Quartz grain surfaces from the Sahara desert and from an actual beach south of Rome were inspected by electron microscope. The results were compared with the observations on grain surfaces from a Pleistocene dune near Priverno (Latina). Morphoscopic features of the two recent samples agree with those from bibliography on the subject. Analyses on the grains from Priverno, made for the first time on geological material, allowed us to determine that they came from beach sands reworked by the wind.
