Late Miocene to recent morphotectonic evolution and potential seismic hazard of the northern Lerma valley: Clues from Lomas de Medeiros, Cordillera Oriental, NW Argentina
(Elsevier Science, 2013-11)
The Lomas de Medeiros are low relief hills located at the northern extreme of the Lerma valley, where new structural, morphological and topographic key data have been collected and integrated with the available stratigraphic ...
A note of caution on the use of boulders for exposure dating of depositional surfaces
(Elsevier Science, 2011-02)
Exposure dating of boulders has been widely applied to determine the age of depositional surfaces under the assumption that the pre-depositional nuclide component in most boulders is negligible. Here we present a case study ...
Evaluación geotécnica del área de Los Aceitunos en la mina de carbón Paso Diablo, municipio Mara, estado Zulia

Refolding ofthin-skinned thrust sheets by active basement-involved thrust faults in the eastern Precordillera of western ArgentinaReplegamiento de láminas de corrimiento epidérmicas mediante fallas inversas de basamento activas en la Precordillera Oriental del oeste de Argentina
(Asociación Geológica Argentina, 2006-12)
La deformación activa en el oeste de Argentina está reflejada por terremotos devastadores como el sismo de San Juan en 1944. Aunque el terremoto causó un daño considerable a San Juan, la fuente del terremoto permanecía ...
Ethanol adsorption on MgO surface with and without defects from a theoretical point of view
(Elsevier Science, 2009-04-20)
In this work, the ethanol adsorption on a perfect MgO(1 0 0) surface, and also on topologic surface defects of MgO, is studied. Terrace, edge and corner sites were analyzed, whose O and Mg ions are five, four and three ...
Les formations quaternaires du Bassin de Huancayo et leur néotectonique (Andes Centrales Péruviennes)
(Université de Paris. Faculté des sciences. Laboratoire de géographie physiqueFR, 1968)
In the Huancayo-Jauja intra-Andean basin, whose origin seems to be linked to a warping of the «Puna» tertiary erosion surface, an important set of quaternary formations was deposited. The oldest one is the «Jauja» lacustrine ...
Morfotectónica y dataciones del fallamiento activo del piedemonte llanero, colombia, sudamérica
(Universidad Nacional de Colombia, Facultad de Ciencias Humanas, Departamento de Geografía, 2007)
Sobre el piedemonte llanero en la región central de Colombia, se aprecian numerosas evidencias de fallamiento activo asociado al Sistema de Falla del Borde Llanero. Este trabajo presenta los resultados de estudios ...
Adsorption of 2-propanol on MgO Surface: A Combined Experimental and Theoretical Study
(Elsevier Science, 2014-12-04)
The adsorption of 2-propanol (or isopropanol) on MgO was studied using infrared (IR) spectroscopy and density functional theory (DFT) simulations. The analysis of IR spectra indicates that the molecule can adsorb either ...
First record of OSL‐dated fluvial sands in a tropical Andean cave reveals rapid late Quaternary tectonic uplift
(Wiley, 2021-06)
We present the first results of OSL‐dated fluvial sands extracted from a riverside cave in the tropical Andes. The excellent agreement between the ages of the various samples allowed the calculation of a late Quaternary ...
Análisis geomorfológico y paleoambiental de la depresión tectónica de Ullum-Zonda, Provincia de San JuanGeomorphological and paleoenvironmental analysis of the Ullum-Zonda tectonic depression, Province of San Juan
(2019-03-19)
El objetivo de la presente tesis doctoral es evaluar la evolución geomorfológica del valle de Ullum-Zonda y las condiciones paleoambientales que prevalecieron en esta depresión durante el Cuaternario tardío. Para ello, se ...
