The grain size analysis of fifteen specimens from Honghuatao Formation in Dangyang area at the northwestern boundary of Jianghan Basin shows that their average diameters, sorting coefficients, skew coefficients and kurtosis coefficients are mainly in the same range, and they bear similar frequency curves of grain size with double peaks and similar probability cumulative curves with an obvious pattern of three segments. Based on this and referring to the equation of sedimentary dynamics, the comparative analysis was done by both hydrodynamic concept and aeolian force concept in this article. A conclusion was drawn that the genesis of sands in the Honghuatao Formation at the northwestern boundary of
