Facies distribution as a response to early rift tectonic activity in the Sergipe-Alagoas Basin, northeastern Brazil
(Elsevier B.V., 2019-04-01)
Accommodation rates in rift basins are mainly controlled by tectonics. However, during early rift stages, normal fault activity is dispersed and incipient, which makes it difficult to recognize the effects of early crustal ...
Ages of pre-rift basement and synrift rocks along the conjugate rift and transform margins of the Argentine Precordillera and Laurentia
(Geological Society of America, 2012-10)
New geochronologic data from basement rocks support the interpretation that the Argentine Precordillera (Cuyania) terrane was rifted from the Ouachita embayment of the Iapetan margin of Laurentia. New data from the Ozark ...
Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model
(Wiley Blackwell Publishing, Inc, 2018-02)
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary ...
Anatomy and Sequence Architecture of the early Post-Rift in the Neuquén Basin (Argentina): A Response to Physiography and Relative Sea-level Changes
(Society for Sedimentary Geology, 2013-08)
A detailed architectural and sequence stratigraphic analysis was carried out in the early-post-rift succession of central Neuque´n Basin (Middle Jurassic Cuyo Group), integrating outcrop and subsurface information from a ...
Mafic dykes at the southwestern margin of Eastern Ghats belt: Evidence of rifting and collision
(INDIAN ACAD SCIENCES, 2010)
The southwestern margin of the Eastern Ghats Belt characteristically exposes mafic dykes intruding massif-type charnockites. Dykes of olivine basalt of alkaline composition have characteristic trace element signatures ...
Alluvial fan deposition along a rift depocentre border from the Neuquén Basin, Argentina
(Elsevier Science, 2014-03)
The interaction between hangingwall block rotation and alluvial deposition is examined from Late Triassic–Early Jurassic successions exposed along the Catán Lil half-graben border fault system in the Neuquén Basin, Argentina. ...
New insights of the tectonic and sedimentary evolution of the Rio Grande Rise, South Atlantic Ocean
(2019-12-01)
Oceanic plateaus, such as the Rio Grande Rise (RGR), comprise crucial pieces of information about the opening of the South Atlantic Ocean and the evolution of associated lithospheric plate margins. A detailed seismostratigraphic ...
Estratigrafía de 'sin-rift' (Triásico Superior-Jurásico Inferior) de la Cuenca Neuquina en la sierra de Chacaico, Neuquén, Argentina
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2007)
Transtensional tectonics induced by oblique reactivation of previous lithospheric anisotropies during the Late Triassic to Early Jurassic rifting in the Neuquén basin: Insights from analog models
(Pergamon-Elsevier Science Ltd, 2014-09)
The goal of this study was to determine the main factors that controlled the kinematic evolution and the structural architecture developed during the Late Triassic to Early Jurassic rifting that led to the opening of the ...
