G'day Gondwana - the final accretion of a supercontinent: U-Pb ages from the post-orogenic Sao Vicente Granite, northern Paraguay Belt, Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The Paraguay Belt in central South America is part of a larger chain of orogenic belts, including the Araguaia Belt to the northeast and potentially the Pampean Belt to the south, which are believed to mark the suture zone ...
Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle
(Elsevier Science, 2017-11)
Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamic scenario assumed for the period ...
