Sedimentary basins evolve in response to lithospheric deformation and store a record of this deformation. Currently, different dynamic concepts compete in explaining the observations in basins of different geo-tectonic settings. On one side the evolution of basins is analysed based on the geometry of the basin fill, the recorded thermal history as well as the generation and evolution of fluids. Especially the search for hydrocarbons yielded remarkable breaktroughs in the understanding of sedimentary basin evolution as boundary conditions for the generation migration as well as sequestration and leakge of organic matter and related feed-back mechanisms with climate. On the other hand deep lithospheric processes are studied to unravel the controlling mechanisms of basin subsidence as magmatic injection, underplating, uniform or differential stretching, flexural or local isostatic compensation.
The main goal of this session is to bring together basin-fill related research with concepts of deep lithospheric deformation and to evaluate the relationship between the two end members. We welcome contributions analyzing the interactions between deep earth and surface processes, i.e., thermicity, 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. In addition 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.
