| Recent fieldwork strongly indicates that these crinoidal deposits should be considered a discrete unit. |
|
| Bajocian rocks exhibit great variation and include coral reef limestones, oolitic deposits, and crinoidal limestones. |
|
| Area 3: This area contains the Livingstone crinoidal limestones with some interbedded dolomitic limestone. |
|
| Area 3: Post-depositional diagenetic processes limit reservoir development by altering the primary porosity in the crinoidal limestone. |
|
| Area 2: Post-depositional diagenetic processes controlled reservoir development as sub-aerial exposure of crinoidal limestone occurred. |
|
| The Haight Creek is primarily composed of dolomitic mudstones and wackestones with abundant chert interbeds and thin, discontinuous crinoidal packstones. |
|
| The echinoderms appear to be particularly abundant in an interval up to 0.5 m below a 25-30 cm ledge-forming crinoidal grainstone with small micritic bioherms. |
|
| The Mount Head dolomitic limestones and southern Livingston crinoidal limestones also contribute reservoir development in this area. |
|
| In addition to the crinoidal limestones, oolitic limestones and lime mudstones also formed in shallow-water marine environments of the Mississippian. |
