Accordingly, CaMg(CO 3) 2 has a comparable volume to an aragonite/magnesite assemblage at pressures within the dolomite-II stability field. CaMg(CO 3) 2 is expected to have a larger entropy than the two-phase assemblage: any high temperature cation disorder, as occurs at lower pressures within dolomite, should further increase the entropy [Luth ...

All these formations contain major amounts of dolomitic marble. 4. Section 33, T39N, R28W: "exquisitely
Dolomite is a sedimentary rock made mostly from the mineral dolomite and it's also known as dolostone. Sometimes, showrooms will label Dolomite as "hard marble," and the reason for this is because it is denser than marble. Dolomite is porous, though not as susceptible to staining, etching and cracking as marble.

For chemical formulas, calcite is CaCO3 while dolomite is CaMg(CO3)2. Calcite can be commonly red while dolomite can be commonly brown, pink, tan or yellow. Calcite's hardness is lower than dolomite - calcite is 3 and dolomite ranges from 3.5 to 4 on the Moh's scale. Calcite can be scratched by copper pennies (3.5) while dolomite can not be.
