New insights of the tectonic and sedimentary evolution of the Rio Grande Rise, South Atlantic Ocean
(2019-12-01)
Oceanic plateaus, such as the Rio Grande Rise (RGR), comprise crucial pieces of information about the opening of the South Atlantic Ocean and the evolution of associated lithospheric plate margins. A detailed seismostratigraphic ...
Lower Jurassic felsic diatreme volcanism recognized in central Patagonia as evidence of along-strike rift segmentation
(Pergamon-Elsevier Science Ltd, 2020-06-14)
The early Jurassic volcanism of Central Patagonia covers an extensive area of50,000 km2 where the volcanic deposits occur as isolated systems. The volcanicrecords form an elongated belt in which the composition, depositional ...

Unraveling the origin of the Parnaíba Basin: Testing the rift to sag hypothesis using a multi-proxy provenance analysis
(2020-08-01)
Syneclises are long-lived sedimentary basins characterized by complex subsidence and erosion histories. The premise that these geotectonic units evolve from initial rifting processes following thermal (or flexural) subsidence ...
Ages of pre-rift basement and synrift rocks along the conjugate rift and transform margins of the Argentine Precordillera and Laurentia
(Geological Society of America, 2012-10)
New geochronologic data from basement rocks support the interpretation that the Argentine Precordillera (Cuyania) terrane was rifted from the Ouachita embayment of the Iapetan margin of Laurentia. New data from the Ozark ...
