Crystalline limestone fills in the spaces between the other ingredients. Fine-grained limestone, these smooth-looking stones don’t have visible fragments. Typically, these are formed in deeper parts of the sea where ... Rocks formed dominantly from this material are the biochemical version of limestone. Since the principal compound making up limestone is CaCO3, geologists refer to limestone as a type of carbonate rock. Limestone comes in a variety of textures, because the material that forms it accumulates in a variety of ways.Instead of being formed by acidic water slowly eating away at the rock, erosional caves are carved out by a flowing stream of water. The water carries small rocks and sand. These are capable of eroding much harder rock than limestone. Erosional caves can be formed in even the hardest of rock, such as granite.
