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.
Figures & Tables
Miocene carbonates are intensively explored and locally exploited for hydrocarbons in parts of the Mediterranean regions. The outcrop models presented in this publication provide excellent analogs for the highly productive Miocene carbonates from Iran, Iraq and Gulf of Suez and for smaller reservoirs in other localities. Lessons learned in the outcrops of the Mediterranean regions are applicable as well to Miocene carbonate reservoirs. The Miocene outcrops in Mediterranean regions can serve as models for the relationships between carbonate reservoirs, pre-evaporitic basinal sediments, and overlying evaporites. Additionally, the Miocene carbonate rocks exposed in the Mediterranean regions serve as important analogs for ancient carbonate-rimmed basins with or without basinal evaporites.
