If the inner margin is masked by subsequent marine or continental deposition, it is evidenced by a break in slope, and the uncertainty associated to the past sea level is higher.

Reef flats are a particular type of marine terrace developed in inter-tropical environments as a result of bioconstruction as opposed to marine erosion processes that are selected according to the type of material available for dating as well as stratigraphic considerations.

Because they are relatively easily dated, marine terraces are often used as geomorphic sea level markers When the inner margin of the terrace is clearly identifiable (e.g.

Marine terraces can be shaped by marine erosion (wave-cut terraces) or can consist of shallow water to slightly emerged accumulations of materials removed by shore erosion (i.e., marine-built terraces).

This latter type is usually characterized by the presence of deposits of marine origin, which can include marine fauna.
