Dolomite is a calcium magnesium carbonate with the chemical composition CaMg(CO 3) 2, constituting a rock-forming mineral found in abundance around the world.It has numerous commercial uses. Dolomite mineral is rarely found in modern sedimentary environments; however, dolomite rocks (dolostones) are common in geological history.

Dolomite is calcium magnesium carbonate, which can form outstanding crystals with wide variety of colors, often associated with other minerals. Less aesthetic dolomite rocks can build a whole mountain ranges. Dolomite (or dolostone) is also used to refer to the sedimentary carbonate rock of the same composition.
