The reef-front facies is composed of breccia containing clasts from the reef, including intraclastic grainstone, microbial framestone, microbial boundstone, peloidal grainstone, and peloidal micrite. The reef core is developed on a sand- and pebble-sized bioclastic and intraclastic shoal that was stabilized by calcimicrobes and sparry calcite.
