"A quantitative study of samples from various aeolian microenvironments from the Suez Canal zone is carried out. The use of the revised method for obtaining Gaussian curves gives further information on their use. All aeolian sands fully adjusted to their depositional environment obey a logarithmic probability law. The sediments of each aeolian microenvironment are found to have different characteristics. Certain failings of earlier morphological classifications are noted."
