Twenty paleogeographic maps are presented for Middle Eocene (Lutetian) to Late Pliocene times according to the stratigraphical data given in the companion paper by Berger et al. this volume. Following a first lacustrine-continental sedimentation during the Middle Eocene, two and locally three Rupelian transgressive events were identified with the first corresponding with the Early Rupelian Middle Pechelbronn beds and the second and third with the Late Rupelian ( Serie Grise ) (Fischschiefer and equivalents). During the Early Rupelian (Middle Pechelbronn beds), a connection between North Sea and URG is clearly demonstrated, but a general connection between North Sea, URG and Paratethys, via the Alpine sea, is proposed, but not proved, during the late Rupelian. Whereas in the southern URG, a major hiatus spans Early Aquitanian to Pliocene times, Early and Middle Miocene marine, brackish and freshwater facies occur in the northern URG and in the Molasse Basin (OMM, OSM); however, no marine connections between these basins could be demonstrated during this time. After the deposition of the molasse series, a very complex drainage pattern developed during the Late Miocene and Pliocene, with a clear connection to the Bresse Graben during the Piacenzian (Sundgau gravels). During the Late Miocene, Pliocene and Quaternary sedimentation persisted in the northern URG with hardly any interruptions. The present drainage pattern of the Rhine river (from Alpine area to the lower Rhine Embayment) was not established before the Early Pleistocene.
We present a general stratigraphic synthesis for the Upper Rhine Graben (URG) and the Swiss Molasse Basin (SMB) from Eocene to Pliocene times. The stratigraphic data were compiled both from literature and from research carried out by the authors during the past 6 years ; an index of the stratigraphically most important localitites is provided. We distinguish 14 geographical areas from the Helvetic domain in the South to the Hanau Basin in the North. For each geographical area, we give a synthesis of the biostratigraphy, lithofacies, and chronostratigraphic ranges. The relationships between this stratigraphic record and the global sea-level changes are generally disturbed by the geodynamic (e.g., subsidence) evolution of the basins. However, global sea-level changes probably affected the dynamic of transgression-regression in the URG (e.g., Middle Pechelbronn Beds and Serie Grise corresponding with sea-level rise between Ru1/Ru2 and Ru2/Ru3 sequences, respectively) as well as in the Molasse basin (regression of the UMM corresponding with the sea-level drop at the Ch1 sequence). The URGENT-project (Upper Rhine Graben evolution and neotectonics) provided an unique opportunity to carry out and present this synthesis. Discussions with scientists addressing sedimentology, tectonics, geophysics and geochemistry permitted the comparison of the sedimentary history and stratigraphy of the basin with processes controlling its geodynamic evolution. Data presented here back up the palaeogeographic reconstructions presented in a companion paper by the same authors (see Berger et al. in Int J Earth Sci 2005).
Sedimentologie und Biostratigraphie im Rupelium der Ziegeleigrube Jungk, W611stein (Mainzer Becken) Mit 2 Abbildungen, 3 Tabellen und 6 Tafeln KIRSTEN I. GRIMM, ANGELIKA KOTHE 8 91 MATTHIAS C. GRIMM KurzfassungIn der Ziegeleigrube Jungk in W6Ilstein wurde ein Profil aus der Bodenheim-und der Stadecken-Formation (Oligozfin, Rupelium) sedimentologisch und biostratigraphisch mit Hilfe von Foraminiferen, Dinozysten und kalkigem Nannoplankton untersucht. In dem Profil ist eine Coarsening-upward bzw. Shallowing-upward Sequenz erkennbar, die mit pelitischen Ablagerungen unter der Wellenbasis beginnt und mit flachmarinen siltig-sandigen Ablagerungen endet. Okologische Aussagen sind nur eingeschrfinkt m6glich. Die Diversitiit der autochthonen Fauna und Flora ist ge¡ und zeugt von ungª Lebensbedingungen. Wfihrend der Ablagerungszeit der Rosenberg-Subformation herrschten vollmarine Bedingungen bei einer Wassertiefe von mindestens 60 m und schwer besiedelbaren Bodenverh~iltnissen. Wfihrend der Ablagerungszeit der Pfadberg-Subformation bestanden brackische Verh~iltnisse mit episodischen Str6mungseinflª in ver¡ Wassertiefe. Wiihrend der Ablagerungszeit der Elsheim-Subformation verflachte sich der Ablagerungsraum bis auf wenige Meter Wassertiefe. Das Milieu war weitgehend wieder normal marin.Die Sedimente fª bei allen drei untersuchten Mikrofossilgruppen einen hohen Anteil an umgelagerten Formen (Jura bis Eoz~n), wobei aufgrund der regionalen Geologie angenommen werden muss, dass der Transport ª einige 100 km erfolgte. Hinweise, ob das umgelagerte Material aus dem Norden oder Sª stammt, liegen nicht vor. Die autochthonen Anteile der untersuchten Mikrofossilgruppen ergaben eine Einstufung des Profils in die Globigerinidae-Miliolidae-H~iufigkeitszone, in die Dinozystenzone D14na und in die Kalknannoplanktonzone NP 24. Die Korrelation der Zonen D14na und NP24 weicht von den Kenntnissen aus Norddeutschland ab, wo die Zone D14na mit der Zone NP23 korreliert. M6glicherweise beruht diese Diskrepanz ebenfalls auf Umlagerung. Abstract[Sedimentology and biostratigraphy in the Rupelian of the clay pit Jungk, W611stein (Mainz Basin] -An outcrop of the Bodenheim-and Stadecken-Formation (Rupelian, Oligocene) was studied sedimentologically and biostratigraphically in the clay pit Jungk near W611stein regarding foraminifers, dinocysts and calcareous nannoplankton. A coarsening-and shallowing-upward sequence was identified. Sedimentation started with pelitic sediments, deposited below the wave base and ended with shallow marine, silty to sandy sediments. Ecological interpretations are limited. The diversity of the authochthonous fauna and flora is low and shows poor life conditions. The Rosenberg-Member of the Bodenheim-Formation was formed in a normal marine environment in at least 60 m water depth under soft to soupground conditions. The overlaying Pfadberg-Member was deposited in the transition zone in a brackish environment. During
