This session addresses the dynamics of sedimentary basins on different scales and aims to bring together studies focussing on geodynamics, tectonics, sedimentology / palaeontology, and geochemistry.The Task Force Sedimentary Basins of the International Lithosphere Programme promotes the dialogue between researchers studying the basin fill with those investigating the deeper structure as well as with those developing numerical and analogue experiments of processes that take place in basins of different geo-tectonic settings. This session therefore is ment as a platform for this type of exchange and wants to combine basin-fill related research with concepts of deep lithospheric deformation and to evaluate the relationship between the two end members. We seek contributions integrating data from different depth levels of the lithosphere as deep seismic sounding and analysis of the potential fields with observations from the shallower parts of the basin system as subsidence pattern, stress, vertical motions and active faulting.We welcome contributions analyzing the interactions between deep earth and surface processes, i.e., thermicity, phase-transitions, fluid circulations and transfers, fluid-rock interactions, interactions between tectonics, erosion, sedimentation and climate. Furthermore studies yielding constraints on the variety of conceptual and quantitative models explaining the origin and evolution of basins in different tectonic settings are invited. The record of basins, in contrast to mountain belts, represents the archive of their dynamic history. In addition, they provide long term geothermal reactors when sediments are brought to greater depth, under high pressure and temperature conditions. At the same time, understanding the long term interplay between processes affecting the lithosphere and crust and their interaction with the sediment fill is required. Salt, a common component in basins, may act as a decoupling layer or even may develop its own dynamics. Fluids may be generated and/or mobilised and then change the physical properties of the sediment fill. And, of course, many basins, even some rather old ones, are still evolving, providing the link to neo-tectonics and actual human problems.
