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 ...
Deformational evolution of a Cretaceous subduction complex: Elephant Island, South Shetland Islands, Antarctica
(Elsevier B.V., 2000-03-30)
New structural data from Elephant Island and adjacent islands are presented with the objective to improve the understanding of subduction kinematics in the area northeast of the Antarctic Peninsula. on the island, a first ...

Seismic velocity structure in the area of the 2007, Mw 8.0, Pisco-Peru earthquake: implications for the mechanics of subduction in the vicinity of the Nazca ridge
(Hindawi, 2020-11-06)
In this study, we present a velocity model for the area of the 2007 Pisco-Peru earthquake (Mw = 8.0) obtained using a double-difference tomography algorithm that considers aftershocks acquired for 6 months. The studied ...
Dots-and-Lines Approach to Subduction Volcanism and Tectonics「点と線」に注目した沈み込み帯の火山とテクトニクス
(Tokyo Geographical Society, 2017-04)
Anomalous arc volcanoes tend to exist where a linear topographic feature (fracture zone, line of seamounts, or ridge) on the oceanic plate is subducting. “Dots-and-lines tectonics” are proposed for clarifying this tendency ...
Evolution of the upper crustal deformation in subduction zones
(American Society of Mechanical Engineers, 2006-11)
The uplift and evolution of a noncollisional orogen developed along a subduction zone, such as the Andean system, is a direct consequence of the interrelation between plate tectonic stresses and erosion. Tectonic stresses ...
Testing the influence of far-field topographic forcing on subduction initiation at a passive margin
(Amsterdam, 2014-04-10)
Despite favourable gravitational instability and ridge-push, elastic and frictional forces prevent subduction initiation fromarising spontaneously at passive margins. Here,we argue that forces arising fromlarge continental ...
Oligocene to present shallow subduction beneath the southern Puna plateau
(Elsevier Science, 2020-04)
The southern Puna plateau is a conspicuous example of a high-elevation orogenic plateau in a non-collisional setting. This orogenic sector is currently located above an anomalously shallow subduction segment, in which ...
