The aim of the study was to determine the influence of textural features of sand on aeolian transport in six designated fields in northern Sahara. An analysis of textural features such as: mineral composition, grain shape, mean grain size diameter and sorting were performed during a multi-year research on dune sediments. Information on the movement of small landforms (1.5m) in areas of similar physico-geographical environments was taken under consideration. It was revealed that the fastest movement, of about 90 my⁻¹, is characteristic for barchans on dune field no. 4. (where gypsum sand dominates). Barchans on dune field no. 1 are slower, with 50 my⁻¹ (where limestone dominates), and the slowest are those on dune field 6 (where quartz dominates), with about 30 my⁻¹. The result of the study proves that textural features have a significant influence on aeolian transport.
