ALTERNATING CONTRACTION AND EXTENSION IN THE SOUTHERN CENTRAL ANDES (35 degrees-37 degrees S)
(2019)
The Andes are thought to be formed through discrete contractional stages separated by periods of little to no orogenic construction. This paper analyzes the intervals between the main contractional phases that built the ...
Extensional tectonics in the Paraíba do Sul belt, northwestern part of the Rio de Janeiro: structural analyses along the Itaperuna (RJ)-Muriaé (MG) sectionTectônica extensional no cinturão Paraíba do Sul no noroeste do Rio de Janeiro: análise estrutural na seção Itaperuna (RJ) – Muriaé (MG)

Large extensional aftershocks in the continental forearc triggered by the 2010 Maule earthquake, Chile
(WILEY-BLACKWELL, 2012-03)
The Mw 8.8 Maule earthquake occurred off the coast of central Chile on 2010 February 27
and was the sixth largest earthquake to be recorded instrumentally. This subduction zone event
was followed by thousands of aftershocks ...
Tectonic evolution of the Neoproterozoic Tandilia sedimentary cover, Argentina: New evidence of contraction and extensional events in the southwest Gondwana margin
(Pergamon-Elsevier Science Ltd, 2017-11)
At the northwestern portion of the Tandilia System, a detailed structural analysis on the Precambrian sedimentary units exposed in the quarries of the Olavarría-Sierras Bayas area was carried out. These units exhibit ...
Lower paleozoic ‘El Nihuil Dolerites’: Geochemical and isotopic constraints of mafic magmatism in an extensional setting of the San Rafael Block, Mendoza, Argentina
(Springer, 2017)
The ‘El Nihuil Mafic Unit’ is exposed at the Loma Alta region northwards of the El Nihuil dam. This igneous body consists mainly of mafic rocks assigned to the Precambrian and Lower Paleozoic according to different authors. ...
Recurring extensional and strike-slip tectonics after the Neoproterozoic collisional events in the southern Mantiqueira province
(Academia Brasileira de Ciências, 2012)
In Eastern South America, a series of fault-bounded sedimentary basins that crop out from Southern Uruguay to Southeastern Brazil were formed after the main collisional deformation of the Brasiliano Orogeny and record the ...
Late Oligocene-early Miocene submarine volcanism and deep-marine sedimentation in an extensional basin of southern Chile: Implications for the tectonic development of the North Patagonian Andes
(2016)
The Chilean margin has been used as the model of an ocean-continent convergent system dominated by compression and active mountain building as a consequence of the strong mechanical coupling between the upper and the lower ...
