Messinian reefs from western Orania occur along a narrow outcrop belt which is several hundred meters wide and tens of kilometers long. The reefs show generally a sequential organization of buildups in a backstepping pattern. Each step of reef-building is represented by a tabular fringing reef with poor internal zonation. Cyclic input of argillaceous sediment produced a rythmic response in coral growth. These well-bedded reefs developed during a general lower Messinian transgressive episode.
