Abstract
The investigated gravel-pit lies in the hinterland of the Pomeranian end-moraine zone. The structures in the sediment are strongly influenced during the glacier's recession. Especia11y the margins of the pit show strong deformation. Until now the sediments have been interpreted as subglacial tunnel deposits. Moreover the whole sequence is considered to be discontinuous. It has been suggested that Weichsel-2, Saale-2 and possibly Weichsel-l diamicton should occur in the outcrops. Several organic layers have earlier been identified as Eemian peats, which should divide the Weichselian from the Saalian diamicton.
According to this study the sediments in the southwestern part of the pit represents a continuous sedimentacy sequence, laid down... (More)

Several organic layers have earlier been identified as Eemian peats, which should divide the Weichselian from the Saalian diamicton.
According to this study the sediments in the southwestern part of the pit represents a continuous sedimentacy sequence, laid down during the disintegration of stagnant ice of the Pomeranian stage. The sediments consist of interbedded diamictons and fluvial sands.
The diamicton beds are interpreted as flow tills, deposited in troughs parallel to the stagnant ice margin. Thus the stacked diamicton beds does not represent several glacier advances or oscillations, as previously suggested. Since the Quarternary stratigraphy in northeastern Germany is based on borings, it has possibly to be controlled by lithostratigraphical and sedimentological principles. (Less)
Abstract (German)
Die untersuchte Kiesgrube liegt im Hinterland der pommerschen Endmoräne. Die Strukturen im Sediment sind sehr von Vorgängen beim Gletscherrückzug geprägt. Besonders die Randteile der Grube weisen starke Deformationserscheinungen auf. Bisherige Interpretationen dieser gehen auf Ablagerungen in subglazialen Rinnen ("Tiefe Grundspalten") hinaus. AuBerdem sieht man die Lagerfolge als diskontinuierlich an. Jedoch sollen sowohl Weichsel-2, Saale-2 und eventuell auch Weichsel-l-Moränen im AufschluB zu finden sein. Mehrere organische Ablagerungen sind als Eem-Torfe identifiziert worden und sollen demnach die Weichsel- von der Saale-Moräne trennen.

Die untersuchte Kiesgrube liegt im Hinterland der pommerschen Endmoräne. Die Strukturen im Sediment sind sehr von Vorgängen beim Gletscherrückzug geprägt.

Mehrere organische Ablagerungen sind als Eem-Torfe identifiziert worden und sollen demnach die Weichsel- von der Saale-Moräne trennen.
Nach den kürzlich durchgeführten Untersuchungen jedoch handelt es sich bei dem Anstehenden im südöstlichen Teil um eine kontinuierliche Lagerfolge, in der lediglich Toteissedimente vom Rückzug des Weichsel-Gletschers vertreten sind. Das gesamte Sedimentpaket besteht aus flow tills und fluviatilen Sanden. Mehrere Geschiebemergel übereinander bedeuten nicht, daB es sich unbedingt um verschiedene GletschervorstöBe oder Oszillationen handeln muB. Da die quartäre Stratigraphie im nordöstlichen Deutschland vielfach auf Bohrungen beruht, muB eventuell auch diese nach lithostratigraphischen und sedimentologischen Prinzipien korrigiert werden.
