The origin of the Loncopué Trough in the retroarc of the Southern Central Andes from field, geophysical and geochemical data
(Elsevier Science, 2014-12)
This work analyzes through field, geophysical, geochemical and geochronological data, a particular setting of the Southern Andes in which an extensional system is flanking the mountain front. This setting is represented ...
Alternating contraction and extension in the southern central andes (35°-37°s)
(Amer Journal Science, 2019-05)
The Andes are thought to be formed through discrete contractional stages separated by periods of little to no orogenic construction. This paper analyzes the intervals between the main contractional phases that built the ...
Andean magmatism: its paleogeographic and structural setting in the central part (30-35s) of the southern andes.
(1974)
La parte central de los Andes del Sur (entre las latitudes 30° y 35° S) revela relaciones temporales y espaciales entre el magmatismo y la paleogeográfica y tectónica evolución durante el Ciclo Orogénico Andino ...
Retroarc basin reorganization and aridification during Paleogene uplift of the southern central Andes
(American Geophysical Union, 2017-03)
Tectonic development of the Andean Cordillera has profoundly changed the topography, climate, and vegetation patterns of the southern central Andes. The Cenozoic Bermejo Basin in Argentina (~30°S) provides a key record of ...
Structure and development of the Andean system between 36◦ and 39◦S
(Elsevier, 2014-01)
One of the main morphological changes along the Southern Central Andes occurs from 36° to 39°S. The northern portion is characterized by prominent basement structures and a thick-skinned orogenic front with relief of over ...
The Southern Central Andes vertical axis tectonic rotations: relations with the deformation patternRotaciones tectónicas según ejes verticales en los Andes Centrales del Sur: relaciones con el patrón de deformación
(Servicio Nacional de Geología y Minería, 2012-05)
En los Andes Centrales se ha identificado un patrón de rotaciones tectónicas según ejes verticales a través de estudios paleomagnéticos. Dichas rotaciones son en sentido antihorario al norte del codo de Arica (~19°S) y en ...
Permian to Triassic extensional deformation superimposed to Gondwanic structures in the cordillera del Viento (Southern Central Andes): A combined field and geophysical study
(Universidad Complutense de Madrid, 2014-06)
Combined field and gravimetric-magnetic data reveal a complex pattern of extensional structures superimposed to the late Carboniferous – Early Permian Gondwanan orogen at the inner sectors of the Southern Central Andes, ...
Remarkable variability in dyke features at the Vicuña Pampa Volcanic Complex, Southern Central Andes
(Wiley Blackwell Publishing, Inc, 2017-08)
Dykes at the Vicuña Pampa Volcanic Complex, which are mostly basaltic (trachy)-andesite and (trachy)-andesite, are exposed at the base and along the walls of a large depression resulting from intense degradation. Dykes ...
