The maximum flooding surface represents the greatest transgression of shallow marine facies within a sequence.<ref name=ch04r68 /> This is typically associated with a downlap surface formed by the progradation of the overlying highstand systems tract. Not all downlap surfaces are associated with maximum flooding surfaces.
