Introduction
My main interests are geomorphological processes, particularly those related to natural hazards. I'm focused on neotectonic faults and folds in the Central Andes and their landscape signature. Also I study mass wasting processes in Patagonian Andes, and their relationship with seismic and climate triggerings.

Presentation
Les Babors orientaux font partie de la chaîne des Maghrébides formée par l'orogenèse alpine. Cette section de l'Atlas Tellien est marquée par un relief typique soumis à une activité à la fois tectonique et érosive constatée à travers sa morphologie accidentée et ses vallées profondes. Cette étude met en évidence le lien entre la dynamique externe e...
Article
The Eastern Babors are part of the Maghrebides chain formed by the alpine orogeny. This section of the Tellian Atlas is marked by a typical relief subjected to both tectonic and erosive activity observed in its rugged morphology and deep valleys. The paper highlights the link between external dynamics and neotectonic processes through the analysis...
Article
The Guañacos fold and thrust belt, in the northern Neuquén Andes (37°-38°S; 70°30′-71°10′W), has been studied by many researchers focusing on the Quaternary tectonic activity, from a morphological to a structural perspective. Additionally, this portion of the Andes is quite peculiar due to the numerous geomorphic processes coeval with neotectonic,...
Article
Glacial and fluvial landforms record the recent history of the Earth surface and have the potential to provide information about uplift and climate changes during Quaternary times. Patagonia hosts uniquely well-preserved moraine deposits, along with outwash and fluvial terraces. This offers the possibility of determining the timing of glacier advan...

The present work focuses on the south tip of the more than 120 km long Matagusanos-Maradona-Acequión tectonic depression, located between the Eastern and Central Precordillera in San Juan province, Argentina. A reverse fault scarp, associated with the Quaternary activity of the east vergent-Acequión fault was analyzed. This fault scarp has an avera...

Un sismo de Mw 5,9 se registró 34 km al este de Humahuaca, cuyo mecanismo focal se asocia a una falla normal de orientación ENE. Registros audiovisuales mostraron numerosas caídas de rocas inducidas por el evento. Se discuten las principales características del sismo y la remoción en masa asociada.

Full-text available
Quaternary deformations described in the retro-arc region at the latitudes of the Neuquén Basin can be divided into two main groups: a northern group characterized by Quaternary deformation zones concentrated near the main topographic breaks of different morphostructural systems, and a second group located in the southern Neuquén Basin distinguishe...
Article
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous. Evidence of Quaternary deformation has been described in the northern part of it (34–34.5°S), potentially co...

The Auca Mahuida volcanic field lies on the southernmost Payenia Volcanic Province, one of the broadest retroarc volcanic plateaux in the southern Central Andes (~38°S). This voluminous basaltic flooding of Quaternary age was originated from a deep asthenospheric source, interpreted as a mantle plume product of changing slab dynamics. The geometry...
Article
Quaternary deformation in the Southern Central Andes between 36° and 38ºS is disconnected, noncontinuous and not particularly tracing the main mountain topographicfronts. This pattern contrasts to the one to the north through the Chilean-Pampean flat subduction system, where continuous neotectonic structures develop at the feet of the main active s...

A broad range of processes act today and have acted simultaneously during the Quaternary, producing relief from the Chilean coast, where the Pacific Ocean floor is sinking underneath the South American margin, to the Brazilian and Argentine Atlantic Ocean platform area. This picture shows to be complex and responds to a variety of processes which a...

Sobre el faldeo nororiental del cerro Negro, en el extremo norte del valle de El Bolsón, en la Cordillera Patagónica de Río Negro, un corte de ruta expone un afloramiento de depósitos glaciarios de aproximadamente 400 metros de longitud. En dicha localidad se observaron una serie de rasgos deformacionales cuya descripción y análisis son objeto de e...

On the northeast face of Cerro Negro, in the northern extreme of the El Bolsón valley in the Patagonian Cordillera of Río Negro, a road cut left an outcrop of around 400-meters length of glacigenic deposits. In thislocation, some deformational features were observed, whose description and analysis are objects of this work. Through the development o...

los estadios y mecánicas deformacionales que afectaron al segmento de transición que va desde los Andes Centrales Australes hasta los Patagónicos Septentrionales. De esta forma surge un cuadro complejo en el cual se alternan segmentos con topografías y amplitudes contrastantes, grados de acortamiento variables, cuencas de antepaís en la región fron...

A range of processes acted during the Quaternary producing topography from the Chilean coast, where the Pacific ocean floor is being subducted, to the Brazilian-Argentinean Atlantic platform area: On one hand, active mountains in the passive margin whose origin is discussed; and on the other hand, processes associated with the activity of the easte...

La laguna Derrumbe es un cuerpo de agua ubicado en los Andes Norpatagónicos en la provincia de Chubut, Argentina. Está contenida en un circo glaciario y endicada por una morena frontal del glaciar homónimo. A través del reconocimiento de campo se pudo describir a esta laguna y a un importante depósito rocoso que se halla aguas abajo de la misma, in...

The Laguna Derrumbe is a body of water located in the North Patagonian Andes, in Chubut province, Argentina. This lake is contained in a glacial cirque and dammed by the terminal moraine of the namesake glacier. Through field survey it was possible to describe this lake and an important rocky deposit downstream of it, which is interpreted as an out...
