Geophysical perspective on the structural interference zone along the Neoproterozoic Brasília and Ribeira fold belts in West Gondwana
(2017-03-01)
The Brasília and Ribeira fold belts have been established in south-southwestern São Francisco Craton during the Brasiliano-Pan African orogeny (0.9-0.5 Ga - Tonian to Cambrian), and played an important role in West Gondwana ...
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 ...
Andean evolution at the Guañacos and Chos Malal fold and thrust belts (36°30′-37°s)
(Pergamon-Elsevier Science Ltd, 2007-10)
The Andes between 36°30′ and 37°S represent a Cretaceous fold and thrust belt strongly reactivated in the late Miocene. Most of the features that absorbed Neogene shortening were already uplifted in the late Cretaceous, ...
Tectonic repetitions of the Early Cretaceous Agrio Formation in the Chos Malal fold-and-thrust belt, Neuquén Basin, Argentina: Geometry,kinematics and structural implications for Andean building
(Elsevier, 2014-04)
The Neuquén Basin, developed in a retroarc setting in the central-west of Argentina, contains more than 6000 m of Mesozoic marine and continental sedimentary rocks. These rocks were deformed during the Andean orogeny leading ...
Structural evolution of the Andes in a transitional zone between flat and normal subduction (33°30′-33°45′S), Argentina and Chile
(Pergamon-Elsevier Science Ltd, 2002)
The closure of the Rocas Verdes Basin and early tectono-metamorphic evolution of the Magallanes Fold-and-Thrust Belt, southern Patagonian Andes (52–54°S)
(Elsevier Science, 2021-01)
The Western Domain of the Magallanes Fold-and-Thrust Belt (MFTB) between 52°-54°S is part of a poorly studied hinterland region of the southernmost Andean Cordillera. This domain consists of NNW-SSE trending tectonic slices ...
Kinematics of a backthrust system in the Agrio fold and thrust belt, Argentina: Insights from structural analysis and analogue models
(Pergamon-Elsevier Science Ltd, 2020-04-07)
The Agrio fold and thrust belt is an orogenic belt located in the Southern Central Andes (37°-38°S latitude). A setof thin-skinned thrust-related folds with opposite vergence to the tectonic push, occur in front of major ...
Igneous petroleum systems in the Malargüe fold and thrust belt, Río Grande Valley area, Neuquén Basin, Argentina
(Elsevier, 2020-01)
The Río Grande Valley (Neuquén Basin, Argentina) is a large oil field where voluminous igneous sill complexes are emplaced in different levels of the sedimentary sequence in a fold and thrust belt setting. These sills are ...
Proveniência e idade do metamorfismo das rochas da faixa Brasilia, na região de tapira (SW de Minas Gerais)
(2006-07-01)
The Brasilia Fold Thrust Belt at Tapira area (SW of Minas Gerais State, Brazil) has four different litho-tectonic domains imbricated by thrust faults with vergency to the São Francisco Craton. Sm/Nd isotopic studies were ...
