Abstract

One of characteristics studied in many researches on desert and arid zone such as study of ERGS, Aeolian erosion, moving of SAND DUNE, etc is GRAIN SIZE and morphoscopy. This study, as first step, is done in IRAN for recognition of many regions especially in different ERGS but, there is still a necessity of comprehensive research on IRAN ERGS and calculation of correlation among this characteristic with the others such as transition distance, sorting, etc. In this research, the mean of diameters of particles, the mean of mode of particles, the mean of skew ness in normal charts of particle diameters and the mean of distance moving of internal and coastal ERGS were compared. There were no significant differences in the mean of diameter, the mean of skew ness, the mean of distance moving in internal and coastal ERGS. But the mode of particles diameter was shown to have difference. The mean of diameter in internal ERGS is varied from 74 µ to 689 µ and in coastal ERGS is from 100 µ to 744 µ. 31% of mode of diameter in internal ERGS is classified in class of 75 µ, 63% in 150 µ, 2% in 300 µ and 4% in 600 µ. These amounts are different in coastal ERGS as 18% for class of 75 µ, 73% for 150 µ and 9% for 300 µ. The skew ness in internal ERGS is varied from -0.2 to 2.95 and in coastal ERGS from 1.31 to 2.71. The mean of moving distance has 4 classes consisting of 3, 12.5, 35, and 125 Km for internal ERGS are 4, 2, 63 and 31% and for coastal ERGS are 0, 9, 73 and 18%
