Provenance and Evolution of the Guarguaráz Complex, Cordillera Frontal, Argentina
(Elsevier Science, 2004-10)
The Guarguaráz Complex, basement of the Cordillera Frontal, included in the proposed Chilenia Terrane, consists of metasedimentary rocks deposited in clastic and carbonatic platforms. Turbiditic sequences point out to slope ...
P-T evolution of metapelites from the Guarguaraz Complex, Argentina: evidence for Devonian crustal thickening close to the western Gondwana margin
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)
In the Guarguaraz Complex of the Argentine Frontal Cordillera (latitude 33.3°S) serpentinite lenses,
metabasites, and garnet-bearing metasedimentary rocks occur. The corresponding Devonian metamorphic event was
assigned ...
The Guarguaraz Complex and the Neoproterozoic-Cambrian evolution of southwestern Gondwana: Geochemical signatures and geochronological constraints
(Pergamon-Elsevier Science Ltd, 2009-12)
The Guarguaraz Complex, in western Argentina, comprises a metasedimentary assemblage, associated with mafic sills and ultramafic bodies intruded by basaltic dikes, which are interpreted as Ordovician dismembered ophiolites. ...

The Guarguaraz Complex and the Neoproterozoic-Cambrian evolution of southwestern Gondwana: Geochemical signatures and geochronological constraints
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
The Guarguaraz Complex, in western Argentina, comprises a metasedimentary assemblage, associated with mafic sills and ultramafic bodies intruded by basaltic dikes, which are interpreted as Ordovician dismembered ophiolites. ...
The geodynamics of collision of a microplate (Chilenia) in Devonian times deduced by the pressure-temperature-time evolution within part of a collisional belt (Guarguaraz Complex, W-Argentina)
(Springer, 2011-08)
The Guarguaraz Complex in West Argentina formed during collision between the microplate Chilenia and South America. It is composed of neritic clastic metasediments with intercalations of metabasic and ultrabasic rocks of ...
Metasomatismo en ortoanfibolitas de la Faja Máfica-Ultramáfica del Río de Las Tunas, MendozaMetasomatism in orthoamphibolites from the Río de Las Tunas mafic-ultramafic belt, Mendoza
(Asociación Geológica Argentina, 2012-04)
Se identificaron claras evidencias petro-mineralógicas y químicas de metasomatismo en ortoanfibolitas de la faja máficaultramáfica del Río de Las Tunas, Cordillera Frontal de Mendoza. Estas ortoanfibolitas integran el ...
High-pressure/low-temperature metamorphism in the collision zone between the Chilenia and Cuyania microcontinents (western Precordillera, Argentina)
(Pergamon-Elsevier Science Ltd, 2016-12)
In central-western Argentina, an Early Paleozoic belt including mafic-ultramafic bodies, marine metasedimentary rocks and high-pressure rocks occur along the western margin of the Precordillera and in the Frontal Cordillera. ...
Provenance of the Miocene Alto Tunuyan Basin (33 degrees 40 ' S, Argentina) and its implications for the evolution of the Andean Range: Insights from petrography and U-Pb LA-ICPMS zircon ages
(Elsevier, 2016)
The Alto Tunuyan Foreland Basin in western Argentina is located immediately south of the flat-slab segment of the Central Andes and its evolution is directly related to the propagation of structures to the east. Petrographic ...
