Early Devonian trilobites from the Sierra de Las Minitas, northernmost Precordillera (La Rioja province), Argentina
(Asociacion Paleontologica Argentina, 2011-06)
Early Devonian trilobites are described based on material from Sierra de Las Minitas, in the northern extent of the Precordillera, western Argentina. This diverse fauna, the first one known from La Rioja Province, includes ...
Upper Cambrian carbonate sequences of the Argentine Precordillera and the Steptoean C-Isotope positive excursion (SPICE)
(ELSEVIER SCIENCE BV, 2008-07)
Carbon and Sr-isotope profiles in Upper Cambrian platformal carbonate Formations in the Precordillera, western Argentina (Zonda, La Flecha
and La Silla Formations), were constructed for three representative sections: (a) ...
A Silurian - Devonian marine platform-deltaic system in the San Rafael Block, Argentine Precordillera-Cuyania terrane: Lithofacies and provenance
(Geological Society Publications House, 2009-05)
The San Rafael Block is included as a part of the pre-Andean region, in the southern sector of the Argentine Precordillera-Cuyania terrane, within the western Gondwana margin. The Río Seco de los Castaños Formation (Upper ...
Reconstrucción estructural de una sección de la Precordillera Occidental Argentina (31º08’ls-69º24’lo) a partir de datos aeromagnéticos
(European Association of Geoscientists & Engineers, 2015-03)
The magnetic anomaly profile performed along the NE-SW (31º08’LS - 69º24’LO) structural section at the western edge of the Argentine Precordillera, is presented. By the application of ratios between bands, Landsat 7 ETM+ ...
The mafic-ultramafic belt of the Argentine Precordillera: A geological synthesis
(Pergamon-Elsevier Science Ltd, 2021-10)
In central-western Argentina, a mafic-ultramafic belt occurs throughout the western margin of the Precordillera. This belt is interpreted as the suture zone between the Cuyania terrane and the Chilenia terrane, both accreted ...
The Cuyano proto-ocean between the Chilenia and Cuyania terranes: Rifting and plume interaction during the Neoproterozoic - Early Palaeozoic evolution of the SW Gondwana margin
(Cambridge University Press, 2021-03)
The Precordillera mafic–ultramafic belt (PMUB), located in central-western Argentina, comprises mafic and ultramafic bodies interlayered and/or in tectonic contact with marine siliciclastic units. Whole-rock, mineral ...
Geological and geophysical evidences of the polyphase structural evolution of the Southern Precordillera (31°42′S-69°24′W), central-western Argentina
(Pergamon-Elsevier Science Ltd, 2018-11)
The evolution of the western margin of South America comprised different tectonic regimes responsible of the present geological composition and structure of the Central Andes. Remote sensing, geological and geophysical ...
New insights on Lower Ordovician (Floian) reefs from the Argentine Precordillera: Biostratigraphic, sedimentologic and paleogeographic implications
(Pergamon-Elsevier Science Ltd, 2020-11)
The shallow carbonate facies of the middle part from the San Juan Formation that outcrops in the Central Precordillera is studied in the present contribution in order to assess conodont biostratigraphy and sedimentology. ...
The conodont Paroistodus horridus (Barnes and Poplawski) as a new biostratigraphical tool for the middle Darriwilian (Ordovician)
(Elsevier Science, 2020-07-01)
This contribution develops an analysis on the conodont Paroistodus horridus (Barnes and Poplawski) from several Argentine Precordilleran sections. From these collections, we have established that P. horridus occurs from ...
The Late Neoproterozoic-Early Paleozoic basin of the western Argentine Precordillera: Insights from zircon U-Pb geochronology
(Pergamon-Elsevier Science Ltd, 2020-10)
In central-western Argentina, a belt including marine metasedimentary rocks and mafic-ultramafic bodies occurs throughout the western margin of the Precordillera. The belt is considered as the suture zone between the poorly ...
