The Eocene Annot Sandstone in the French Alps corresponds to a turbiditic system up to 1000m thick, which has filled large morphologic gutters induced by tectonic activity. Detailed field studies have recently been undertaken on well-exposed 3D outcrops at a reservoir scale (kilometric), in order to analyse and reconstruct the architecture of deep-marine gravity deposits. These selected sites belong to different sedirnentary settings (inner fan valley, channel-levee system, depositional lobes) and different morphological configurations (narrow trough controlled by faulting, unconfined basin), and they exhibit a large variety of facies (slumps, debris-flows, high and low density turbidites).
