Extensional tectonics and gravitational collapse in an Ordovician passive margin: The Western Argentine Precordillera
(Elsevier Science, 2008-03)
The paper describes ubiquitous extensional structures developed in a passive margin of Ordovician age in the Argentine Precordillera. These extensional structures include normal faults and boudinaged sequences. In some ...
Extensional tectonics during Late Cretaceous evolution of the Southern Central Andes: Evidence from the Chilean main range at ~35°S
(Elsevier Science, 2018-10)
The study of Late Cretaceous-earliest Paleogene series in the Chilean Andes at ~35°S provides new constraints on the coeval evolution of the area and the Southern Central Andes. These correspond to the continental series ...
Comparison of lacustrine successions and their palaeohydrological implications in two sub-basins of the Triassic Cuyana rift, Argentina
(Wiley Blackwell Publishing, Inc, 2015-12)
Continental carbonates are rich in palaeoclimatic, palaeoenvironmental and palaeontological information. While carbonate accumulation mechanisms have been described for many types of continental environments, especially ...
An Exceptional Tectonic Setting along the Andean Continental Margin
(The American Association of Petroleum Geologists, 2020-11)
The Late Jurassic?Early Cretaceous Vaca Muerta Formation deposited in the Neuquén Basinhas an exceptional development, in the thickness of its sequences and in the volume ofits sedimentaryrecord. These marine deposits, ...
Basic magmatism in northeastern Puna, Argentina: Chemical composition and tectonic setting in the Ordovician back-arc
(Pergamon-Elsevier Science Ltd, 2009-12)
Two main groups of basic rocks, representative of the bimodal Ordovician magmatism of the northeastern Puna (22-24°S, 66°30'-65°40'W) were revisited on the basis of new geological, petrographic and geochemical data. One ...
Allogenic controls on the fluvial architecture and fossil preservation of the Upper Triassic Ischigualasto Formation, NW Argentina
(Elsevier Science, 2017-12)
The Upper Triassic Ischigualasto Formation in NW Argentina was deposited in a fluvial system during the synrift filling of the extensional Ischigualasto-Villa Unión Basin. The expansive exposures of the fluvial architecture ...
Geochemical constraints on the petrogenesis of Triassic alkaline basalts of Sierra de Valle Fértil, Western Sierras Pampeanas, Argentina: implications for their origin, evolution and tectonic setting
(Pergamon-Elsevier Science Ltd, 2019-11)
The first geochemical and Sr-Nd isotope data of a series of Triassic basaltic rocks from Sierra de Valle Fértil, Western Sierras Pampeanas, Argentina, are herein presented. The mafic rocks are the result of continental ...
The tectonic regime along the Andes: Present-day and Mesozoic regimes
(John Wiley & Sons Ltd, 2010-01)
The analyses of the main parameters controlling the present Chile-type and Marianas-type tectonic settings developed along the eastern Pacific region show four different tectonic regimes: (1) a nearly neutral regime in the ...
Late triassic- Early jurassic continental extension in SouthWestern Gondwana: Tectonic segmentation and pre-break-up rifting
(Pergamon-Elsevier Science Ltd, 2001-04)
From the earliest Jurassic to the Cenozoic, the Neuquén Basin (central Argentina and Chile) evolved as an intra-arc and transarc-retroarc depression through the gradual development of the Andean magmatic arc. However, the ...
Tectonostratigraphic significance of the neogene sedimentary record of northwestern Austral-Magallanes Basin, Argentinean Patagonia
(Asociación Argentina de Sedimentología, 2019-05)
Despite their geodynamic significance, the stratigraphy and paleoenvironments of the lower-middle Miocene clastic deposits, genetically related to subductiondriven lithospheric processes at the latitude of the Chile Triple ...
