The AA. demonstrate how combining high-resolution grain size and microscopic analyses can be used to discriminate depositional and pedogenetic features of Late Pleistocene loess-paleosol sequences (LPS) from the Saxonian Loess Region. Grain size analysis was conducted by classical pipette and sieve procedures and 8 grain size classes were distinguished. Generally, it was observed that an increase of coarse material is linked to an increase of the minerogenic components which can be attributed to slope surface processes. When studying coarse grain size fractions by microscopic analysis, it is possible to differentiate between loessic layers formed by periglacial slope processes and layers overprinted by pedogenetic processes based on determining the nature and roundness of minerals. The results reveal similar temporal and lithogenetic pattern of Weichselian eolian dynamics of the study area and other records from the European continent. Furthermore, lithogenetic interpretations based on grain size analysis conform to found age ranges obtained by Optical Stimulated Luminescence (OSL) dating
