Dolomite Mineral | Uses and Properties

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

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.
