The grain-size distribution of aeolian dune sands in the Thar Desert, India was analyzed and compared with 3 model distributions – log-normal, log-hyberbolic and log-skew-Laplace – to determine the best-fit statistical model. In total, 51 samples were collected along a single transect over a transverse dune, of which 15 were from the stoss side, 12 from the crest and 24 from the lee side. Samples were collected during a calm period in the afternoon of a winter's day. Results and discussion. It is suggested that the main criteria for the development of a normal distribution is the lack of skewed fractions and the concentration of the narrow, intermediate size fractions in the final grain size distribution
