| Micritization & envelopes |
Some alteration of the margins of bioclasts |
| Cement & diagenetic fabric |
Micrite |
| Porosity |
25% interparticle and intraparticle |
| Depositional Setting |
Low energy proteced area in reef |
| Diagenetic history |
Early disolution of some of aragonite, eg Halimdeda. |
This fabric is typical of a cemented reef fabric. The high energy grains accumulated in a very low energy setting within the reefs which was exposed to marine waters and then freshwater diagenesis.
