Outstanding feature | Dolomitized micritic fabric replaces pelloids and intraclasts. Some circular dasyclad algal plates. |
Folk Classification | Dolomitized Pelsparite or Intrasparite |
Dunham Classification | Dolomitized Pelgrainstone or Intraclastic Grainstone |
Common Grains | Pelloids and/or intraclastst cemented by dolomite spar |
Sorting | Biomodal but well sorted |
Rounding | Rounded |
Micritization & envelopes | Grains are peloids or intraclasts with micrite envelopes |
Cement & diagenetic fabric | Complete replacement of pelloids and intraclasts by dolomite |
Porosity | 5-10% Interparticle |
Depositional Setting | Moderate energy shoal |
Diagenetic history | Complete dolomitization of pelloids &/or intraclasts & cement |
Striking replacement of either pelloids or intraclasts and micrite envelopes by micrite sized authogenic dolomite.There are the remains of what appears to be Dasyclad algal plates. Note sparse interparticle porosity.
