Outstanding feature |
Grapestones and pelloids in micrite matrex |
Folk Classification |
Intramicrite |
Dunham Classification |
Grapestone Wackestone |
Common Grains |
Grapestones and pelloids with micrite matrez |
Sorting |
Poorly sorted |
Rounding |
Local rounding of grains |
Micritization & envelopes |
Mcritization of grapestones and pelloids |
Cement & diagenetic fabric |
Micrite cementing and replacing grains |
Porosity |
1% in fractures and leached voids |
Depositional Setting |
Low energy bank crest or lagoon |
Diagenetic history |
Micrite compaction and then later cementation |
Striking replacement of grains by micrite. Low energy sink for potentially higher energy grains. looks like a lagoon setting to me!!
