The aim of this field trip is study past and present geomorphologic processes in the Pyrenees and to trace sediment production and transfer from the high altitudes of the Pyrenean orogen to the river systems of the foreland basin and into the ocean sink. We focus on erosional, transport and storage processes of sediment and their geological development in the tectonic-geodynamic context. In the preparatory seminar, we will discuss relevant concepts and scientific literature.
