Dolomite: A Mineral in Your Daily Life

Card image

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2 .

Dolomite is rarely found in modern sedimentary environments, but dolomite stones are very common in the rock record. They can be geographically extensive and hundreds of feet thick. Most rocks that are rich in dolomite were originally deposited as calcium carbonate muds that were postdepositionally altered by magnesium rich pore water to form dolomite.
