Lithology and environment
| Primary lithology: | lithified packstone |
| Secondary lithology: | lithified grainstone |
| Lithology description: The enclosing rock almost always consists of packstone or grainstone, and packstone is slightly more common than grainstone. | |
| Environment: | shallow subtidal indet. |
| Geology comments: At some of the sites, the coral heads are overturned, and at others they are aligned parallel to each other. this suggests periodic high-energy events. The prescence of common corals and echinoderms indicates normal salinity conditions. | |
