Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris. Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched.
The minerals calcite and dolomite are chemically similar and actually form a series ranging from pure calcium carbonate calcite to pure calcium, magnesium, carbonate dolomite. The magnesium atoms that substitute for the calcium are a bit smaller than those of calcium, and this affects the appearance of many dolomite crystals.
