processes in limestone areas - Summerhome Umasari

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.
