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 ...
Cordierite-bearing lavas from Jaguarao, southern Brazil: Petrological evidence for crustal melts during early rifting of Gondwana
(ELSEVIER SCIENCE BV, 2010)
The Jaguarao stratoid dacites (Rio Grande do Sul, Brazil) are limited in areal extent, are comprised of about 3.2 km(3) of preserved erupted material, and outcrop only in areas of the region underlain by mylonitic and ...
Thermochronology of the Ventana Ranges and Claromecó Basin, Argentina: Record of Gondwana breakup and South Atlantic passive margin dynamics
(Pergamon-Elsevier Science Ltd, 2021-01)
The Ventana Ranges and the neighboring Claromecó basin display multiple extensional and compressional tectonic events throughout their Phanerozoic evolution. A passive continental margin setting during the early Paleozoic ...
Episodic Jurassic to Lower Cretaceous intraplate compression in Central Patagonia during Gondwana breakup
(Pergamon-Elsevier Science Ltd, 2016-12)
From Lower Jurassic to Lower Cretaceous, several intraplate compression events affected discrete sectors of Central Patagonia, under a general context of crustal extension associated with Gondwana breakup. This was ...
Palaeomagnetism and 40Ar/39Ar dating from Lower Jurassic rocks in Gastre, central Patagonia: further data to explore tectonomagmatic events associated with the break-up of Gondwana
(Geological Society Publications House, 2012-06)
Se presenta estudio paleomagnético y edades 40Ar/39Ar sobre lavas de la Formación Lonco Trapial, Macizo Norpatagónico. Se discuten resultados en el marco de desmembramiento de Gondwana.
Chronostratigraphic constraints and paleoenvironmental interpretation of the Romualdo Formation (Santana Group, Araripe Basin, Northeastern Brazil) based on palynology
(2020-12-01)
The Santana Group of the Araripe Basin is a major paleontological unit in Brazil, incorporating two important Cretaceous Konservat-Lagerstätten. The lower formations are Aptian, but the age of the uppermost Romualdo Formation ...
Supercontinent evolution and the Proterozoic metallogeny of South America
(2007)
The cratonic blocks of South America have been accreted from 2.2 to 1.9 Ga, and all of these blocks have been previously involved in the assembly and breakup of the Paleoproterozoic Atlantica, the Mesoproterozoic to ...
Denudation history of the Bocaina Plateau, Serra do Mar, southeastern Brazil: Relationships to Gondwana breakup and passive margin development
(ELSEVIER SCIENCE BV, 2010)
The Bocaina Plateau, which is situated on the eastern flank of the continental rift of southeastern Brazil, is the highest part of the Serra do Mar. Topographic relief in this area is suggested to be closely related to its ...
