Abstract Despite a number of published papers focusing on the geodynamic implications recent Southern Puna mafic magmatism, there have been fewer studies volcanology and stratigraphy this outstanding volcanism. This paper presents detailed map two well-preserved Quaternary scoria cones showing their complex stratigraphy. Complementary morphometric, morpho-structural, petrographic geochemical data were used to reconstruct evolution both volcanoes. The occurrence more than one eruption at each...
Abstract Cordilleran arcs are built by long periods of steady-state magmatism punctuated transient high-flux magmatic episodes or flare-ups. Such flare-ups, manifested as prodigious silicic volcanism and magmatism, result from geodynamic perturbations that cause elevated rates magma addition to the crust. Questions remain, however, about how quantitatively compare between flare-up modes arc after major perturbation begins. Here, we compute new estimates erupted volumes over last 35 Myr for...
This study presents new stratigraphic, structural and hydrogeological data on the Tocomar geothermal volcanic area (Puna plateau, Central Andes, NW Argentina), together with preliminary geochemical magnetotelluric data. The main reservoir is located within fractured Pre-Palaeozoic–Ordovician units. recharged by meteoric waters. Geothermal fluids upwell where regional structures intersect secondary associated development of basin. Preliminary indicate a temperature ∼ 200° C local gradient...
Mafic monogenetic volcanoes and salt pans or salars are ubiquitous in the Puna plateau of Central Andes. In this contribution, we present study two Pleistocene mafic centers, Panqueque center emplaced on western margin Salar de Arizaro Medialuna within same salar. Both centers had initial explosive phreatomagmatic activity that progressed to magmatic (Strombolian) ended with effusive activity. However, differences magma flux, bedrock composition, magma-water interaction resulted deposits...
Abstract. On 13 June 2015, the London Volcanic Ash Advisory Centre (VAAC) warned Buenos Aires VAAC about a possible volcanic eruption from Nevados Ojos del Salado volcano (6879 m), located in Andes mountain range on border between Chile and Argentina. A ash cloud was detected by SEVIRI instrument board Meteosat Second Generation (MSG) satellites 14:00 UTC June. In this paper, we provide first comprehensive description of event through observations numerical simulations. Our results support...
This paper presents a detailed geological map at the 1:20,000 scale of Tocomar basin in Central Puna (north-western Argentina), which extends over an area about 80 km2 and displays spatial distribution Quaternary deposits structures that cover Ordovician basement Tertiary sedimentary volcanic units. The new dataset includes litho-facies descriptions, stratigraphic structural data 234U/230Th ages for travertine rocks. reconstructed framework, along with analysis, has revealed complex...
