Lithology and environment
Primary lithology:hardground packstone
Includes fossils?Y
Lithology description: "This community is developed in a carbonate packstone deosited on a distal, subtidal platform."
Environment:marine indet.
Geology comments: "Most of the bush-shaped specimens are overturned, but not fragmented or abraded, indicating a slight degree of turbulence. The high diversity and marked tiering point to well-aerated conditions. The facies is succeeding and laterally surrounding a micrite bank [which] shows well-developed karst features and was therefore subaerially exposed. Consistent field observation of dip and strike show that the C. Comm. facies probably protruded slightly agove surrrounding lagoonal areas. The sediments did not accumulate around and secure the holdfasts of the taxa. This was probably a hardground community...The overturning of corals occurred during infrequent storms. The BA position ranged from inner 3 into 2."
