| Outstanding feature |
Ooids trapped & cemented within capillary crust |
| Folk Classification |
Oomicrite with high porosity |
| Dunham Classification |
Supratidal crust of ograinstone & oolitic packstone |
| Common Grains |
Oolites, and pelecypods |
| Sorting |
Ooids well sorted but sorting is bi-modal & micrite is enclosing these grains |
| Rounding |
Ooids are rounded |
| Micritization & envelopes |
None |
| Cement & diagenetic fabric |
Grains are cemented as they are washed onto supratidal crust |
| Porosity |
Approximately 45% intra-particle & some inter-particle leaching |
| Depositional Setting |
Supratidal tidal crust on leeside of oolite shoal |
| Diagenetic history |
Cemented by upwelling capillary waters |
Cemented crusts from the supratidal area west of Joulters Cay, a small island accreting in the northeast corner of the western arm of the Great Bahamas Bank
