  • Dolomitization mineralogy Britannica

    Dolomitization, process by which limestone is altered into dolomite; when limestone comes into contact with magnesium-rich water, the mineral dolomite, calcium and magnesium carbonate, CaMg(CO 3) 2, replaces the calcite (calcium carbonate, CaCO 3) in the rock, volume for volume.Dolomitization involves recrystallization on a large scale. The dolomite mineral grains often show distinct faces ...
