<p>This article presents the results of studies on aeolian processes in the Oświęcim Basin in southern Poland. There are only a few large dunes in the western part (Woszczyce area) of the vast area of the Basin (about 1800 km2), and several dozen small forms (1–3 m high) in the central part (Świerczyniec area) All these forms are located on the outwash plain from the Odra Glaciation – dunes in the proximal part of sandur and small forms in the distal part. Grain size indices were determined for all samples taken at 17 sites, and quartz grain abrasion was examined using mechanical graniformametric and morphoscopic methods. The study found that the fluvioglacial deposits are not very diverse in grain size but significantly differentiated in terms of the degree of aeolization. In the proximal part of the outwash plain, deposits are characterized by very poor abrasion of quartz grains, two-three times worse than those from the distal part. Aeolian sands, in terms of grain size, do not differ essentially from fluvioglacial deposits, and in the distal part of sandur, there are no differences in the abrasion of the quartz grains. Conversely, in the proximal part, there was a significant increase in the degree of aeolization of the dune deposits compared to the source fluvioglacial deposits.</p>
