Late cretaceous to cenozoic deformation and exhumation of the chilean frontal cordillera (28°–29°S), Central Andes
(Elsevier, 2017)
The Frontal Cordillera in northern Chile is located over the flat-slab subduction segment of the Central Andes.
This tectonic province is characterized by a thick-skinned structural style showing evidence of tectonic ...
Stratigraphy and paleogeography of the Eocene in the Mosqueiro Low, Sergipe-Alagoas Basin
(2021-01-01)
The oldest petroleum discoveries on the Brazilian offshore margin are in Paleogene reservoirs of the Guaricema and Dourado fields in the structural Mosqueiro Low, the Southern Sergipe-Alagoas Basin. Study of well logs and ...
Reactivation, inversion and basement faulting and thrusting in the Sierras Pampeanas of Córdoba (Argentina) during Andean flat-slab deformation
(Cambridge University Press, 2016-06)
The Sierras Pampeanas of Córdoba are the easternmost uplifted blocks caused by Andean foreland deformation, over 700 km from the Chile trench. This deformation started at c. 340 Ma through basement faults, thrusts and ...
Geometric and kinematic model for basement-involved backthrusting at Diamante River, southern Andes, Mendoza province, Argentina
(Pergamon-Elsevier Science Ltd, 2005-06)
At the confluence of the Las Aucas stream with the Diamante River (69°30′W Long.; 34°40′S Lat.), kilometer-scale structures affecting basement rocks were surveyed. Andean deformation involved both Cordillera Principal and ...
The Estimated Basement of the Fuegian Andes Mesozoic Stratigraphic Series and tThose Rocks Regarded as Pre-Mesozoic in Age
(Springer, 2019)
The role of the Serie Porfirítica as basement is known, as a consequence of the regional extension of the quartz porphyries in Patagonia. This would be a restricted concept of the word basement. Besides this aspect, it is ...
Structural style of the Malargüe fold-and-thrust belt at the Diamante River area (34°30'-34°50'S) and its linkage with the Cordillera Frontal, Andes of central Argentina
(Pergamon-Elsevier Science Ltd, 2010-04)
The Malargüe fold-and-thrust belt is a thick-skinned belt developed in Miocene-Pliocene times during the Andean orogeny, which together with the Cordillera Frontal constitutes the Andes of central Argentina in the Diamante ...
Basement-involved deformation overprinting thin-skinned deformation in the Pampean flat-slab segment of the southern Central Andes, Argentina
(Cambridge University Press, 2016-09)
In the southern Central Andes, the Andean foreland was deformed due to Neogene shallowing of the Nazca slab beneath the South America plate. In this 27-33° S Pampean flat-slab segment, the N-trending Argentine Precordillera ...
Geometry and kinematics of the Andean thick-skinned thrust systems: Insights from the Chilean Frontal Cordillera (28 degrees-28.5 degrees S), Central Andes
(Elsevier, 2015)
The structure of the Chilean Frontal Cordillera, located over the Central Andes flat-slab subduction segment (27 degrees-28.5 degrees S), is characterized by a thick-skinned deformation, affecting both the pre-rift basement ...
Basement structural control in the Magallanes-Malvinas Fold and Thrust Belt, offshore Argentina
(Pergamon-Elsevier Science Ltd, 2020-11)
In this study, we examine the external part of the Magallanes-Malvinas Fold and Thrust Belt in offshore areas, including a portion in Tierra del Fuego onshore, in southern South America. Our investigations focus on the ...
SHRIMP chronology of the Magallanes Basin basement, Tierra del Fuego: Cambrian plutonism and Permian high-grade metamorphism
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2010)
