An Andean tectonic cycle: From crustal thickening to extension in a thin crust (34°-37°SL)
(Elsevier Science, 2014-01)
Several orogenic cycles of mountain building and subsequent collapse associated with periods of shallowing and steepening of subduction zones have been recognized in recent years in the Andes. Most of them are characterized ...
Ages and geochemistry of Mesozoic-Eocene back-arc volcanic rocks in the Aysén region of the Patagonian Andes, Chile
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2001)
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 ...
Estrutura crustal da Bacia do Recôncavo-Tucano com inversão simultânea de dados sismológicos
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2021-07-30)
The stresses that led to the opening of the South Atlantic were responsible for
intracontinental extensions and, consequently, for the formation of a number of aborted
rifts in Northeastern Brazil. The extension began in ...
Crustal deformation across the Southern Patagonian Icefield observed by GNSS
(Elsevier Science, 2016-10)
Geodetic GNSS observations at 43 sites well distributed over the Southern Patagonian Icefield region yield site velocities with a mean accuracy of 1 mm/a and 6 mm/a for the horizontal and vertical components, respectively. ...
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 ...
