Carbonates
are broken into 2 major groups by composition and by the types of materials
in them - some have special names.
Limestone
- Is made up of Calcite and Aragonite (CaCO3)
| Coquina
- the rock consists of cemented pieces of shells and fossils. |
| Reefstone
- the main structure of the coral reef can be seen. |
| Oolitic
- consists of cemented Oolites - rounded beads of carbonate material
generally of course sand size. |
| Massive - featureless
masses of carbonate. |
