Volcanic stratigraphy and evidence of magma mixing in the Quaternary Payún Matrú volcano, andean backarc in western Argentina
(Servicio Nacional de Geología y Minería, 2012)
Vent distribution in the Quaternary Payún Matrú Volcanic Field, western Argentina: Its relation to tectonics and crustal structures
(Elsevier Science, 2014-05)
The Payún Matrú Volcanic Field consists of two polygenetic and mostly trachytic volcanoes (Payún Matrú with a summit caldera and Payún Liso) along with around 220 scoria cones and basaltic lava flows. This volcanic field ...
Volcanic evolution of the back-arc Pleistocene Payun Matru volcanic field (Argentina)
(Pergamon-Elsevier Science Ltd, 2010-04)
For the first time, about 30 volcanic formations of the back-arc Payun Matru volcanic field (Payun Matru volcanic field, Argentina, 36°S, 69°W) have been sampled for K-Ar geochronology and geochemistry in order to reconstruct ...
The role of magma mixing and mafic recharge in the evolution of a back-arc quaternary caldera: The case of Payún Matrú, Western Argentina
(Elsevier Science, 2016-02)
The Quaternary Payún Matrú volcano is a long-lived edifice that developed a summit caldera 8 km wide, with abundant pre- and post-caldera volcanic activity. It is the main volcano of the Payún Matrú Volcanic Field, which ...
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 ...
Post-caldera pumice cones of the Payún Matrú caldera, Payenia, Argentina: Morphology and deposits characteristics
(Pergamon-Elsevier Science Ltd, 2019-03)
The formation of pumice cones by deposition of near-vent pumice fragments is relatively rare in comparison with the occurrence of their mafic equivalents, the scoria cones. The Quaternary Payún Matrú caldera (36° S, 69° ...
