Sedimentary and petrographic examinations of the brown coal coverbeds in the lower Rhine basin document an environment near the sea during the Miocene and Pliocene. Small changes in facies and fluctuation between humid and semiarid climate caused the different types of sediments. The larger relative movements (sea level / lower Rhine basin) are documented only in erosional unconformities. During the Pleistocene fluviatile sedimentation took place. The combination of tectonic movement and climatic changes determined the...
