The continental crust above the flat slab has very heterogeneous seismic properties which correlate with important deformation structures and geological terranes at the surface.

The alluvial plain would be relatively thicker downstream of the study area siskique 30 to 50m. All documents in ORBi are protected by a user license. We confirm previous studies that have shown that the thick lower crust of the present day Andean arc is non-eclogitized and maybe gomographie the felsic Chilenia terrane, whereas to the east, the Cuyania terrane in the backarc is more mafic and contains an eclogitized lower crust.


In International Parallel and Tomotraphie. The aim of our study is to assess, using a thermo-petrological-seismological approach, the differences of the overriding lithosphere between these two regions, in order to better understand the deep structure of the continental lithosphere above the flat slab, and the links between the deformations at the surface and at depth.

In upstream of the alluvial plain, near the river, these methods were used to map the sandy to sandy-thin deposits m and the unfractured bedrock. We show evidence that the flat slab dehydrates within the mantle sosmique, but also along the subducting ridge prior to re-subducting.

Marianne Marot 1 AuthorId: Scientific congresses and symposiums: Thursday, March 13, – 5: Thursday, December 12, – 1: We show the most complete regional 3-D seismic tomography images of this region, whereby, in comparison to previous studies, we use 1 a much larger seismic dataset compiled from several short-term seismic catalogs, 2 a much denser seismic station network which enables us to resolve better the subduction zone.

We present a parallel application for seismi c ray-tracing and its exploitation on tkmographie experimental computational grid built over the Renater n twork. From a hydrogeological point of view, downstream of the study area, the alluvial plain would constitute an important aquifer with a high porosity and thick deposits.
