摘　　要：Tidal sand ridges are large-scale linear bottom configurations in a good many tidal seas. The modern tidal sand ridges in Jianggang area, the northern part of Jiangsu Province, China, have attracted the attention of geological circles because of the radial form and large scale. Berg, Brenner and Davies have reported that linear sand bodies of this kind were recognized within the Mesozoic strata of western America, but we have not seen any reports about the discovery of this kind of sediment from the ancient lithofacies analyses of China, especially in coal-bearing strata. Based on the study of sedimentary facies, this note describes the deposits of tidal sand ridges in the coal-bearing strata of China.
