Geographic provenance of aeolian dust in East Antarctica during Pleistocene glaciations: preliminary results from Talos Dome and comparison with East Antarctic and new Andean ice core data
(Pergamon-Elsevier Science Ltd, 2010-01)
The strontium and neodymium isotopic signature of aeolian mineral particles archived in polar ice cores provides constraints on the geographic provenance of dust and paleo-atmospheric circulation patterns. Data from different ...
Neogene activity of the Barrancas Bancas Fault and its relationship with Hydrothermal and volcanic activity
(8th International Symposium on Andean Geodynamics (ISAG)EC, 2019-09)
The chronology and nature of the Neogene-Cuaternary deformation in the Central Volcanic Zone (CVZ) in the north of Chile is partially unclear. Some authors have identified compression in isolated areas of the western slopes ...
Petrogenesis of peraluminous magmas in the Central Andean backarc: the Huayra Huasi Volcanic Complex, NW Argentina
(Springer, 2021-07)
The Huayra Huasi Volcanic Complex of Miocene age (11.88±0.15 Ma U–Pb zircon) was emplaced in the Northern Puna plateau of Argentina, spatially associated with ignimbrites erupted from Altiplano–Puna Volcanic Complex calderas. ...
Thermochronologic Evidence for Late Eocene Andean Mountain Building at 30°S
(American Geophysical Union, 2017-11)
The Andes between 28° and 30°S represent a transition between the Puna-Altiplano Plateau and the Frontal/Principal Cordillera fold-and-thrust belts to the south. While significant early Cenozoic deformation documented in ...
The paleoclimatic message from the polymodal grain-size distribution of late Pleistocene-early Holocene Pampean loess (Argentina)
(Elsevier B.V., 2020-01)
Wind-blown dust deposits are considered one of the most important terrestrial archives for past climate change studies. In the Southern Hemisphere, the Pampean loess is the most extensive paleo-dust record, whose origin ...
Estilos Estructurales y Deformación, en el margen Occidental de los Andes Centrales del Norte de Chile (27°-29° S)
(2012)
La diversidad de estilos estructurales confinados directamente en el Altiplano-Puna plateau, así como el grado de acortamiento y engrosamiento cortical del mismo, siempre se ha relacionado con el tipo de subducción bajo ...
Human populations and environments during the Middle Holocene in the South-Central Andes
(Elsevier, 2013-09)
The South-Central Andes include some of the highest and some of the widest sections of this major orographic chain, and includes several volcanoes, as well as intermediate depressions and the Altiplano plateau, which is ...
Screening fitoquímico, antimicrobiano y antioxidante de plantas pre-andinas y del altiplano chileno
(Universidad de ChileCyberDocs, 2009)
El altiplano o puna por sus características ambientales, es una región natural única en
América del Sur, abarca el centro y sur del Perú, el norte de Chile, parte de Bolivia, y el
noreste de Argentina. En el altiplano ...
Frogs at the summits: phylogeny of the Andean frogs of the genus Telmatobius (Anura, Telmatobiidae) based on phenotypic characters
(Wiley Blackwell Publishing, Inc, 2017-02)
A phylogenetic hypothesis for the frogs of the genus Telmatobius that includes a comprehensive sample of the morphological and geographical variation is lacking. To obtain such hypothesis constitutes the main focus of this ...
