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)
Constraints on the origin and evolution of magmas in the Payún Matrú Volcanic Field, Quaternary andean back-arc of western Argentina
(Oxford University Press, 2013-12-11)
The Payún Matrú Volcanic Field (Pleistocene–Holocene) is located in the Andean back-arc of the Southern Volcanic Zone, western Argentina, and is contemporaneous with the Andean volcanic arc at the same latitude. It includes ...
Change in the pattern of crustal seismicity at the Southern Central Andes from a local seismic network
(Elsevier Science, 2017-06)
Shallow seismicity in the Southern Central Andes is associated with interplate earthquakes due to the subduction of the Nazca plate beneath the South American plate and neotectonic activity, mainly located in the retro-arc ...
Subduction controls on Miocene back-arc lavas from Sierra de Huantraico and La Matancilla and new 40Ar/39Ar dating from the Mendoza Region, Argentina
(Elsevier Science, 2013-10-01)
Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquén has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic ...
The tectonic regime along the Andes: Present-day and Mesozoic regimes
(John Wiley & Sons Ltd, 2010-01)
The analyses of the main parameters controlling the present Chile-type and Marianas-type tectonic settings developed along the eastern Pacific region show four different tectonic regimes: (1) a nearly neutral regime in the ...
The Farallon-Aluk ridge collision with South America: Implications for the geochemical changes of slab window magmas from fore- to back-arc
(Elsevier, 2013-07)
The collision of a divergent ocean ridge may evolve into two end cases: in the continuity of ocean-floor subduction, or in the detachment of the subducted plate. The northern Patagonia active plate margin has the unique ...
Geochronology of the late Pliocene to recent volcanic activity in the Payenia back-arc volcanic province, Mendoza Argentina
(Pergamon-Elsevier Science Ltd, 2012-08)
Eighteen samples originating from monogenetic cones and larger complexes in the back-arc Payenia volcanic province, in Mendoza Argentina, have been dated by the 40Ar/ 39Ar method. Groundmass and plagioclase separates give ...
