Basement-cover relationships and deformation in The Northern Paraguai Belt, central Brazil: Implications for the Neoproterozoic-early palaeozoic history of western Gondwana

The Northern Paraguai Belt, at the SE border of the Amazonian Craton, central Brazil, has been interpreted as a Brasiliano/Pan-African (ca. 650-600 Ma) belt with a foreland basin, recording collisional polyphase tectonism and greenschist facies metamorphism extending from the late Precambrian to the Cambrian-Ordovician. New structural investigations indicate that the older metasedimentary rocks of the Cuiaba Group represent a Tonian-Cryogenian basement assemblage deformed in two contemporaneous fault-bounded structural sub-domains of wrench- (rake
