Changes in the As solid speciation during weathering of volcanic ashes: A XAS study on Patagonian ashes and Chacopampean loess
(Pergamon-Elsevier Science Ltd, 2017-09)
X-ray absorption spectroscopy (XAS) was used to determine the oxidation state of As, local chemical coordination and the relative proportion of different As species in recent and ancient Andean volcanic ashes, as well as ...
Dating volcanic ash and pumice stones from volcano El Misti, Peru, by thermoluminescence
(ElsevierNL, 2019-04)
El Misti is one of active volcanos in Peru, and known because it is located close to an important city of Arequipa, at about 17 km. There has been in the past several eruptions and the volcano is covered with lava, ash, ...
Modeling volcanic ash resuspension - Application to the 14-18 October 2011 outbreak episode in central Patagonia, Argentina
(Copernicus Publications, 2014-01)
Volcanic fallout deposits from the June 2011 Cordón Caulle eruption on central Patagonia were remobilized in several occasions months after their emplacement. In particular, during 14-18 October 2011, an intense outbreak ...
Examining the influence of meteorological simulations forced by different initial and boundary conditions in volcanic ash dispersion modelling
(Elsevier, 2016)
Abstract: The performance of the combination of the Fall3D ash dispersion model with the Weather Research and Forecast (WRF) meteorological model in the southern cone of South America under two initial and boundary conditions ...
Impacts of the June 2011 Puyehue-Cordón Caulle volcanic complex eruption on urban infrastructure, agriculture and public health
(Institute of Geology and Nucelar Sciences, 2013-01-01)
Impacts of the June 2011 Puyehue-Cordón Caulle volcanic complex eruption on urban infrastructure, agriculture and public health in Argentina were studied by an interdisciplinary team from New Zealand, the United Kingdom ...
Antimony speciation in soils, sediments and volcanic ashes by microwave extraction and HPLC-HG-AFS detection
(2016)
On the 5th of May 2008, the first recorded eruption of the Chaiten Volcano in southern Chile occurred. Because one of the main natural sources of Sb is volcanic activity, it was necessary to study the distribution of Sb ...
Fossilization model for squamastrobus tigrensis foliage in a volcanic-Ash deposit: Implications for preservation and taphonomy (podocarpaceae, lower cretaceous, Argentina)
(Society for Sedimentary Geology, 2018-07)
The present study is a holistic approach to the relationship between volcaniclastic host rock characteristics and the fossilization processes of short leafy coniferous branches of Squamastrobus tigrensis, preserved as ...
