==Cycle order from thickness and areal extent==

Because rates of sediment accumulation and areas of accommodation space vary, thickness and areal extent are of little use in establishing the order of depositional cycles. Most cycle hierarchies are based on duration. Establishing the duration of a sequence is difficult because of problems in high-resolution dating of rocks. However, with careful work an estimate can be made (see .<ref name=ch04r67>Miall, A., D., 1994, Paleocene 16: [[sequence stratigraphy]] and chronostratigraphy—problems of definition and precision in correlation, and their implications for global eustasy: Geoscience Canada, vol. 21, no. 1, p. 1–26.</ref><ref name=ch04r7>Armentrout, J., M., 1991, Paleontological constraints on depositional [[modeling]]: examples of integration of biostratigraphy and seismic stratigraphy, Pliocene–Pleistocene, Gulf of Mexico, in Weimer, P., Link, M., H., eds., Seismic Facies and Sedimentary Processes of Submarine Fans and Turbidite Systems: New York, Springer-Verlag, p. 137–170.</ref><ref name=ch04r9>Armentrout, J., M., 1996, High-resolution sequence biostratigraphy: examples from the Gulf of Mexico Plio–Pleistocene, in Howell, J., Aiken, J., eds., High Resolution [[Sequence stratigraphy]]: Innovations and Applications: The Geological Society of London Special Publication 104, p. 65–86.</ref>
