The stratigraphie distribution of lithofacies and the occurrence of coarse ice-rafted debris (>2 mm) have been studied on three sediment cores based on x-radiograph analysis, that were recovered during RV "Polarstern" expedition ARK-XXIII/3 from different depositional settings at the eastern Mendeleev Ridge. Various mud lithofacies with generally low contents of icerafted debris dominate the lithology while diamictons are restricted to possibly middle to late Pleistocene sediments. The muds have been possibly formed by the release of fine-grained sediments from melting sea ice while the diamictons are derived from iceberg and subordinate sea-ice rafting. The rapid sedimentation of diamictons has overprinted the long-term deposition of muds indicating that sedimentation rates must have been quite variable in the diamicton-bearing lithological Unit I of STEIN et al. (2010b). The lithofacies distribution has been compared with wet bulk density, p-wave velocity and magnetic susceptibility data of the sediment cores revealing a correlation of some lithofacies with the physical properties of sediments. The diamictons are characterized by maxima in wet bulk density and p-wave velocity showing that they may form distinct acoustic reflections in seismic records that are potentially useful for correlation of sediment cores recovered during ARK-XXIII/3. There is not a unique correlation between sediment colours and lithofacies. However, brown colours are mainly confined to bioturbated muds in sediment cores PS72/392-5 and PS72/396-5, while diamictons have usually light colours. In sediment core PS72/340-5 from the East Siberian continental margin, brown colours occur both in bioturbated muds and diamictons while laminated muds are always greyish.
