Surface uplift and convective rainfall along the southern Central Andes (Angastaco Basin, NW Argentina)
(Elsevier Science, 2016-04)
Stable-isotopic and sedimentary records from the orogenic Puna Plateau of NW Argentina and adjacent intermontane basins to the east furnish a unique late Cenozoic record of range uplift and ensuing paleoenvironmental change ...
Soluble iron inputs to the Southern Ocean through recent andesitic to rhyolitic volcanic ash eruptions from the Patagonian Andes
(American Geophysical Union, 2015-07)
Patagonia, due to its geographic position and the dominance of westerly winds, is a key area that contributes to the supply of nutrients to the Southern Ocean, both through mineral dust and through the periodic deposits ...
Cation exchange capacity and mineralogy of loess soils with different amounts of volcanic ashes
(Elsevier, 2014-05)
The cation exchange capacity of soils (CEC) is largely affected by the mineralogy of their parent material. Soils of the Argentinean Pampas develop on illitic loess, mixed, in variable proportions, with volcanic ashes. ...
Surface vitrification caused by natural fires in Late Pleistocene wetlands of the Atacama Desert
(Elsevier, 2017-07-01)
We describe extended occurrences of unusual silicate glass surface layers from the Atacama Desert (Chile). These glasses, found near the town of Pica at four localities separated by up to 70 km, are neither fulgurites, nor ...
Eocene volcanism in the Fuegian Andes: Evidence from petrography and detrital zircons in marine volcaniclastic sandstones
(Pergamon-Elsevier Science Ltd, 2020-12)
The sedimentology, petrography, and U–Pb dating of two Eocene volcaniclastic horizons of the Punta Torcida and Leticia formations, Austral basin, Tierra del Fuego, Argentina are interpreted and documented. The volcaniclastic ...
Materiales parentales de los suelos de la Llanura Pampeana: El aporte volcánico andinoParent materials of Pampean plain soils: The Andean volcanic source
(Asociación Argentina de la Ciencia del Suelo, 2020)
La mayor parte de los suelos pampeanos se desarrollan a partir de una extensa cubierta sedimentaria de depósitos loéssicos hacia el este y mantos de arena -campos de dunas hacia eloeste, acumulados principalmente en los ...
Geologic reconnaissance of Lautaro Volcano, Chilean Patagonia

The sedimentology, petrography, and U-Pb dating of two Eocene volcaniclastic horizons of the Punta Torcida and Leticia formations, Austral basin, Tierra del Fuego, Argentina are interpreted and documented. The volcaniclastic ...
A spectrum of disequilibrium melting preserved in lava-hosted, partially melted crustal xenoliths from theWudalianchi volcanic field, NE China
(Elsevier, 2015)
Disequilibrium melting has been established as a common process occurring during crustal anatexis and thus demonstrates that crustal assimilation is not a closed system. Observations of extreme compositional heterogeneity ...
