Plate kinematic reconstructions show that the Farallon-Phoenix (Aluk) spreading center subducted under South America sometime between the Late Cretaceous and the Paleogene periods. Geological studies have supported a ...

During Cenozoic times, Patagonia was characterized by an intense magmatic intraplate activity that gave rise to a large volume of basaltic flows and intrusive bodies. This work aims to gather all the available information ...

The origin, extent, and timing of intraplate contraction in Patagonia are among the least understood geological processes of southern South America. Particularly, the intraplate Deseado fold-thrust belt (FTB), located in ...

This paper presents a review on the geotectonic framework of the Southeastern Brazil and neighborhoods, and its importance in the regional geologic evolution, which was exposed as a main conference at the XI Symposium of ...

The Late Jurassic Aguilar pluton is located in NW Argentina, about 300–400 Km east of the Tarapacá basin, representing the backarc basin linked to the Jurassic volcanic arc. This small-size and compositionally heterogeneous ...

The September 16, 2015, Mw 8.4 Illapel, Chile earthquake is the first large event occurring in north-central Chile after the 1943 earthquake, filling a known seismic gap in the region. The earthquake took place in a complex ...

The early Mesozoic extensional processes recognized in SW Gondwana have been related to a supercontinent precursor break-up phase, the gravitational collapse of a late Paleozoic orogen, changes in subduction dynamics or ...

The arrival and subsequent stagnation of the Farallon/Nazca slab at the mantle transition zone below southern South America triggered seemingly unrelated large-scale geological processes in the second half of the Cenozoic. ...

On 2012 May 19, an mb = 4 earthquake shook the town of Montes Claros, Brazil in the middle of the S˜ao Francisco Craton. Because of the scarce seismicity in the area, an event like this could provide valuable information ...
