GOCE satellite derived gravity and gravity gradient corrected for topographic effect in the South Central Andes region
TL;DR: In this paper, the Earth gravity model EGM08 was used to calculate two functionals of the geopotential: the gravity anomaly and the vertical gravity gradient applied to the South Central Andes area.

GOCE derived vertical gravity gradient delineates great earthquake rupture zones along the Chilean margin
Orlando Álvarez,Orlando Álvarez,Silvina Nacif,Mario Gimenez,Mario Gimenez,Andrés Folguera,Andrés Folguera,Carla Braitenberg +7 more
TL;DR: In this article, the authors calculated the topography corrected vertical gravity gradient from GOCE satellite data and from EGM2008 model in order to delineate mass heterogeneities related to density variations along the south-central Chile subduction zone.

Late Oligocene–early Miocene submarine volcanism and deep-marine sedimentation in an extensional basin of southern Chile: Implications for the tectonic development of the North Patagonian Andes

TL;DR: The Traiguen Formation of the Andean Cordillera has been used as the model of an ocean-continent convergent system dominated by compression and active mountain building as a consequence of the strong mechanical coupling between the upper and lower plates.

TL;DR: A broad range of processes acted simultaneously during the Quaternary producing relief in the Andes and adjacent foreland, from the Chilean coast, where the Pacific Ocean floor is being subducted beneath South American, to the Brazilian and the Argentinean Atlantic platform area as discussed by the authors.

New evidence about the subduction of the Copiapó ridge beneath South America, and its connection with the Chilean-Pampean flat slab, tracked by satellite GOCE and EGM2008 models
Orlando Álvarez,Orlando Álvarez,Mario Gimenez,Mario Gimenez,Andrés Folguera,Andrés Folguera,Silvana Spagnotto,Silvana Spagnotto,Emilce Bustos,Walter Ariel Baez,Carla Braitenberg +10 more
TL;DR: In this paper, Alvarez Pontoriero et al. presented a study of the relationship between geofisico sismologico Volponi (GSV) and Argentina.
