The influence of variations in crustal composition and lithospheric strength on the evolution of deformation processes in the southern Central Andes: insights from geodynamic models
(Springer, 2021-02)
Deformation in the orogen-foreland system of the southern Central Andes between 33° and 36° S varies in style, locus, and amount of shortening. The controls that determine these spatially variable characteristics have ...
Oliine-induced iscous anisotropy in fossil strike-slip mantle shear zones and associated strain localization in the crust
(Wiley Blackwell Publishing, Inc, 2021-01)
We propose that strain localization in plate interiors, such as linear belts of intraplate seismicity, may arise from spatial ariations in iscous anisotropy produced by preferred orientation of oliine crystals (CPO or ...
3D data-derived lithospheric structure of the Central Andes and its implications for deformation: Insights from gravity and geodynamic modelling
(Elsevier Science, 2019-07)
We present a new three-dimensional density model of the CentralAndes characterizing the structure and composition of the lithospheretogether with a geodynamic simulation subjected to continental intraplateshortening. The ...
Arcabouço geofísico, isostasia e causas do magmatismo cenozóico da província Borborema e de sua margem continental (Nordeste do Brasil)
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2008-07-27)
The Borborema Province (BP) is a geologic domain located in Northeastern Brazil. The BP is limited at the south by the São Francisco craton, at the west by the Parnaíba basin, and both at the north and east by coastal ...
Cenozoic intraplate tectonics in Central Patagonia: Record of main Andean phases in a weak upper plate
(2017)
Contraction in intraplate areas is still poorly understood relative to similar deformation at plate margins. In order to contribute to its comprehension, we study the Patagonian broken foreland (PBF) in South America whose ...
The thermo-mechanical state of the Andes in the Altiplano-Puna region: insights from Curie isotherm and effective elastic thickness determinationEl estado termo-mecánico de los Andes en la región del Altiplano-Puna a partir del cálculo de la profundidad de Curie y el espesor elástico
(Asociación Geológica Argentina, 2019-10)
Presentamos nuevos resultados de la distribución de temperatura en la corteza en la región del Atiplano-Puna y un nuevo modelo de espesor elástico para los Andes Centrales. El objetivo de este trabajo es determinar el ...
Cenozoic intraplate tectonics in Central Patagonia: Record of main Andean phases in a weak upper plate
(Elsevier Science, 2017-11)
Contraction in intraplate areas is still poorly understood relative to similar deformation at plate margins. In order to contribute to its comprehension, we study the Patagonian broken foreland (PBF) in South America whose ...
New insights into the Andean crustal structure between 32° and 34°S from GOCE satellite gravity data and EGM2008 model
(Geological Society of London, 2014-02)
The subduction of the Nazca oceanic plate under the South American plate in the southcentral Andes region is characterized by the oblique collision of the Juan Fernandez Ridge against the continental margin. The upper plate ...
Tectonic inheritance and structural styles in the Andean fold-thrust belt and foreland basin
(Elsevier, 2022)
Andean orogenesis is expressed in the diverse deformational records of crustal structures and sedimentary basins in western South America. Here we summarize retroarc structural styles within the Andean orogenic belt and ...
