This block course aims at delivering participants current concepts and application of sequence stratigraphy in clastic systems with support of exceptional seismic geomorphology images of depositional environments preserved in the subsurface. The course is divided into two segments: 1) sequence stratigraphy (Jean-Loup Rubino), and 2) Seismic Geomorphology (Jacqueline Camy-Peyret). In the first part, participants will be provided by updated theory and concepts of sequence stratigraphy in siliciclastic systems. In the second part, participants will learn the geophysical background behind 3D seismic data and concentrate on the use of 3D seismic data for unraveling ancient depositional environments hidden in the subsurface. Both segments of the course offer a balance between frontal theoretical teachings (30%) and exercices and practicals (70%) with real case data as used in the industry.
