.Time dependent variation trends suggest that Tonian-Cryogenian magmatic formed intra-oceanic supra-subduction settings, followed by Ediacaran arc building along Andean-type continental margins.Tectonic slices basic-ultrabasic associated with deep sea exhalative are interpreted as remnants obducted...
