Origin, distribution, and geochemistry of arsenic in the Altiplano-Puna plateau of Argentina, Bolivia, Chile, and Perú
(Elsevier Science, 2019-05)
Elevated concentrations of arsenic in water supplies represent a worldwide health concern. In at least 14 countries of South America, high levels have been detected relative to international standards and guidelines. Within ...
Uplift of the Altiplano-Puna plateau: A view from the west
(American Geophysical Union, 2010-10)
The western flank of the Central Andean Plateau is a crustal‐scale monoclinal fold, expressed in the geomorphology and in the westward tilt of fore‐arc basin strata. Data from three fore‐arc basins quantify the magnitude ...
Northern Puna Plateau-scale survey of Li brine-type deposits in the Andes of NW Argentina
(Elsevier Science, 2018-07)
Salars of the Andean Plateau in the Central Andes are the largest lithium deposits on Earth. The most notorious are the Chilean Salar de Atacama, and Uyuni in the Bolivian Altiplano. Despite the relevance of the region ...
Thermal and geodynamic contributions to the elevation of the Altiplano-Puna plateau
(Elsevier Science, 2014-10)
The most remarkable feature of the Central Andes is the Altiplano–Puna plateau. This plateau is characterized by 3.5 km average elevation, approximately 70 km crustal thickness and very high heat flow. The upper mantle ...
Seismic interpretation and cenozoic tectonic evolution of the Pozuelos Basin, Andean plateau, Argentina
(Pergamon-Elsevier Science Ltd, 2021-01-24)
The Andean basin formation across the Altiplano-Puna plateau has been mostly associated with: (i) interconnected depozones within a simple eastward-migrating foreland, (ii) isolated depocenters in a broken foreland or (iii) ...
First data on volume and type of deflated sediment from Southern Puna Plateau and its role as source of the Chaco-Pampean loess
(Pergamon-Elsevier Science Ltd, 2017-05)
This paper presents the first attempt at qualitatively and quantitatively evaluating the sedimentary contribution of the Puna plateau to the loess and soils of the Argentinean Pampas. The origin of the Pampean sediment has ...
Ground/satellite observations and atmospheric modeling of dust storms originating in the high Puna-Altiplano deserts (South America): Implications for the interpretation of paleo-climatic archives
(American Geophysical Union, 2013-05-13)
This study provides a detailed description of the sources, transport, dispersion, and deposition of two major dust events originating from the high‐altitude subtropical Puna‐Altiplano Plateau (15?26°S; 65?69°W) in South ...
Synthesis: PLUTONS: Investigating the relationship between pluton growth and volcanism in the Central Andes
(Geological Society of America, 2018-06)
The Central Andes is a key global location to study the enigmatic relation between volcanism and plutonism because it has been the site of large ignimbrite-forming eruptions during the past several million years and currently ...
Geomorphology and spatial distribution of monogenetic volcanoes in the southern Puna Plateau (NW Argentina)
(Elsevier Science, 2019-06)
Monogenetic volcanoes are the most common volcanic landforms on Earth. Several works have shown that the study of geomorphology and spatial distribution of such small volcanoes reveals important aspects related to the ...
Neogene Mafic Magmatism in the Northern Puna Plateau, Argentina: Generation and Evolution of a Back-arc Volcanic Suite
(Oxford University Press, 2017-08)
Neogene back-arc mafic volcanism in the northern Puna Plateau produced a suite of mainly high-Mg, calc-alkaline, basaltic andesites to andesites that form small scoria cones and lava fields. We present the first comprehensive ...
