Subsurface characterization of quaternary scarps and their possible connection to main structures of the western margin of Precordillera, San Juan, Argentina
(Elsevier Science, 2020-09-05)
The El Tigre fault provides a significant example of Pliocene-Quaternary tectonic activity at the West of Precordillera, receiving considerable attention in the last years. However, longitudinal thrusts of the nearest ...
Ordovician (Floian-lower Darriwilian) conodont biofacies of the San Juan Formation in the Cerro Viejo of Huaco, Argentine Precordillera
(Elsevier Science, 2019-12)
The conodont biofacies from the San Juan Formation at the Cerro Viejo of Huaco, Central Precordillera of Argentina, are analyzed for the identification of faunal dynamics and sea-level changes. The Prioniodus elegans and ...
Structural setting of the Chanic orogen (Upper Devonian) at central-western Argentina from remote sensing and aeromagnetic data. Implications in the evolution of the proto-Pacific margin of Gondwana
(Pergamon-Elsevier Science Ltd, 2018-12)
The basement of the Central Andes located in central-western Argentina (31º20′S - 69º22′W) is composed by the Cuyania and Chilenia terranes which were amalgamated to Gondwana in the Early-Mid Paleozoic. Between the ...
Ordovician metamorphic event in the carbonate platform of the Argentine Precordillera: Implications for the geotectonic evolution of the proto-Andean margin of Gondwana
(Geological Society of America, 2009-12)
An Ordovician metamorphic event is recorded by means of conodont paleothermometry in the slope sedimentary sequences of the Western Precordillera. Allochthonous conodonts from reworked deposits of the eastern carbonate ...
Comparative Lower-Middle Ordovician conodont oxygen isotope palaeothermometry of the Argentine Precordillera and Laurentian margins
(Elsevier Science, 2020-07)
Stratigraphic, palaeontologic, and palaeomagnetic data support a hypothesis that argues for the Argentine Precordillera rifting from the southwestern margin of Laurentia in low latitudes during the Cambrian, migrating ...
Upper Carboniferous retroarc volcanism with submarine and subaerial facies at the western Gondwana margin of Argentina
(Pergamon-Elsevier Science Ltd, 2009-04)
During Late Carboniferous times a continental magmatic arc developed at the western margin of Gondwana in South America, as several marine sedimentary basins were formed at the same time in the retroarc region. North of ...
First late Ordovician paleomagnetic pole for the Cuyania (Precordillera) terrane of western Argentina: A microcontinent or a Laurentian plateau?
(Elsevier Science, 2004-12)
Time and tectonic processes involved in docking of the Argentine Precordillera. (Cuyania terrane) against SW Gondwana has been a matter of much debate. A paleomagnetic study on the Early Caradoc Pavón Formation, exposed ...

(Instituto Geológico y Minero de España, 2014-12)
Se realiza una revisión taxonómica del trilobites corynexochido Clavaspidella digesta de la Precordillera de Mendoza, que es reclasificado como Athabaskia anax especie del Great Basin de Estados Unidos. También se incluyen ...
Quaternary active transpression in the north of Western Precordillera (San Juan and La Rioja, Argentina)
(SCS Publisher, 2011)
We present in this paper some geomorphic, stratigraphic, and structural data indicating neotectonic deformation in the northern Western Precordillera region of San Juan and La Rioja provinces (Argentine Central Andes) which ...
Modelo de sedimentación fluvial y lacustre en el margen pasivo de un hemigraben: el Triásico de la Precordillera occidental de San Juan, República ArgentinaA model for fluvial and lacustrine sedimentation on the passive margin of a half-graben: the Triassic of the western Precordillera of San Juan, Argentine Republic
(Asociación Geológica Argentina, 2001-06)
A model for fluvial and lacustrine sedimentation on the passive margin of a half-graben: the Triassic of the western Precordillera of San Juan, Argentine Republic. Siliciclastic facies and depositional systems are studied ...
