Research paper thumbnail of Seismic evidence of continental subduction and upper mantle deformation beneath the western Alps

The onset mechanism of continental subduction, including how the continental plate overwhelms the buoyancy resistance and how it is exhumed, however remains elusive. Using data of a new temporary seismic array deployed in the French-Italian Alps, we present here new evidence that in the Western Alps the European plate subducted deeply beneath the Adria plate. This study uses teleseismic P receiver functions and shear-wave splitting measurements from SKS phases. In the depth-migrated receiver function cross-section (common conversion point technique), the positive P to S (Ps) conversions (corresponding to velocity increase with depth) on the Moho interface can be continuously traced beneath the European plate. This Moho conversion fluctuates in depth, amplitude and dipping angle. Be...

Research paper thumbnail of Quantification of the sediment budget of Annecy Lake (Northwestern Alps) during a major sediment yield event of late glacial stage

A high-resolution seismic-reflection survey was realized (RCMG, University of Ghent, Belgium and ... more A high-resolution seismic-reflection survey was realized (RCMG, University of Ghent, Belgium and LGCA, Université de Savoie, France) on Annecy Lake in 1993 (nothwestern Alps, 446m a.s.l). A seismostatigraphic approach led to subdivide a 150m-thick pile (in the center of the basin) into five units (Van Rensbergen et al, 1997; Beck et al., 2001). The unit 2 (one of the basal

The chronology has been done using AMS C14 on bulk sediment; since the water-sediment interface was not recovered, the age-depth model was not constrained for the last centuries. In order to study the sediment fluxes over the last millenium linked with climate
