· Limestone is a sedimentary rock. It’s made up of calcium carbonate. It forms from the shells and bone fragments of organisms, meaning it has lots of fossils. It’s a great building material and is used for flooring, walls, and decoration. Limestone often has fossils that give us a glimpse into the past.

· Mineralogical limestone is composed of calcite (CaO = 56% + CO 2 = 44%) and in recent deposits also called aragonite. Limestone, when pure, contains 90–99% of CaCO 3 and is classified as high calcium limestone. When magnesia or MgO percentage is 18% or more, it is categorized as magnesian limestone.
