Barrier reef with calcareous sponges, hydrozoans, Archaeolithoporella, Tubiphytes and bryozoans as main reef builders.
Microbial elements are important

Comment from Tian & Wang, 2021:
Reef builders: Frame-building and baffling
organisms: hypercalcified sphinctozoan and inozoan sponges, sclerosponges, stromatoporoid sponge, bryozoans, and hydrozoans.
Binding organisms: Archaeolithoporella, Palaeoaplysina, Tubiphytes, and cyanobacteria.

reef dwellers: 
Echinoderms, ammonites, bivalves, brachiopods, gastropods, benthic foraminifera, calcareous algae, and single rugose corals.

Rock type and reef-related depositional characteristic:
Fore-reef slope: spiculitic-calcispherical cherty wackestone with reef breccias Reef core: sponge framestone and bafflestone, Archaeolithoporella and cyanobacteria bindstone, and sponge framestone with the encrusting Archaeolithoporella
Reef flat (reef crest): packstone with reef breccia
Reef base: echinodermal packstone to grainstone
Back-reef lagoon: bioclastic packstone with calcareous algae, gastropods, and foraminifers.

Reef type:
Metazoan reef at the shallow carbonate platform margin
