An industrial X-ray computed tomography (CT) system was used for the study of sedimentary and deformation structures in weakly consolidated late Pleistocene and Holocene lake sediments. CT analysis revealed details of structures that could not be detected by X-ray radiography or visual core logging. Examples include sand dykes, dropstones and plant remains, which are potentially important in palaeoseismological and palaeoenvironmental research. The CT images also help to discriminate between drill core artefacts and natural structures. X-ray tomography was also used for the determination of physical properties, particularly for bulk density measurements based on calibrated grey-scale values.
