Dolomite and Dolomitization | SpringerLink
The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder and …

Dolomite: occurrence, evolution and economically
Dolomite, the rock, contains a large proportion of dolomite the mineral. Ideal dolomite has a crystal lattice consisting of alternating layers of Ca and Mg, separated by layers of CO 3 and is typically represented by a stoichiometric chemical composition of CaMg(CO 3 ) 2 where calcium and magnesium are present in equal proportions (Fig. 1A) .

The prevalence of massive dolomites in the ancient rock record cannot be reconciled with their striking absence from modern environments. This irregularity is compounded by the experimental difficulties in synthesizing primary dolomite (precipitation of the mineral phase directly from aqueous solution) at low–temperatures (less than 50 C).
