Applied Biostratigraphy

As the rate of sea level rise increases after the stillstand/slow increase at the end of LST deposition, the continental shelf begins to be progressively submerged again as the coastline migrates back across the shelf towards the hinterland. Retrogradational parasequences develop towards the inner parts of the shelf and more distal parts of the shelf and slope experience sediment starvation and the onset of condensed sections across the slope and basin floor. Rivers are no longer necessarily confined to valleys and more floodplains develop inboard of the coastline.
