About Dolomite GroupHide

A = Ca, Ba
M = Fe2+, Mg, Mn, Zn
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.

Chemical Properties of Dolomite GroupHide


A = Ca, Ba
M = Fe2+, Mg, Mn, Zn
