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)
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 ...
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 ...
Basic magmatism in northeastern Puna, Argentina: Chemical composition and tectonic setting in the Ordovician back-arc
(Pergamon-Elsevier Science Ltd, 2009-12)
Two main groups of basic rocks, representative of the bimodal Ordovician magmatism of the northeastern Puna (22-24°S, 66°30'-65°40'W) were revisited on the basis of new geological, petrographic and geochemical data. One ...
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 ...
Geochemical variations in Cenozoic back-arc basalts at the border of La Pampa and Mendoza provinces, Argentina
(Pergamon-Elsevier Science Ltd, 2009-12)
Back-arc volcanism was active in central-western Argentina (provinces of Mendoza and La Pampa) from the Miocene through historic times. The rocks of 39 monogenetic volcanoes located in this area were studied in order to ...
