Calcite is the most stable polymorph of CaCO 3 on the Earth's surface: the others are aragonite (stable at high pressure, metastable at ambient conditions) and the very rare and unstable vaterite. Calcite has a first-order structure that is similar to table salt (halite; NaCl), which has a regular, cubic arrangement of Na + and Cl – ions.
