Stratigraphy
Formation:Upper Bringewood
Stratigraphic resolution:formation
Stratigraphy comments: Especially upper two-thirds. Authors give age simply as Ludlow. Assignment to Gorstian based on correlation chart in ref. 6658.
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.
