Sedimentary Structures: Active Margins

Based on fundamental geoscientific knowledge on subduction zones, we now focus on the interplay between tectonic, seismic activity and mass transport processes at active convergent margins. This module combines two main objectives: (1) to gain a deeper insight into mass transfer processes and their manifestations at active convergent margins and (2) to introduce numerical simulation techniques and to have the ability to develop numerical models for various mass transfer scenarios at continental margins.

1) broaden and deepen knowledge of deformation and mass transfer processes at convergent margins; mechanics and dynamics of forearc regions
2) geotechnical characterization of marine sediments; lab techniques and interpretation
3) familiarization with geophysical, particularly reflection seismic, data interpretation
4) introduction and overview about numerical modelling techniques
