Neogene Patagonian magmatism between the rupture of the Farallon plate and the Chile Ridge subduction
(2021)
Based on chemical composition and timing of late Paleogene and Neogene igneous rocks in southern Patagonia, six igneous suites are identified and correlated with subduction processes during the approaching and subduction ...
Magmatism as a probe to the neogene shallowing of the nazca plate beneath the modern chilean flat-slab
(PERGAMON-ELSEVIER SCIENCE LTD,, 2002)
Neogene Patagonian magmatism between the rupture of the Farallon plate and the Chile Ridge subduction
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-10)
Based on chemical composition and timing of late Paleogene and Neogene igneous rocks in southern Patagonia, six igneous suites are identified and correlated with subduction processes during the approaching and subduction ...
The relationship between Cenozoic shallow igneous bodies and thrust systems of the mountain front of the Cordillera Principal, Mendoza province, Argentina
(Pergamon-Elsevier Science Ltd, 2019-03-30)
Within the Malargüe fold and thrust belt, located in the southern Central Andes, south of Mendoza province, Argentina, several shallow intrusive bodies which are part of extensive Neogene magmatism are exposed and linked ...
Neogene retroarc foreland basin evolution, sediment provenance, and magmatism in response to flat slab subduction, western Argentina
(American Geophysical Union, 2020-05)
Understanding the effects of flat slab subduction on mountain building, arc magmatism, and basin evolution is fundamental to convergent-margin tectonics, with implications for potential feedbacks among geodynamic, magmatic, ...
Fault-related folding, drainage network evolution and valley incision during the Neogene in the Andean Precordillera of Northern Chile
(ELSEVIER, 2005-02-15)
We describe Neogene drainage network development before, during and after regional folding in the Precordillera of the Andes of Northern Chile (18degrees-19degreesS). The drainage network developed on an extensive regular ...
Southern central andes neogene magmatism over the pampean flat slab: Implications on crustal and slab melts contribution to magma generation in Precordillera, Western ArgentinaMagmatismo neógeno en la sección sur de los Andes centrales sobre la zona de subducción horizontal pampeana: Implicancias respecto de las contribuciones de los fundidos corticales y de la placa subductada en la generación de magmas en precordillera, Argentina
(Servicio Nacional de Geología y Minería, 2017-09)
A Miocene to Pliocene (13 to 4.6 Ma) mostly pyroclastic sequence is exposed along the Iglesia Valley, to the east of the former main volcanic arc. This area is a transitional region between Cordillera Frontal and Precordillera, ...
The Cerro Bitiche Andesitic Field: petrological diversity and implications for magmatic evolution of mafic volcanic centers from the northern Puna
(Springer, 2016-06)
The Cerro Bitiche Andesitic Field (CBAF) is one of the two largest mafic volcanic fields in northern Puna (22–24° S) and is spatially and temporally associated with ignimbrites erupted from some central Andean Altiplano-Puna ...
Neogene activity of the Barrancas Bancas Fault and its relationship with Hydrothermal and volcanic activity
(8th International Symposium on Andean Geodynamics (ISAG)EC, 2019-09)
The chronology and nature of the Neogene-Cuaternary deformation in the Central Volcanic Zone (CVZ) in the north of Chile is partially unclear. Some authors have identified compression in isolated areas of the western slopes ...
