Depositional cycles can be subdivided into systems tracts, each representing a specific phase of relative sea level, e.g., highstand, falling (regressive), lowstand, and rising (transgressive). Nonmarine systems tracts can be related to rise and fall in lake level or water table level, which may or may not be synchronized with sea level change. [See Wheeler[1] for a discussion of base level.] Identifying each cycle phase of a depositional sequence and mapping the contained facies provides a paleogeographic map for a relatively short time interval. Such high-resolution maps provide useful predictions for hydrocarbon prospecting. This subsection discusses the concept of sea level cycle phase, identification of cycle phase, construction of a cycle chart, and how sea level cycles of different duration interact.
