Genesis of the La Espingarda kaolin deposit in Patagonia
(Elsevier Science, 2010-02)
The La Espingarda kaolin deposit was formed by "in situ" alteration of sub-alkaline rhyolites belonging to the Jurassic Marifil Formation. Three altered volcanic lithofacies were identified: a porphyric biotitic ignimbrite ...
Influence of climate change on the predicted distributions of the genus Tympanoctomys (Rodentia, Hystricomorpha, Octodontidae), and their conservation implications
(Alliance Communications Group Division Allen Press, 2020-08)
Viscacha rats (genus Tympanoctomys Yepes, 1942) are ecologically, physiologically, and behaviorally unusual octodontid rodents endemic to the Monte and Patagonian desert biomes of Argentina. The geographic ranges of the ...
Invertebrados del Cenozoico de la ArgentinaCenozoic invertebrates of Argentina
(Asociación Paleontológica Argentina, 2007-11)
The Cenozoic rocks of Argentina contain a rich, exceptionally well preserved and remarkable diverse marine and continental invertebrate fauna. The main goal of the present synthesis consists in revealing the continuous ...
Geochemical characterization, correlation, and optical dating of tephra in alluvial sequences of central western Argentina
(Academic Press Inc Elsevier Science, 2004-07)
The synthesis of paleoclimatic archives provided by loess and alluvial sequences of central Argentina has been hindered by the lack of a cohesive lithostratigraphic framework extending across the Chaco-Pampean plains and ...
Patagonian ostracods as indicators of climate-related hydrological variables: Implications for paleoenvironmental reconstructions in Southern South America
(Springer, 2012-09)
Different precipitation regimes across Patagonia generate an environmental gradient that is expected to reflect upon the solute composition and concentration of lake water through the ensuing differences in water balance. ...
Análise de séries temporais via grafo de visibilidade horizontal e teoria da informação
(Universidade Federal de Minas GeraisUFMG, 2016-04-25)
The method called Horizontal Visibility Graph (Horizontal Visibility Graph - HVG) [B Luque et al., Phys. Rev. E 80: 046103 (2009)], has the function of converting a time series into a graph. This method has been used to ...
Dating kaolinite from the Neogene Içá Formation and overlying laterites, central Amazonia, Brazil: Constraints for a stratigraphic correlation
(2020-09-15)
The Neogene Içá Formation is a major sedimentary deposit in central Amazonia (Brazil) that is critical to the understanding and modeling of the evolution of the Amazon Basin. However, its chronostratigraphy is poorly ...
Tropical precipitation anomalies and d‐excess evolution during El Niño 2014‐16
(2016)
The last 2014-16 El Niño event was among the three strongest episodes on record. El Niño considerably changes annual and seasonal precipitation across the tropics. Here, we present a unique stable isotope data set of daily ...

Reconstruction of neogene sea surface temperatures in Ceara Rise (South Atlantic) based on alkenones
(2016-05-19)
The Ceara Rise is a seismic peak located in the Atlantic Ocean and receives both marine and terrigenous sediments. These sediments are important for understanding the paleoclimatic and paleo-environmental conditions in the ...
