Dolomite: A sedimentary rock known as dolostone or

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Dolomite: 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.

University of Minnesota’s Mineral Pages: Dolomite

Many sedimentary dolomites occur from alteration of calcite and aragonite relatively soon after their own formation, resulting in regionally extensive masses of bedded dolostone. Other secondary sedimentary dolomites form from alteration of calcite and aragonite long after these minerals had originally formed.
