Solenopora-gastropod facies as pre- and inter-reef sediments. 
Reefs as a series of 2m thick isolated structures. 
Coral skeletal volume very high (90%).
Highly micritized carbonate grains, and high bioerosion through bivalves. 
Effectively monospecific buildup dominated by Thamnasteria concinna. 30-40 cm sized colonies.
