The degree of roundness of sand grains, comprising relatively insoluble minerals such as quartz and feldspar, within a specific size range increases with the distance of eolian transport. Roundness indices based on visual recognition and counting of four grain types were used to study sands from the Alfold in Hungary and the Great Sand Hills in Saskatchewan. The Saskatchewan sand showed a significant increase in roundness within about five miles. All the sands in the sand plateau of the Alfold are eolian and increase in roundness with the distance from their source (the Duna (Danube) Valley).
