Cenozoic deformational processes in the North Patagonian Andes between 40º and 43ºS
(Springer, 2015)
The Cenozoic tectonic evolution of the North Patagonian Andes is analyzed linking geological and geophysical data in order to decipher the deformationalprocesses that acted through time and relate them to basin formation. ...
Tectonic Evolution of the Northern Patagonian Andes (40°S)
(Springer, 2015)
This chapter is focused on the tectonic evolution of the North PatagonianAndes comprised between 38° and 40°S. Field recognition of main structuresallowed establishing a structural control for the main sedimentary packages ...
Dendrogeomorphic reconstruction of flash floods in the Patagonian Andes
(Elsevier Science, 2015-01)
Flash floods represent a significant natural hazard in small mountainous catchments of the Patagonian Andes and have repeatedly caused loss to life and infrastructure. At the same time, however, documentary records of past ...
Tectonic evolution of the northern Austral-Magallanes basin in the Southern Patagonian Andes from provenance analysis
(Pergamon-Elsevier Science Ltd, 2019-11)
We studied the northern tip of the Austral-Magallanes basin in the Southern Patagonian Andes, between the Buenos Aires Lake and the Mayer River at 46°35′ SL and 48°35′ SL, respectively. Proposed objectives were: i) to ...
Little ice age fluctuations of Glaciar Río Manso in the north Patagonian Andes
(Academic Press Inc Elsevier Science, 2009-10)
Little Ice Age (LIA) fluctuations of Glaciar Río Manso, north Patagonian Andes, Argentina are studied using information from previous work and dendrogeomorphological analyses of living and subfossil wood. The most extensive ...
Retroarc deformation and exhumation near the end of the Andes, southern Patagonia
(Elsevier, 2013)
The southern Patagonian Andes constitute the narrow, high-latitude end of the Andean orogen belt in South America, where inherited basin paleogeography, subduction processes, retroarc crustal thickening, and late Cenozoic ...
The metamorphic rocks of the Nunatak Viedma in the Southern Patagonian Andes: Provenance sources and implications for the early Mesozoic Patagonia-Antarctic Peninsula connection
(Journal of South American Earth Sciences, 2019-03)
The Nunatak Viedma within the Southern Patagonian Icefield has been considered as a volcanic center based on its geomorphologic features, despite the fact that field explorations by Eric Shipton determined its metamorphic ...
Species tree phylogeny, character evolution, and biogeography of the patagonian genus Anarthrophyllum Benth. (Fabaceae)
(Springer Heidelberg, 2018-03)
Geologic events promoting the aridization of southern South America contributed to lineage divergences and species differentiation through geographic (allopatric divergence) and biotic and abiotic factors (ecological ...
Tectonic models for the Patagonian orogenic curve (southernmost Andes): An appraisal based on analog experiments from the Fuegian thrust-fold belt
(Elsevier Science, 2016-03)
Tectonic models for the evolution of the Patagonian orogenic curve were evaluated using analog experiments that considered either a rotational or a non-rotational orogenic backstop, combined with a basement promontory on ...
Folding, thrusting and development of push-up structures during the Miocene tectonic inversion of the Austral Basin, Southern Patagonian Andes (50°S)
(Elsevier Science, 2017-03)
Rift and post-rift sections of the Austral Basin in the Southern Patagonian fold and thrust belt were examined in outcrop and in 2D seismic reflection sections to evaluate geometric and kinematic aspects of the extension ...
