Field features. Dolomite occurs in many carbonate rocks like the homonymous dolomite (alternatively known as dolostone) and dolomite marble. Dolomite often coexists with calcite, which has nearly identical rhombohedral habit, rhombohedral cleavage, and color (colorless of white).

Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and ...

Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. Learn more about the structure, properties, and uses of dolomite in this article.

Uses. Dolomite is used as a source of magnesium metal and of magnesia (MgO), which is a constituent of refractory bricks. Dolostone is often used instead of limestone as an aggregate for both cement and bitumen mixes and also as a flux in blast furnaces. The use of dolostone as a flux has increased, especially since environmental contamination ...
