Phylogeny and historical biogeography of gnateaters (Passeriformes, Conopophagidae) in the South America forests
(Elsevier Inc.Maryland Heights, 2014-10)
We inferred the phylogenetic relationships, divergence time and biogeography of Conopophagidae (gnateaters) based on sequence data of mitochondrial genes (ND2, ND3 and cytb) and nuclear introns (TGFB2 and G3PDH) from 45 ...
Deep weathering and landscape evolution in a tropical plateau
(ELSEVIER SCIENCE BV, 2011)
The thick weathering profiles of humid tropical areas are an important, yet generally neglected, source of information on landscape evolution. Six complete profiles of the weathering mantle were sampled by drilling on the ...
Pliocene Orographic Barrier Uplift in the Southern Central Andes
(Geological Society Of America, 2014-08)
Sedimentary basin fills along the windward flanks of orogenic plateaus are valuable archives of paleoenvironmental change with the potential to resolve the history of surface uplift and orographic barrier formation. The ...
El Morro caldera (33° 10′ S, 66° 24′ W), San Luis, Argentina: An exceptional case of fossil pre-collapse updoming
(Elsevier Science, 2017-03)
Volcanism at Sierra del Morro represents the final stages of the flat-slab related magmatism in the easternmost San Luis Neogene Volcanic Belt. This ~80 km-long NW-WNW-trending belt tracks the episodic inland migration of ...
Assessing Groundwater Age in Confined Aquifers from the Central Pampean Plain of Córdoba, Argentina
(University of Arizona. Department of Geosciences, 2016-12)
In Córdoba Province, Argentina, the population uses groundwater from confined aquifer systems (CASs) for different activities. Therefore, it is necessary to carry out comprehensive studies in order to plan more sustainable ...
New data on neotectonic contractional structures in Precordillera, south of Río de La Flecha: Structural setting from gravity and magnetic data. San Juan, Argentina
(Elsevier, 2014-01)
The Central and Eastern Precordillera form oppositely verging thrust systems on the western and eastern sides of the Matagusanos-Maradona-Acequión valley, establishing a thick-skinned triangle zone with significant changes ...
The opening of the Magellan Strait and its geodynamic implications
(Wiley Blackwell Publishing, Inc, 2013-01)
The existence of a Neogene-Quaternary rift system responsible for the opening of the eastern Magellan strait has been one of the more peculiar tectonic features of the southernmost Andes since its discovery more than a ...
Barra de Tabatinga and Touros Formations: evidence of pleistocene hich sea-level stillstands of the Rio Grande do Norte coast
(Instituto de Geociências /Universidade Federal do Rio Grande do Sul, 2001)
Reassessment of Neovenericor Rossi de García, Levy & Franchi, 1980 (Bivalvia: Carditidae) using a geometric morphometric approach, and revision of planicostate carditids from Argentina
(Taylor & Francis Ltd, 2016-07-27)
Various systematic approaches have been applied to the Neogene planicostate carditids of Patagonia. Some authors have included these species within Venericor (known from the Eocene of North America and Europe) or in ...
Vent distribution in the Quaternary Payún Matrú Volcanic Field, western Argentina: Its relation to tectonics and crustal structures
(Elsevier Science, 2014-05)
The Payún Matrú Volcanic Field consists of two polygenetic and mostly trachytic volcanoes (Payún Matrú with a summit caldera and Payún Liso) along with around 220 scoria cones and basaltic lava flows. This volcanic field ...
