Tectonic segmentation across Patagonia controlled by the subduction of oceanic fracture zones
(Pergamon-Elsevier Science Ltd, 2020-12)
A set of fracture zones left by transform faults segmenting the active Chile Ridge that separates the Nazca and Antarctica Plates has been subducting beneath western Patagonia in the last 18 Myr. The subduction direction ...
Estado actual del conocimiento del orden Odonata en la PatagoniaCurrent knowledge of Patagonian Odonata
(Sociedad Entomológica Argentina, 2009-06)
The Odonata order is represented in Patagonia by 36 species belonging to nine families and 18 genera. The endemicity level is high being approximately 60% of the species and 40% of genera endemic. The specific richness in ...
Paleogene arc-related volcanism in the Southern Central Andes and North Patagonia (39°-41°S).
(Springer, 2018)
The influence of tectonic processes in evolution of magmatic suitesevaluated through their geochemical signature has always been a subject of debate.Late Paleocene arc volcanism in the Southern Central Andes, particularly ...
Coastal Geology and morphology of Patagonia and the Fuegian Archipelago
(Elsevier, 2008)
The World is not a perfect sphere and continents are not proportionally distributed in it. The Northern Hemisphere is dominated by land and the Southern Hemisphere is so by oceans. Patagonia and Tierra del Fuego are the ...
Vicariance events shaping Southern South American insect distributions
(Wiley Blackwell Publishing, Inc, 2016-09)
The main goal of this study is to use multiple insect phylogenies along with geographical information to test known vicariance hypotheses for Southern South America. We analysed the phylogenies and geographical distributions ...
A review about the mechanisms associated with active deformation, regional uplift and subsidence in southern South America
(Pergamon-Elsevier Science Ltd, 2015-12)
A broad range of processes acted simultaneously during the Quaternary producing relief in the Andes and adjacent foreland, from the Chilean coast, where the Pacific Oceanfloor is being subducted beneath South American, to ...
The Introduction of the Bow and Arrow Across South America’s Southern Threshold Between Food-Producing Societies and Hunter-Gatherers
(Springer, 2020)
This study presents a discriminant analysis of projectile points (n=44) from late Holocene contexts (ca. 3100-400 cal BP) in the Argentine Andes (29-37°S). About two thousand years ago, the groups that inhabited the regions ...
Las cargas: Characterization and prehistoric use of a southern andean obsidian source
(John Wiley & Sons Inc, 2015-03)
The importance of obsidian from the northern Patagonian source at Las Cargas is reflected in its early use (~8000 years B.P.) and extensive geographic diffusion but is nonetheless surprising in light of the source's high ...
El alto de Copahue-Pino Hachado y la fosa de Loncopué: un comportamiento tectónico episódico, Andes neuquinos (37º-39ºS)The Copahue-Pino Hachado high and the Loncopuè trough: An episodic tectonic behaviour, Neuquén Andes (37º- 39ºS)
(Asociación Geológica Argentina, 2005-12)
Los Andes de la parte central de Neuquén (38º-39ºS), enmarcados en los Andes Centrales Australes (35º-39ºS), han poseído una cronología de levantamiento similar al resto de los Andes Patagónicos Septentrionales (39º-46ºS) ...
The Miocene foreland basins of Northern Patagonia: sediment transfer systems from the Southern Andean to the Atlantic shelf
(Universität Hamburg, 2019)
Unravelling the effects of external controls on the stratigraphic record of a region, as well as the determination of how they impact in the dynamics of a sedimentary system is nowadays a critical gap to solve in geosciences. ...
