Cretaceous intraplate contraction in Southern Patagonia: A far-field response to changing subduction dynamics?
(American Geophysical Union, 2018-08-13)
The origin, extent, and timing of intraplate contraction in Patagonia are among the least understood geological processes of southern South America. Particularly, the intraplate Deseado fold-thrust belt (FTB), located in ...
Spatio-temporal variation of the strain field in the southern Central Andes broken-foreland (27 degrees 30 ' S) during the Late Cenozoic
(Elsevier BV, 2021-03)
We present an integrated structural and Anisotropy of Magnetic Susceptibility (AMS) study focused on the characterization of the spatio-temporal variation of the strain field during the main Neogene deformation, of the ...
Geochemistry of heavy minerals and U-Pb detrital zircon geochronology in the manantiales basin: implications for Frontal Cordillera uplift and foreland basin connectivity in the Andes of central Argentina
(Elsevier, 2018)
The Manantiales Foreland Basin, located at similar to 32 degrees 15'S in the Frontal Cordillera, Argentina, contains the sedimentary record of erosion of igneous basement and Miocene volcanic rocks exhumed during the Andean ...
The Neuquén group: The reconstruction of a Late Cretaceous foreland basin in the southern Central Andes (35–37°S)
(Elsevier Science, 2019-09)
In the southern Central Andes of Argentina, between 34° and 41°S, the Neuquén Group records Upper Cretaceous nonmarine deposits that provide direct evidence of synorogenic sedimentation associated with the development of ...
Comparative structural analysis of inverted structures in the San Bernardo fold belt (Golfo San Jorge basin, Argentina): Inversion controls and tecto-sedimentary context of the Chubut Group
(Pergamon-Elsevier Science Ltd, 2020-01)
The Golfo San Jorge Basin is one of the most important hydrocarbon-bearing basins of Argentina. Its position in the distal Patagonian Broken Foreland confers a particular structural architecture. Specifically, the western ...
Tectonostratigraphic evolution and timing deformation in the Miocene Paso del Sapo Basin: Implications for the Patagonian broken foreland
(Pergamon-Elsevier Science Ltd, 2019-10)
Several segments of the Central and Southern Andes show deformation evidences located far away from the orogenic front. As a result, a landscape constituted by fault-blocks mountains and intermontane basins occurs. The ...
Neotectonic Activity in the Low-Strain Broken Foreland (Santa Bárbara System) of the North-Western Argentinean Andes (26_S)
(Geoscienceworld, 2020-10)
Uplift in the broken Andean foreland of the Argentine Santa Bárbara System (SBS) is associated with the contractional reactivation of basement anisotropies, similar to those reported from the thick-skinned Cretaceous-Eocene ...
Alluvial to lacustrine sedimentation in an endorheic basin during the Mio-Pliocene: The Toro Negro Formation, Central Andes of Argentina
(Pergamon-Elsevier Science Ltd, 2018-07)
A 2400 m-thick sedimentary column belonging to the Toro Negro Formation was recorded along the Quebrada del Yeso, Sierra de Los Colorados (Vinchina Basin), La Rioja province, NW Argentina. The Vinchina basin is a good ...
Geochemistry of heavy minerals and U–Pb detrital zircon geochronology in the Manantiales Basin: Implications for Frontal Cordillera uplift and foreland basin connectivity in the Andes of central Argentina
(Elsevier Science, 2018-03)
The Manantiales Foreland Basin, located at ~ 32°15′S in the Frontal Cordillera, Argentina, contains the sedimentary record of erosion of igneous basement and Miocene volcanic rocks exhumed during the Andean orogeny. U–Pb ...
Relleno intermontano en el Antepaís Fragmentado Patagónico: evolución neógena de la Cuenca de GastreIntermontane infill in the patagonian broken foreland: Neogene evolution of the Gastre Basin
(Asociación Geológica Argentina, 2014-06)
La Cuenca de Gastre ubicada a centenares de kilómetros del margen de subducción, constituye una de las mayores cuencas intermontanas desarrolladas dentro del antepaís fragmentado patagónico. Su origen en el Mioceno medio ...
