Coral-stromatopore boundstones.
Almost 100 m thick
Subsurface data only.
Outer ramp reef complex. Wave resistant.
Sponges in fore reef only.

This reef complex is about 7 km wide and 70 km long, and is up to 100 m thick. A shoaling-up succession from bioclastic wackestone to coral-stromatoporoid boundstone is characteristic for this bioconstruction. The reef-frame is marked by massive-nodular, vase-shaped, and laminar coral morphotypes, encrusting and branching stromatoporoids, and green algae. Lateral facial differentiation in fore-reef slope facies and lagoonal deposits is well developed. The vertical reefal succession shows indications of shoaling-up conditions into the zone of wave action with accumulations of dicerid rudists, other molluscs, and green algae.
