Calcite, CaCO3, gets its name from chalix the Greek word for lime. It is one of the most common minerals on the surface of the Earth, comprising about 4% by weight of the Earth's crust and is formed in many different geological environments. Limestone, a sedimentary rock, becomes marble from the heat and pressure of metamorphic events.
