Accretionary wedge systems are an important geodynamic feature at plate boundaries. However, the influence of parameters such as velocity of colliding plates and sedimentation rates on the formation of these systems is not well understood. Furthermore, the dependence of the type of mass flow in accretionary wedge systems and their evolution at depth on such parameters is not clear yet. Therefore, we propose a symposium the target of which is to gain a better understanding of these systems. The proposed interdisciplinary symposium should address petrologists, structural geologists, sedimentologists as well as geophysicists who study recent as well as fossil accretionary wedge systems all over the world. These studies should include various aspects of the top to the bottom features of these systems as well as modelling attempts.
