Grainstone
|
Phosphatic granular coarse-grained grainstone with well-rounded micrite clasts, phosphate clasts, and partially to completely quartz-replaced carbonate grains. Quartz is euhedral to subhedral where replacing micrite. Cement is mixture of quartz, phosphate, and dolomite. Very interesting petrogenesis. See also W77-226. |
