10Be surface exposure dating of the last deglaciation in the Aare Valley, Switzerland
(Birkhauser Verlag Ag, 2018-04)
The combined Rhone and Aare Glaciers presumably reached their last glacial maximum (LGM) extent on the Swiss Plateau prior to 24 ka. Two well-preserved, less extensive moraine stades, the Gurten and Bern Stade, document ...
A note of caution on the use of boulders for exposure dating of depositional surfaces
(Elsevier Science, 2011-02)
Exposure dating of boulders has been widely applied to determine the age of depositional surfaces under the assumption that the pre-depositional nuclide component in most boulders is negligible. Here we present a case study ...
In situ cosmogenic 3He and 36Cl and radiocarbon dating of volcanic deposits refine the Pleistocene and Holocene eruption chronology of SW Peru
(Springer, 2019-11-07)
Constraining the age of young lavas, which generally fall outside the effective range of traditional geochronology methods, remains a key challenge in volcanology, limiting the development of high-resolution eruption ...
Climatic and Tectonic forcing on alluvial fans in the Southern Central Andes
(Pergamon-Elsevier Science Ltd, 2017-09)
Mountainous regions and their forelands commonly support a suite of landforms sensitive to climate change and tectonics. Alluvial fans in particular, are prominent geomorphological features in arid and semiarid regions ...
Timing and extent of late pleistocene glaciation in the arid central andes of Argentina and Chile (22°-41°s)
(Universidad de La Rioja, 2017-07)
The arid Central Andes are a key site to study changes in intensity and movement of the three main atmospheric circulation systems over South America: the South American Summer Monsoon (SASM), the Westerlies and the El ...
The large MIS 4 and long MIS 2 glacier maxima on the southern tip of South America
(Elsevier Ltd, 2021)
© 2021 Elsevier LtdRobust glacial chronologies are needed to address the fundamental questions of when and why Ice Age climates begin and end. Well-preserved glacial deposits left by large ice sheet lobes adjacent to ...
Using 10Be cosmogenic surface exposure dating to determine the evolution of the Purgatorio active fault in the Andean forearc, southern Peru
(EGU General AssemblyAT, 2015-04)
Active transpressive deformation has been occurring along the Andean hyperarid forearc for the last 3 Myrs but many of these faults are still not described even if able to produce large damaging earthquakes. Active faulting ...
Impacto de la altura en el embarazo y en el producto de la gestación
(Instituto Nacional de Salud, 2012)
This review describes adverse outcomes in pregnancy after brief, intermittent, or permanent residence at high altitudes. Review of literature shows that congenital malformations rates are higher at high altitudes. Additionally, ...
Active transpressional tectonics in the Andean forearc of southern Peru quantified by 10Be surface exposure dating of an active fault scarp
(American Geophysical UnionUS, 2017-09)
Our understanding of the style and rate of Quaternary tectonic deformation in the forearc of the Central Andes is hampered by a lack of field observations and constraints on neotectonic structures. Here we present a detailed ...
Latest Pleistocene and Holocene glacier fluctuations in southernmost Tierra del Fuego, Argentina
(Elsevier, 2013-01)
Some researchers propose that summer insolation controls long-term changes in glacier extent during the Holocene. If this hypothesis is correct, the record of glacier fluctuations at high latitudes in the Southern Hemisphere ...
