| Abstract: | The interpretation of microfacial and geochemical sediment features resulted in a detailed sequence analysis of Upper Muschelkalk strata in the northern and middle parts of West-Germany. It is now possible to correlate columnar sections at far distances. The method allows to make a synthesis of basin evolution. In this way it also succeed to reconstruct the dynamic activities in an epicontinental sedimentation area. The Upper Muschelkalk strata shows a hierarchically nested development of stratification cycles. There are minor cycles of probably paleotectonic origin, which are only locally significant. The major cycles are basing probably on sea level changes and allow supraregional parallelizations of sections. Indicators of the sea level maximums are clay horizons. They are called »Tonhorizonte« in Southern Germany and could be proved also in the Upper Muschelkalk strata of Northern Germany. So the stratigraphic correlation of the two sedimentation areas, which were so different in paleotectonic views, is possible. |
