Schematic illustration of Pleistocene sequence stacking patterns (modified from Allen and Chambers, 1998) shows delta progradation was continuous during relative sea-level fall, so that the sand deposits of the highstand and early lowstand systems tracts are attached; an unconformity separates the early and late lowstand phases. The most obvious discontinuities in this type of sequence pattern are the maximum flooding surfaces and the unconformities between the early and late lowstand.
