SUMMARY Careful sampling of the constituent laminae of cross‐stratified units and their subsequent mechanical analyses have revealed a rhythmic pattern of size differentiation. The cross‐strata have been analysed in terms of our existing knowledge of the mechanics of layering in granular sediments. The concept of “elementary rhythm‐unit” has been introduced and the genesis of a cross‐stratified unit has been reviewed in terms of the growth and interplay of the elementary rhythm‐unit.
