==Procedure==

==Procedure==

To determine cycle order of a sequence of sediments, we use biostratigraphic data, stratigraphic context (i.e., what part of a systems tract the interval is from), oxygen isotope curves, and published sea level curves. The table below suggests a procedure for determining cycle order of a rock sequence.

To determine cycle order of a sequence of sediments, we use biostratigraphic data, stratigraphic context (i.e., what part of a systems tract the interval is from), oxygen isotope curves, and published sea level curves. The list below suggests a procedure for determining cycle order of a rock sequence.

# Determine the time span during which the sequence was deposited and compare to age ranges for cycle orders (see table below).

# Determine the stratigraphic context of the sequence. What are the cycle orders for similar sequences above or below it?

# Determine the age of the sequence and compare it to published sea level cycle curves.<ref name=ch04r43>Haq, B., Hardenbol, J., Vail, P., R., 1988, Mesozoic and Cenozoic chronostratigraphy and cycles of sea-level change: SEPM Special Publication 42, p. 71–108.</ref>
