The Cerro Aguas Calientes caldera, NW Argentina: An example of a tectonically controlled, polygenetic collapse caldera, and its regional significance
(Elsevier Science, 2010-07)
Polygenetic, silicic collapse calderas are common in the central Andes. Here we describe in detail the Cerro Aguas Calientes caldera in NW Argentina, which comprises two caldera-forming episodes that occurred at 17.15. Ma ...
Crustal collapse in the Andean backarc since 2 Ma: Tromen volcanic plateau, Southern Central Andes (36°40′-37°30′S)
(Elsevier Science, 2008-11)
Analysis of seismic lines and gravity data shows the existence of Quaternary extensional depocenters beneath thick covers of < 1 Ma-old volcanic rocks in the Tromen volcanic plateau backarc region (36°40′-37°30′S). Dating ...
Extensional tectonics and gravitational collapse in an Ordovician passive margin: The Western Argentine Precordillera
(Elsevier Science, 2008-03)
The paper describes ubiquitous extensional structures developed in a passive margin of Ordovician age in the Argentine Precordillera. These extensional structures include normal faults and boudinaged sequences. In some ...
Miocene to Recent collapse calderas of the southern and central volcanic zones of the Andes and their tectonic constraints
(Springer, 2021-01-30)
Central (18–28° S) and Southern (33–46° S) Andean Volcanic Zones (CVZ and SVZ, respectively) have several Miocene to Recent collapse calderas. We compare their characteristics based on published data to identify how the ...
Gravity collapse structures in the Central Precordillera fold-and-thrust belt, Argentina
(Universidad Complutense de Madrid. Facultad de Ciencias Geológicas. Departamento de Estratigrafía, 2016-08)
Numerosas formas de relieve ubicadas en el área de la faja plegada y corrida de la Precordillera Central de Argentina, que a menudo se asocian con una tectónica compresiva, están de hecho relacionadas con procesos ...
Volcanotectonics: the tectonics and physics of volcanoes and their eruption mechanics
(2022)
The physical processes that operate within, and beneath, a volcano control the frequency, duration, location and size of volcanic eruptions. Volcanotectonics focuses on such processes, combining techniques, data, and ideas ...
The Luingo caldera: The south-easternmost collapse caldera in the Altiplano–Puna plateau, NW Argentina
(Elsevier Science, 2010-07)
This article identifies the Pucarilla–Cerro Tipillas Volcanic Complex and its major eruptive source, the Luingo caldera (26° 10′S–66° 40′W). Detailed geological mapping, stratigraphic sections, facies analysis and correlations, ...
Geodynamic evolution of the SW Variscides: Orogenic collapse shown by new tectonometamorphic and isotopic data from western Ossa-Morena Zone, SW Iberia
(AMER GEOPHYSICAL UNION, 2008)
The pre-Mesozoic geodynamic evolution of SW Iberia has been investigated on the basis of detailed structural analysis, isotope dating, and petrologic study of high-pressure (HP) rocks, revealing the superposition of several ...
Structure and tectonics of the central Chilean margin (31 degrees-33 degrees S): implications for subduction erosion and shallow crustal seismicity
(Oxford University Press, 2015)
The pre- and current collision of the Juan Fernandez Ridge with the central Chilean margin at 31 degrees-33 degrees S is characterized by large-scale crustal thinning and long-term subsidence of the submarine forearc caused ...
El Morro caldera (33° 10′ S, 66° 24′ W), San Luis, Argentina: An exceptional case of fossil pre-collapse updoming
(Elsevier Science, 2017-03)
Volcanism at Sierra del Morro represents the final stages of the flat-slab related magmatism in the easternmost San Luis Neogene Volcanic Belt. This ~80 km-long NW-WNW-trending belt tracks the episodic inland migration of ...
