Lithology and environment
Primary lithology: | grainstone |
Secondary lithology: | packstone |
Lithology description: Carbonate environments of inner shelf...Limy packstone nodules up to 50 mm in length...Other limestones tabular..Ostracodes associated with grainstone lithology | |
Environment: | marine indet. |
Geology comments: carbonate inner shelf...corals and shells concentrated in cut-and-fill structures...normal wave base depth inferred from ramose and dendroid bryozoans...brachiopods disarticulated...all fossils epibenthic...environment somewhat more turbulent, well oxygenated. BA 3 but not truly rough water. |
