ResumoThe lowlands around Leipzig and the adjoining region between the River Saale and River Elbe were a low subsiding basin from the Middle Eocene to the Middle Miocene that merged with the Tertiary basin of northern Germany in the Middle Oligocene. In addition to epirogenic subsidence, subrosive (solution) lowering resulted in complicated patterns of sedimentation. Solution along individual beds has resulted in enormous variations in the thickness of lignite in areas such as Geiseltal, the Weisse Elster Basin, and in the Lützen–Merseburg and Düben–Torgau graben. Fluvial, fluvial–limnic and organic sediments interbed with marine and marine littoral facies, and four marine transgressions can be identified in the Upper Eocene and Lower Miocene. During the Middle Oligocene, the marine transgression reached its maximum extent in eastern Germany. During the period between the Middle and Upper Oligocene, uplift of the area resulted in subaerial erosion and valley-like dissection of the older Tertiary strata. From the Upper Miocene through to the Pliocene, erosion has been dominant.
