Sequence stratigraphy is a branch of geology that attempts to link relative sea-level changes to sedimentary deposits. The essence of the method is mapping of strata based on identification of time lines, such as unconformities, maximum flooding surfaces and transgression surfaces. In doing so it places stratigraphy in chronostratigraphic framework.

The key concept in sequence stratigraphy is accommodation space, the amount of space available for sediment to be deposited in. This is a function of eustatic sea level change, tectonic changes and sediment supply.
