    Description / Table of Contents: Seit dem späten Pliozän / frühen Pleistozän stellt der Rhein als einer der größten europäischen Flüsse das einzige Entwässerungssystem dar, welches die Alpen mit der Nordsee verbindet. Auf seinem Verlauf von den Alpen bis hin zum Ärmelkanal passiert er unterschiedliche geomorphologische und geologische Einheiten, von denen der Oberrheingraben die Hauptsedimentfalle bildet. Während die alpinen Vorlandbecken aufgrund der hohen Dynamik des Gesamtsystems nur ein geringes Erhaltungspotenzial hinsichtlich der Sedimentablagerung aufweisen, und das Ablagerungsgebiet unmittelbar an der Nordseeküste mehrfach signifikant durch pleistozäne Meeresspiegelschwankungen beeinflusst wurde, bietet die andauernde Subsidenz des Oberrheingrabens einmalige Bedingungen für die kontinuierliche Akkumulation von Sedimenten. Die beiden größten Sedimentfallen sind dabei das Geiswasser Becken im südlichen Teil sowie das Heidelberger Becken im Nordosten. Generell nimmt die mittlere Korngröße der im Oberrheingraben abgelagerten alpinen Sedimente von Süden nach Norden ab. Das Heidelberger Becken fungiert als distale Falle im Oberrheingraben für alpine Sedimente, die durch den Rhein Richtung Norden transportiert werden. Hier ist die kontinuierliche Ablagerung von Sedimenten weniger stark durch Diskontinuitäten gestört als im südlichen Teil des Rheingrabens. Daher stellt das Heidelberger Becken eine Schlüsselposition für das Verständnis der glazialen Entwicklung der Alpen seit dem späten Pliozän und darüber hinaus für einen Vergleich mit der glazialen Entwicklung Nordeuropas dar (ELLWANGER et al. 2005).

    Description: Cores from several boreholes in the Ludwigshafen area were analysed to investigate their sedimentology, palynology, palaeomagnetics, rock magnetics and heavy mineral composition. The preliminary results are presented from the new Ludwigshafen-Parkinsel borehole P35, which was drilled 500 m WSW of borehole P34, to a total depth of 300 m. Correlation between the two boreholes reveals similarities and dissimilarities in stratigraphy, structure and the thickness of the sediments. As a result of core documentation and the preliminary evaluation of the investigation results, a good correlation is established between the coarse and fi ne-grained sequences in both boreholes down to a depth of 122 m. However, the Plio-Pleistocene boundary in borehole P35 is much deeper than in P34. A fault throw of 42 m is assumed, attributable to young tectonics. The poor correlation between the thicknesses of the sediments in the lower sections of the two boreholes suggests that tectonism was particularly active in the Pliocene and Lower Pleistocene. The different occurrence of interglacial sequences in the two Ludwigshafen boreholes can be attributed to fl uvial dynamics and neotectonic events. Further palynological analysis is required to determine whether the alternation of at least fi ve interglacial periods determined in the Ludwigshafen-Parkinsel P34 borehole, can also be confi rmed in the P35 borehole. The information gained so far from the correlation of the already analysed Middle Pleistocene interglacials in the Ludwigshafen/Mannheim area, as well as the links with the primarily Lower Pleistocene sections in Schifferstadt, already suggest that this would allow a much better understanding of the changes in vegetation and climate during the Pleistocene.

    Description: Since Late Pliocene / Early Pleistocene, the River Rhine, as one of the largest European rivers, has acted as the only drainage system that connected the Alps with Northern Europe, especially the North Sea. Along its course from the Alps to the English Channel the river passes several geomorphological and geological units, of which the Upper Rhine Graben acts as the major sediment trap. Whereas the potential of sediment preservation of the alpine foreland basins is low due to the high dynamics of the system, and the area of deposition close to the North Sea was significantly affected several times by Pleistocene sea level changes, the ongoing subsidence of the Upper Rhine Graben offers a unique potential for a continuous sediment accumulation and preservation.

    Description: The infrared radiofluorescence (IR-RF) dating technique was applied to eight fluvial samples that were collected from two sediment cores at the Heidelberg Basin located near Viernheim and Ludwigshafen in southwest Germany. Based on the IR-RF derived ages of the samples it was possible to establish a chronological framework for the Mid-Pleistocene fluvial deposits of the Heidelberg Basin. The results allow us to distinguish between four main periods of aggradation. The lowermost sample taken from 100 m core depth lead to an IR-RF age of 643 ± 28 ka pointing to a Cromerian period of aggradation (OIS 17–16). For the Elsterian it is now possible to distinguish between two aggradation periods, one occurring during the Lower Elsterian period (OIS 15) and a second during the Upper Elsterian period (OIS 12–11). For the so called Upper interlayer (or “Oberer Zwischenhorizont” — a layer of organic-rich and finer-grained deposits), the IR-RF results point to a deposition age of around 300 ka, with samples taken directly on top and out of this layer yielding IR-RF ages of 288 ± 19 ka and 302 ± 19 ka, respectively. Hence, the measured IR-RF ages clearly point to a deposition during the Lower Saalian period (OIS 9–8) whereas earlier studies assumed a Cromerian age for the sediments of the Upper Interlayer based on pollen records and also mollusc fauna. The new IR-RF dataset indicates that significant hiatuses are present within the fluvial sediment successions. In particular the Eemian and Upper Saalian deposits are missing in this part of the northern Upper Rhine Graben, as the 300 ka deposits are directly overlain by Weichselian fluvial sediments. It is obvious that time periods of increased fluvial aggradation were interrupted by time periods of almost no aggradation or erosion which should have been mainly triggered by phases of increased and decreased subsidence of the Heidelberg Basin.

    Description: In the area of Ludwigshafen (Germany; Upper Rhine Graben (URG); Fig. 1) we sampled a core (P34) which was recovered during the exploration for groundwater resources. The core comprises 300 m of Quaternary and Tertiary sediments (Fig. 2). Rockmagnetic parameters measured are: NRM (natural remanent magnetization); characteristic remanent magnetization (ChRM, could be isolated using demagnetization experiments (alternating field and thermal) Fig. 3); magnetic susceptibility measured on core and discrete samples compared with interpretation of polarity (Fig. 5); as demonstrated in figure 6, a clear correlation of heavy mineral data (Hagedorn & Boenigk, 2008; doi:10.1016/j.quascirev.2005.01.018) and susceptibility data is apparent; the so-called S-ratio (Fig. 7a) gives us information about the relative amounts of high-coercivity ('hard') to low-coercivity ('soft') remanence and therefore a fair estimate of the importance of antiferromagnetics (goethite, hematite) versus ferrimagnetics (soft magnetite, iron-sulphides); "saturation"IRM curves (Fig. 7b, c) also show a clear subdivision in soft (above 177 m) and hard (below 177 m) remanence carriers; thermal demagnetization of "S"IRM identifies greigite or (Ti) -magnetite (Fig. 8a) for the upper (alpine influenced) part of the drill whereas the lower Pliocene part is dominated by greigite (Fig. 8b); alternating field (AF) demagnetization of samples from the upper part often show acquisition of significant gyroremanent magnetization (Fig. 10a), a typical property of greigite (Snowball, 1997; doi:10.1111/j.1365-246X.1997.tb04498.x); we used a technique after Van Velzen and Zijderfeld (1992; doi:10.1111/j.1365-246X.1992.tb00715.x) detecting greigite instead of pyrrhotite (Fig. 10b); Combination of different parameters in biplots can help to separate various magnetic components (Fig. 11 a+b). We applied this method by combining anhysteretic remanent magnetization (ARM) and IRM measurements in different ways. ARM against IRM (Fig. 11a) demonstrates high concentration differences for samples from the upper part (above 177 m) of the profile and narrow plotting (low concentration variations) for samples of the lower part (below 177 m); A similar plot, the relation of ARM normalized by IRM and ARM, emphasizes this result (Fig. 11b). Again, two different clusters (high coercivity mineral (goethite) in the lower and low coercivity mineral (greigite) in the upper part of the profile) are obvious (with the exception of some samples in a mixed zone).

    Description: Im Raum Ludwigshafen wurden mehrere Kernbohrungen sedimentologisch, palynologisch, paläomagnetisch, gesteinsmagnetisch und schwermineralogisch untersucht. Erste Ergebnisse der neuen Bohrung Ludwigshafen-Parkinsel P35 werden vorgestellt, die 500 m WSW der Bohrung P34 bis 300 m abgeteuft wurde. Die Gegenüberstellung beider Bohrungen zeigt Übereinstimmungen, aber auch Unterschiede im Aufbau, Struktur und Mächtigkeit der Sedimente. Nach der Bohrkerndokumentation und ersten Auswertungen von Untersuchungsergebnissen lassen sich die grob- und feinkörnigen Sequenzen aus beiden Bohrungen bis in eine Teufe von 122 m gut miteinander korrelieren. Allerdings liegt die Plio-/Pleistozängrenze in der Bohrung P35 deutlich tiefer. Wahrscheinlich ist ein Versatzbetrag von 42 m anzunehmen, der auf junge Tektonik zurückzuführen ist. Die geringe Übereinstimmung der Mächtigkeiten in den tieferen Abschnitten der Bohrungen lässt vermuten, dass die Tektonik besonders im Pliozän und Unterpleistozän aktiv war. Die unterschiedliche Präsenz von warmzeitlichen Sequenzen in den beiden Ludwigshafener Bohrungen kann auf fluviale Dynamik und neotektonische Ereignisse zurückgeführt werden. Ob die in der Bohrung Ludwigshafen Parkinsel P34 erfassten Wechsel von mindestens 5 Warmzeiten auch in der Bohrung P35 bestätigt werden können, bleibt weiteren palynologischen Untersuchungen vorbehalten. Schon jetzt lässt die Korrelation zwischen den bereits bearbeiteten mittelpleistozänen Warmzeiten im Raum Ludwigshafen/Mannheim sowie die Verknüpfung mit den überwiegend altpleistozänen Abschnitten von der pleistozänen Vegetations- und Klimaentwicklung erwarten.
