  • How do you recognize limestone and marble? [USGS]

    How do you recognize limestone and marble? The main difference between limestone and marble is that limestone is a sedimentary rock, typically composed of calcium carbonate fossils, and marble is a metamorphic rock. Limestone forms when shells, sand, and mud are deposited at the bottom of oceans and lakes and over time solidify into rock.

    Marble, on the other hand, is a rock formed when limestone recrystallizes into marble during the mountain-building process. When rocks are formed, limestone is heated and squeezed which causes the grains to recrystallize. It is metamorphic and is usually used as building material and in sculptures.
