What is Dolomite? 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 …

Dolomite is a common mineral. It is also known as CaMg (CO 3) 2 and is a type of compact limestone consisting of a calcium magnesium carbonate. In combination with calcite and aragonite, dolomite makes up approximately 2% of the earth's crust. The mineral was first described by and then named after the French mineralogist and geologist Deodat ...

Dolomite. Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg(CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca.
