Schematic drawings of (a) {} and (b) {} surfaces in unrelaxed state for calcite having Ca (red), O (blue), and C (green) atoms with decreasing size. Note Ca and C (representing CO3 2−) atoms with point charges account for the cation–anion mixed surfaces in both (a) and (b), and a face-centered rhombohedron pseudocell including oxygen atoms is outlined by dotted lines in (b)
