Foreland basins archive the evolution of mountain belts, and fold-thrust belts are the linking elements between orogens and their forelands. One of the major challenges for understanding the dynamics of mountain belts is untangling the different driving mechanisms that can be responsible for exhumation of mountain belts and foreland basin deformation. In particular, the signals of plate convergence (i.e. tectonic processes), deep seated (mantle-related) processes, or climate differ with respect to their timing and spatial extent. Ensuing foreland deformation is also influenced by heterogeneity of the deforming material. For instance, stratigraphic variations of the foreland basin fill or its substrate or inherited structures add complexity to the system.

In this session we invite contributions focusing on linking mantle and crustal tectonic processes with foreland basin dynamics. This includes addressing the interplay between plate boundary forces and of inherited structures, sediment production, transport and deposition (source to sink studies), and studies constraining timing of orogen processes at different scales (ranging from short term deformation rates to longer term rates based on cosmogenic nuclides or thermochronometry). We particularly invite contributions linking geophysical with geological data including 3-D models and addressing their respective uncertainties. We encourage the presentation of field-based studies as well as analog and numerical models highlighting the link between foreland basin deformation and mountain building processes including deformation of fold-thrust belts.
