Article
Full-text available
Whereas the large-scale morphology and dynamics of orogenic wedges are well explained by critical-taper theory, many questions remain unanswered regarding the details of how deformation is accommodated internally. Here, we investigate the dynamics of a collisional orogenic wedge bounded by an over-thickened continental plateau, using two-dimensiona...
Article
Full-text available
Although the Himalayan range is classically presented as cylindrical along strike, segmentation of the range in terms of structure, topography, precipitation, and erosion patterns is becoming widely recognized. The potential climatic or tectonic controls on these lateral variations remain controversial. Thermokinematic models predict that the geome...

Full-text available
Although the Himalayan range is traditionally presented as cylindrical, its geological structure, topography, precipitation, and exhumation patterns all vary significantly along-strike. The potential climatic or tectonic controls on these spatially variable topographic, precipitation and exhumation patterns have been widely discussed in recent year...
Article
Full-text available
The El Oro complex, southwestern Ecuador, is a tilted section of the metasedimentary Ecuadorian forearc, which was partially molten during Triassic time due to gabbroic magma emplacement. Pressure and maximum temperature estimates show that the metamorphic gradient during anatexis was 45 °C/km in the upper crust and 10 °C/km in the 7-8 km garnet- b...

The El Oro Complex, southwestern Ecuador, is a tilted section of the metasedimentary Ecuadorian forearc, which has been partially molten during Triassic times due to gabbroic magma emplacement. This complex underwent a single and short (less than 10 Ma) anatectic event and is an ideal location to study magmatic underplating, migmatite formation, ma...

Although the Himalayan range is commonly presented as cylindrical along-strike, geological structures, topography, precipitation, and exhumation rates as recorded by low-temperature thermochronology data all vary significantly from west to east. In particular, segments of the belt that are characterized by a clear topographic step between the Lesse...
Article
Full-text available
The El Oro metamorphic province of SW Ecuador is a composite massif made of juxtaposed terranes of both continental and oceanic affinity that has been located in a forearc position since Late Paleozoic times. Various geochemical, geochronological and metamorphic studies have been undertaken on the El Oro metamorphic province, providing an understan...
Poster
It is now widely accepted that the formation and the evolution of high elevation plateaus such as the Tibet and the Altiplano-Puna are strongly linked to mantel magma underplating at crustal root level and partial melting of the lower crust. Understanding the rheological behavior of the deep continental crust during these episodes is therefore cruc...
Presentation
The Karnali region of western Nepal shows several anomalous features in terms of structural evolution and topography with respect to neighbouring transects in the central Nepal and Kumaong Himalayas. This area is, therefore, of major importance to understand the recent structural and tectonic evolution of the Himalaya. Several important aspects of...

Poster
Despite much progress, many questions remain regarding the potential dynamic coupling between atmospheric and lithospheric processes in the long-term evolution of mountain belts. Recent studies (e.g., Whipple and Meade 2004, Stolar et al. 2006) have reported models that predict a powerful climatic control on orogen evolution and distinct, potential...
