Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral foraminifera and molluscs Its major materials are the minerals calcite and aragonite which are different crystal forms of calcium carbonate CaCO 3 A closely related rock is dolomite which contains a high percentage of the mineral dolomite CaMg CO 3 2
