First thermoluminescence (TL) datings of glacial deposits from several well-known sites in northwest Germany (Schleswig-Holstein) indicate a possible Middle Weichselian Glaciation in this region. The TL dates obtained imply an ice sheet at about 70-40 ka B.P. here, whose presence in this part of Europe has not been previously considered. The reliability of the TL dates was cross-checked on different lithologies; the dating was performed in two independent laboratories. These dates and their interpretations, however, must still be confirmed both geologically and paleontologically on suitable sites where glacial sediments are sandwiched between Eemian deposits and interstadial deposits older than the Late Weichselian.

A refined sample processing technique using glacial acetic acid has been applied to Upper Cenomanian and Lower Turonian limestones from Baddeckenstedt (Lower Saxony) enabeling the first quantitative analysis of planktonic foraminiferal populations through the Stage boundary succession in northwestern Germany. Measurements of carbonate contents, organic carbon and stable carbon and oxygen isotopes were also reported. These data allow a correlation to be made of the Baddeckenstedt section with those at Misburg (basinal facies, northwestern Germany) and Dover (Plenus Marls, southern England). Significant maxima of the organic carbon content at Baddeckenstedt correspond to prominent black shale couplets at Misburg. The planktonic foraminiferal generic groups show at Baddeckenstedt similar fluctuations as reported from Dover. Their correlation reveals details of a complex paleoceanographic regime in the NW-German Basin during the Cenomanian/Turonian Oceanic Anoxic Event.
