| Abstract: | In this paper, statistical analysis is made on different calculating methods for grain-size parameters of Quaternary sediments from South Yellow Sea. The compared calculating methods are: (1) method of Folk and Ward (1957); (2) method of standard of marine survey (1975) and (3) method of moment measures. The compared grain-size parameters are average (or median) values and sorting coefficients. The comparison is respectively done on the environments such as shallow sea, tidel bank, shore, river mouth, river, lake and swamp, and on sediment types such as sand, silty sand, sandy silt, silt and clayey silt. The results indicate that data calculated from the three methods are highly correlable and can be used in intercorrelation of regression equation. |
