The Aquitain Basin (SW-France), the Baseo-Cantabrian Basin (N-Spain), the Pyrenees, the Provence Basin and the Voeontian Trough (SE-France), the Helvetic Zone, the Paris Basin, basins in N-Germany, the Polish Trough, the Penibetic Zone (S-Spain), the Umbria-Marche Basin (Italy), and the Atlas Basin (Tunisia) belong to the investigated structures. From the stratigraphic analysis of n sections a relative age model (Composite Standard CS72) was caleulated in using Graphic Correlation. Composite Standard CS72 is composed of 214 stratigraphic events, whieh were selected from 567 stratigraphic events in the Cenomanian-Turonian. Composite Standard CS72 was elaborated in using "Splitting Tops and Bases".197 ppdeinfo:eu-repo/semantics/openAccess550Bericht, Reporturn:nbn:de:gbv:46-ep000103201
