At high sedimentation rates, the shoreline will still move seawards, even though the sea level is rising. During periods when the sea level is static the addition of sediment causes the shoreline to shift seawards. At low rates of sea-level fall and/or high rates of sediment supply deposition occurs as the shoreline moves seawards.

Two contrasting hypotheses have recently been proposed for the past long-term relation between atmospheric CO2 and the carbonate-silicate geochemical cycle. One approach (Berner, 1990) suggests that CO2 levels have varied in a manner that has maintained chemical weathering and carbonate sedimentation at a steady state with respect to tectonically controlled decarbonation reactions.
