TS4.3Sedimentary basins and the geodynamic record (co-organized)
|Convener: Christian Heine | Co-Convener: Judith Bott|
Sedimentary basins provide rich archives to understand and quantify the responses of complex, multi-scale tectonic processes shaping the Earth. The session aims to address the processes modulating the evolution of sedimentary basins after their formation, such as dynamic topography induced by mantle convection, lithosphere dynamics, lithosphere/asthenosphere interactions, melting, responses to changes in the stress field and plate tectonic configuration, as well as responses to hinterland tectonics. The study of sedimentary basins and their relation to geodynamic processes involves both data analysis at different scales and using different methods as well as physical process models ranging from dislocation scale to global scale. We therefore hope to stimulate this interdisciplinary field of study by inviting contributions that adress some of the following topics:
- The analysis of the sedimentary record in terms of vertical motions and tilting induced by mantle dynamics (e.g. in intracratonic basins).
- Studies analyzing and quantifying the contribution of lithosphere/asthenosphere-scale dynamics (e.g. small scale convection) on basin infill and thermal evolution.
- Evolution of the sedimentary routing system in response to geodynamic processes.
- The sediment archive as record of hinterland tectonics (e.g. in foreland basins).
- Responses of the structural inventory to an evolving stress field and different plate tectonic configurations.
- The causes and effects of multiple rifting/reactivation in sedimentary basins.
- Effects of melting on basin evolution, differences in the evolution of volcanic and nonvolcanic marginal basins.
- Innovative, fresh approaches using cutting-edge data or technology.
