Miocene fragmentation of the Central Andean foreland basins between 26 and 28°S
(Pergamon-Elsevier Science Ltd, 2019-10)
We present new U-Pb LA-ICP-MS data from the Central Andean foreland basins combined with new and published stratigraphic information in order to reconstruct the Miocene fragmentation of the Andean foreland between 26 and ...
Relative soil water content as a factor for wind erodibility in soils with different texture and aggregation
(Elsevier, 2019-04)
The soil water content is one of the main factors influencing the beginning of soil particle movement by the wind. Although, some authors studied the effect of soil water content on threshold wind velocity and have defined ...
La Meseta de Somún Curá: Los sonidos de la piedra
(Servicio Geológico Minero Argentino, 2008-06)
Capítulo del libro Sitios de Interés Geológico editado por SEGEMAR.El paisaje más descollante del sur de las provincias de Río negro y Chubut, es al mesta de Somún Curá. La meseta está constituida por extensos mantos de ...
Modern microbial mats in siliciclastic tidal flats: Evolution, structure and the role of hydrodynamics
(Elsevier Science, 2014-01)
Microbial mats in coastal environments play an important role in both stabilizing the sediment and preserving sedimentary structures. They represent the first biological systems that appeared on Earth, even forming large ...
Using beryllium-7 to evaluate soil erosion processes in agricultural lands in semiarid regions of Central Argentina
(Springer Verlag Berlín, 2018-08)
This work presents the results of a soil erosion study using the 7Be technique. This technique estimates the water erosion/deposition from the comparison between 7Be soil content of a reference site and an eroded or ...
Influence of macrobenthos ( Meretrix meretrix Linnaeus ) on erosion‐accretion processes in intertidal flats: A case study from a cultivation zone
(John Wiley & Sons Inc, 2020-01)
The activity of benthic organisms can strongly influence sediment dynamics in anintertidal flat. However, few studies have conducted a quantitative assessment of the effect of benthic organisms on erosion-accretion processes ...
A wind-tunnel study on saltation and PM10 emission from agricultural soils
(Elsevier, 2016-09)
PM10 emission depends on the texture and the aggregation state of a soil. A decisive but less studied factor is the saltation fraction of the soil (fraction between 100 and 500 μm). Six soils of contrasting textures were ...
Constraining erosion rates in thrust belts: Insights from kinematic modeling of the Argentine Precordillera, Jachal section
(Elsevier Science, 2019-05)
Kinematic restorations in fold and thrust belts, which are a valuable tool for studying the deformational history of fold and thrust belts, have been poorly used to understand erosion rates. In this contribution, we estimated ...
Effects of sequential exposure to water accommodated fraction of crude oil and chlorpyrifos on molecular and biochemical biomarkers in rainbow trout
(Elsevier Science Inc, 2018-10)
Fish can be simultaneously or sequentially exposed to various kinds of pollutants, resulting in combined effects. Polycyclic aromatic hydrocarbons induce cytochrome P450 monooxygenase 1A (CYP1A) expression, which catalyzes ...
Desert pavements as indicators of soil erosion on aridic soils in north-east Patagonia (Argentina)
(Elsevier Science, 2011-11-24)
Desert pavements are prominent features of many geomorphic surfaces in arid and semiarid lands. In the semiarid soils of north-eastern Patagonia, gravel cover in the shrub interspace areas of shrub-dominated communities ...
