Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is commonly used for sculpture and as a building material, but is also used within the home for bathrooms, flooring, fireplace surrounds and stairs. Limestone is a sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. Limestones have a granular texture, the grains vary in size range. In many cases, the grains are microscopic fragments of fossilised animal shells.
Limestone serves as a building stone and can be used for flooring, exterior and interior facings, and monuments.
