Lithology and environment
| Primary lithology: | "limestone" |
| Secondary lithology: | conglomerate |
| Lithology description: conglomerate and sandstone at its base, grading upwards into fossil rich limestone | |
| Environment: | shallow subtidal indet. |
| Geology comments: This formation is mainly composed of conglomerate and sandstone at its base,
grading upwards into fossil rich limestone in its middle part, and sandstone at the top, indicating a varying water depth. The corals are found in the limestone. | |
