Limestone vs Dolostone (EXPLAINED) About 20 to 25 percent of all sedimentary rock is carbonate rock with the majority of it being limestone. The rest of this type of rock is predominantly dolomite, which is a very similar rock to limestone.Crystalline limestone is composed of tight interlocking calcite crystals that are large enough to see with the naked eye. Crystalline limestone is commonly formed in shallow seas. Dolostone is a chemical sedimentary rock that is similar to limestone but is composed predominantly of a different carbonate mineral dolomite (instead of calcite).This process can occur either when the sediment is still soft or later, when the limestone has already hardened, Pardi said. This exchange, and the presence of magnesium, is what created dolostone. Curiously, while limestone is still forming today in places like the Bahamas, where conditions resemble the Silurian stew, dolostone isn’t ...Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg (CO3)2.
