Tectonic controls on the building of the North Patagonian fold-thrust belt (~43°S)
(Elsevier, 2019)
In active continental margins, mountain building processes have been classically referred to as Andeantype orogenesis (e.g., Uyeda and Kanamori, 1979) wherever the coupling between an oceanic plate subductedbeneath a ...
Tectonic Evolution of the Central Andes: From Terrane Accretion to Crustal Delamination
(AAPG, 2018)
The analysis of the pre-Andean history of the Central Andes shows a complex tectonic evolution. The basement of the Andean continental margin was formed by the accretion of Precambrian blocks during the formation of Rodinia ...
Lower Jurassic to Early Paleogene Intraplate Contraction in Central Patagonia
(Springer International Publishing, 2018)
Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onwards, a process that was interrupted by the ...
Orogenic Growth of the Fuegian Andes (52–56°) and Their Relation to Tectonics of the Scotia Arc
(Springer, 2016)
The tectonic evolution of the Fuegian Andes is strongly related to their southern neighbors, the Scotia Sea and Antarctica. During Mesozoic times, extensional and magmatic processes in the southernmost Andes developed in ...
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. ...
Neogene tectonic evolution of the Neuquén Andes western flank (37–39°S)
(Geological Society of America, 2006)
This paper integrates data to summarize the evolution of the 37-39°S segment of the Andean margin from the Miocene to Present. The western Neuquén Andes represent a transitional segment between the high, broad Central Andes ...
Controls on Deposition of the Tordillo Formation in Southern Mendoza (34°–36° S): Implications for the Kimmeridgian Tectonic Setting of the Neuquén Basin
(Springer, 2020)
The Tordillo Formation is a continental succession of red beds deposited in the Neuquén basin during the Kimmeridgian. Based on sedimentological and structural evidence we document an extensional setting between 34˚ and ...
The syn-rift of the Neuquén Basin (Precuyano and Lower Cuyano Cycle): Review of structure, volcanism, tectono-stratigraphy and depositional scenarios
(Springer, 2020)
The Neuquén Basin is constituted by a system of NW-SE rift clusters formed during the Late Triassic–Early Jurassic at the western margin of Gondwana. The rifting is the result of an extensional tectonic regime triggered ...
Tectono-Stratigraphic Evolution of the Atuel Depocenter During the Late Triassic to Early Jurassic Rift Stage, Neuquén Basin, West-Central Argentina
(Springer, 2020)
The Neuquén basin presents an almost continuous record from the Late Triassic until the Paleocene,making it an excellent case study of the most relevant tectonic stages of southern South America during the Mesozoic. It was ...
