Abstract Pollen analytical investigations have been carried out on the sediments of five profiles from a former lake exposed at the Kärlich clay-pit, Middle Rhine region, of Germany, with the aim of clarifying the stratigraphic position of the Kärlich Interglacial (Middle Pleistocene) within the European Pleistocene. The pollen sequence starts with a QM (Quercetum mixtum) phase followed by a Carpinus phase. After the interglacial period there are oscillations (Mühlheim I and II Stadials, and the Kettig Interstadial) and the sequence ends with a cold steppe phase. Parallel with these developments, conditions in the lake changed from meso- to eutrophic and back again to meso-oligotrophic. The lake was finally filled in by silty and organic sediments and then covered by loessic material, with evidence for oscillations between limnic and telmatic phases. Numerous macrofossil remains in the interglacial sediments allowed reconstruction of plant communities mainly from the lake itself, but also from the surrounding forests. The pollen analytical results indicate a warm stage that belongs to the Cromerian Complex. That is corroborated by a good conformity with the upper part of the Cromerian interglacial (Rhume Interglacial) from Bilshausen, Lower Saxony, Germany, which is considered to belong to the youngest part of the Cromerian Complex. 40Ar/39Ar laser dates of the Brockentuff (396±20 ka), a basaltic tephra deposited during the early QM phase of the same warm stage, enable the interglacial sequence to be correlated with oxygen isotope stage 11. On account of biostratigraphic arguments and old-palaeolithic artefacts within the interglacial sediments, the Kärlich Interglacial is considered to have its stratigraphical position between the Cromerian IV (based on the Dutch stratigraphy) and the Holsteinian sensu stricto.
