Abstract
Accurate field investigations and shallow seismic reflection profile i nterpretation show that forced folding and decollement of the Jurassic sedimentary cover occurred during latest Eocene times as a result of normal faulting in the basement along the master detachment fault of t he southern Rhinegraben. Consequently, the first synrift sediments exh ibit intraformational unconformities and a syncline geometry. Faulting propagates towards the surface during Oligocene times, thus controlli ng a roll-over type deformation in younger Rupelian synrift sediments.
