Approaches and challenges to the study of loess: Loess in Argentina, South America
(Academic Press Inc Elsevier Science, 2018-05)
In September 2016, the annual meeting of the International Union for Quaternary Research's Loess and Pedostratigraphy Focus Group, traditionally referred to as a LoessFest, met in Eau Claire, Wisconsin, USA. The 2016 ...
Loess of southern South America
(Pergamon-Elsevier Science Ltd, 2003)
Non-Classical Types of Loess
(Elsevier Science, 2007-12)
The purpose of this contribution is to describe the sequence of physical and chemical processes resulting in the sediment-type named loess, a fine-grained sediment deposit of universal occurrence. Owing to historical causes, ...
Geochemistry of a Late Quaternary loess-paleosol sequence in central Argentina: Implications for weathering, sedimentary recycling and provenance
(Elsevier Science, 2019-10)
A loess-paleosol sequence in the Pampean Plain, central Argentina was analyzed geochemically, in order to evaluate the weathering signature and sedimentary recycling as well as to analyze the origin of these loessic ...
The paleoclimatic message from the polymodal grain-size distribution of late Pleistocene-early Holocene Pampean loess (Argentina)
(Elsevier B.V., 2020-01)
Wind-blown dust deposits are considered one of the most important terrestrial archives for past climate change studies. In the Southern Hemisphere, the Pampean loess is the most extensive paleo-dust record, whose origin ...
Revisiting the chronology and environmental conditions for the accretion of late Pleistocene-early Holocene Pampean loess (Argentina)
(Pergamon-Elsevier Science Ltd, 2019-06)
The present research work reviews the age models of three previously studied loess sections across 700 km in the loess belt of the Pampean region in central Argentina. The loess sections were investigated for the first ...
Acoplamiento de los procesos de escurrimiento superficial e infiltración
(Universidad Nacional de Córdoba.Facultad de Ciencias Exactas, Físicas y Naturales, 2008)
Plantea la implementación de una nueva metodología alternativa a las existentes que permita obtener en forma simultánea el hidrograma de escurrimiento superficial e infiltración que genere además, curvas de perfiles de la ...
Wind erosion processes and related glyphosate transport in the loess pampean region of Córdoba province, Argentina
(2013)
The results of this experiment will provide: Insight on glyphosate and AMPA concentrations in wind-eroded sediment; Valuable information on the losses of glyphosate and AMPA to off-site environments due to wind erosion; ...
Light acidification in N-fertilized loess soils along a climosequence affected chemical and mineralogical properties in the short-term
(Elsevier, 2016-04)
Some evidences indicate that N-fertilization of crops decreased pH values of loess soils of the Argentinean Pampas in the last decades. We analyzed the A-horizons of four N-fertilized (F) and non-fertilized (NF) paired ...
