Abstract ref. 2128:
Bafflestones, framestones as well as bindstones are described. According to the function of reef-building, the organisms are classified to frame-builder, bind organisms and clastic-builder, in which main frame-builders are Sphictozoa, Inozoa, Tabulozoa and Hydrozoan, the bind organisms are Archaeolithiporella, Tubiphytes, Tabulozoa and blue-green algae. Four developing stages of the reefs have been distinguished.
