Formula:
CaM2+(CO3)2
Name:
After the principal species in the group.
Members of this group have a crystal structure similar to that of calcite. In dolomite, alternate Ca positions are occupied by Mg, these becoming structurally non-equivalent and the crystal point symmetry being lowered from 32/m to 3.
