Sketch showing the effect of orbitally-driven high-frequency and short-term sea-level fluctuations superimposed on a long-term transgressive trend. Subsidence is assumed constant through time. The creation of a small-scale sequence composed of five elementary sequences is simulated. Note that the maximum-flooding interval of the small-scale sequence is situated at the end of the thickening-up trend of the elementary sequences, even if a 20-kyr sea-level cycle leads to intertidal conditions with birdseyes at its top. The resulting small-scale sequence is highly asymmetric. Legend of symbols is given in Fig. 4
