About Calcite GroupHide

Formula:
ACO3
A = Ca, Mg, Mn#2+#, etc.
Name:
After the principal species in the group.
Calcite group structures are taken by nitrates and carbonates of relatively small cations, including Li, Na, Mg, Ca, Fe2+, Zn, Co2+, and Cd.

The structure of calcite and its related species is ionic and resembles that of NaCl, the place of the spherical Cl ions being taken by planar (CO3)2- or (NO3)1- groups. These groups are arranged in parallel position in the crystal with their threefold symmetry axes oriented along [0001]. This arrangement leads to the strong birefringence of calcite-group minerals.

Click on any node to view relationships. Formula-derived relationship network for the group members above. Use Find related species to add formula-neighbour species outside the current group view. Solid links show inferred chemical differences; dashed violet links show same-formula crystallographic differences. Hydration states are not treated as relationship changes. These relationships do not imply any real-world substitution reactions between these species.
