CM patterns are a means for analyzing transportation mechanisms and determining the mechanisms that form peculiar deposits, such as stratigraphic traps.Turbidites and certain tractive current deposits have several common characteristics. Their texture shows that they may have a common origin as wave suspensions.The many applications of grain size analyses indicate that they are a versatile means of investigationthat discloses the orderly arrangement of a number of geological factors. This order is a fertile field for geological re- search,
