Sr–Nd isotope data of basement rocks from the northernmost argentine Precordillera and its implications for the early Paleozoic evolution of SW Gondwana margin
(Pergamon-Elsevier Science Ltd., 2014-08)
The Precordillera terrane (Cuyania) in western Argentina is commonly accepted as an exotic fragmentderived from Laurentia in the Early Paleozoic. Evidence supporting such an interpretation is manly basedon similarities in ...
Detrital chromian spinels from Upper Ordovician deposits in the Precordillera terrane, Argentina: A mafic crust input
(Pergamon-Elsevier Science Ltd, 2009-12)
The study of heavy minerals from the Caradocian Pavón Formation (central Argentina) suggests that MORB and continental intraplate flood basalts were among the source rocks for the detrital record. The Pavón Formation was ...
Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane
(Geological Society of America, 2015-10)
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand ...
Subgreenschist facies metamorphism of metabasites from the Precordillera terrane of western Argentina; constraints on the later stages of accretion onto Gondwana
(E Schweizerbartsche Verlags, 2005-05)
The metamorphic character of metabasites of the Precordillera terrane of western Argentina provides constraints which help to distinguish between contrasting models for the tectonic settings during the late stages of the ...
Linguliformean Brachiopods from the Las Plantas Formation (Ordovician, Sandbian), Argentine Precordillera
(Asociación Paleontológica Argentina, 2018-06)
This paper is a brief contribution to the taxonomy of the still poorly known Ordovician lingulate brachiopods of Argentina. A linguliform brachiopod fauna from the Las Plantas Formation (Sandbian, Ordovician) in the northern ...
Structural evolution of a composite middle to lower crustal section: The Sierra de Pie de Palo, northwest Argentina
(American Geophysical Union, 2011-02)
The Sierra de Pie de Palo of northwest Argentina preserves middle to lower crustal metamorphic rocks that were penetratively deformed during Ordovician accretion of the Precordillera terrane to the Gondwana margin. New ...
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 ...
Lower and middle cambrian rhynchonelliform brachiopods from the precordillera terrane of Argentina
(Paleontological Society, 2012-03)
The first Cambrian rhynchonelliformean brachiopods are described from the Precordillera mountain belt of west-central Argentina, including the new species Wimanella mollensis and Nisusia ancauchensis. Other forms are ...
