==Highstand systems tracts==

The highstand systems tract is between the maximum flooding surface and the overlying sequence boundary. Highstand systems tracts show a progradational stacking pattern due to sediment supply exceeding the accommodation space. Progradation results in basinward downlapping onto the maximum flooding surface. Basin centers may still be sediment starved if shelves are broad. Coastal depositional systems tend to be wave to fluvially dominated, thin, and widespread. Definition and further discussion on identifying characteristics of each of the surface types and systems tracts can be found in Posamentier and Vail,<ref name=ch04r79 />), Loutit et al.<ref name=ch04r59>Loutit, T., S., Hardenbol, J., Vail, P., R., Baum, G., R., 1988, Condensed sections: the key to age determination and correlation of continental margin sequences: SEPM Special Publication 42, p. 183–213.</ref> Van Wagoner et al.<ref name=ch04r70>Mitchum, R., M., Jr., Van Wagoner, J., C., 1990, High-frequency sequences and eustatic cycles in the Gulf of Mexico basin: Proceedings, Gulf Coast Section SEPM 11th Annual Research conference, p. 257–267.</ref> and Armentrout.<ref name=ch04r7 /> <ref name=ch04r15>Armentrout, J., M., Malacek, S., J., Mathur, V., R., Neuder, G., L., Ragan, G., M., 1996, Intraslope basin reservoirs deposited by gravity-driven processes: south Ship Shoal and Ewing Banks areas, offshore Louisiana, in Pacht, J., A., Sheriff, R., E., Perkins, B., F., eds., Stratigraphic Analysis: Utilizing Advanced Geophysical, Wireline, and Borehole Technology for Petroleum Exploration and Production: Proceedings, Gulf Coast Section SEPM 17th Annual Research conference, p. 7–18.</ref>
