Geology: Physical Characteristics Of Limestone

Feb 04, 2011 · Limestone is a sedimentary rock. Limestone is a sedimentary rock found near the surface of the Earth's crust. It tends to acidify and erode when in contact with water containing dissolved carbon dioxide or a weak carbonic acid. The main constituent of limestone is calcium carbonate. Limestone exhibits several unique physical properties.

Calcium carbonate - Wikipedia

Calcium carbonate is a chemical compound with the formula Ca CO 3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs.

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.
