A 3D structural model, consistent with geological and geophysical observations, integrates the sedimentary infill as well as the structure of the underlying crust and the lithospheric mantle from the continent over the severely extended continental margin to the oceanic domain. This model provides the base for reconstructions of the post-Jurassic deformation history and for the assessment of the related factors controlling temperature and pressure in the basin.
We study the controlling factors for salt movements in relation to regional deformation at passive continental margins. The planned research is part of larger research plan of our group addressing deformation mechanisms of salt-bearing basins in general. Specific controlling factors can be eliminated that are characteristically different for post-depositional mobilisation of salt at passive margins, in intra-continental basins and in foreland basins.
We analyse the polyphase deformation history of the CEBS (CEBS) and estimate the paleostress states responsible for the observed deformation by performing a field-based fault-slip analysis.
3D Gravity Modelling and Subsidence Analysis in the Orange Basin, Southwest African Continental Margin
A combined analysis of seismic, gravimetric and well data is used to reveal the tectonic evolution of the Orange Basin and to identify parameters of rifting and basin development.
