Reef belt with numerous individual reefs.
Thickness 80-250 m.
Stromatoporoids, tabulate corals (Heliolites, Thamnopora, Favosites, Alveolites, Cladopora) and rugose corals as reef builders.
Four different paleogeographic settings discussed. Not decided.
Stromatoporoids dominant. Thamnopora important in relatively quiet water settings.
Age unclear. 
Probable potential as reservoir.
Reef cited as example for succession in Walker and Alberstadt (1975).
