Although the lattice of calcite is mainly composed of CaCO 3, Fe (II) and/or Mg (II) could be embedded into calcite crystal. The embedded Fe and/or Mg content can account for up to 20% in terms of mole fraction. Therefore, the actual formula for field calcite scale can be described as Ca 0.8–1.0 (Fe,Mg) 0.0–0.2 CO 3.
