Boundstone

Description: Coral boundstone with dolomite cement infilling intraparticle pores.

Description: Coral boundstone with abundant encrustation features (micritisation, borings, serpulids, calcareous sponges, cyanobacteria, benthic forams, thrombolite). The groundmass consists of automicrite (clotted and lessere thrombolitic fabric) and bioclastic peloidal packstone to grainstone. Intraparticle and intergranular pores as well as intra-reef cavities are filled by, first blocky calcite and second by Fe-rich calcite cement. (Jurassic, SW Morocco)

Description: Tabulata boundstone with Fe-calcite cementation and poikilotopic and sutured mosaic dolomite cement.
