Learning objectives
The main concepts of lithosphere and of sub-lithospheric mantle dynamics are provided. In addition one of the main goal is the analysis of actualistic tectonic models and their application to case histories. Specific attention is given to the role of mantle convection in relation to tectonic plates dynamics, on active margin deformation, and on relationships between the thermal state of the lithosphere and the geodynamic settings. To consolidate knowledge, classroom exercises and field trips are added to the theoretical lectures, in which analytical problems characterising the structural investigation of active zones of the lithosphere at different structural levels, in extensional, transform and convergent geodynamic regimes are tackled.
In particular, learners will acquire the knowledge necessary to understand:
· Mantle convection: convection mechanism and convective structure; lithospheric plates related to mantle convection; mantle heterogeneity.
· Geodynamics and deformation of continental plates in subduction and collision zones and active tectonic erosion and accretion mechanisms. Active tectonic mechanism along divergent and transform margins, geometric and structural outline.
· Geodynamics of present day oceanic lithosphere and of ophiolitic complexes (examples from the Alps; P-T trajectories).
· Thermal state of the lithosphere in the mechanically active zones (subduction, collision, rift): thermal models analysis and comparison with the thermo-mechanical evolution of collisional belts (Alps, Variscan chain, .....) or of fossils and present-day continental rifting.
Expected learning outcomes
Understanding of the relationships between thermal and mechanical perturbations of lithosphere and sub-lithospheric mantle along the active margins. Lithostratigraphy of the oceanic and continental lithosphere in stable and mechanically active zones. Awareness of a multidisciplinary analytical approach that involves the integration of natural field and laboratory data with quantitative geodynamic modeling techniques for the reconstruction of the tectonic evolution of complex areas such as collisional chains.
