Dolomite Mineral – Rawedge

The mineral dolomite is commonly found in deposits of a sedimentary rock called dolostone. There are two types of materials often called dolomite, a true chemically uniform calcium magnesium carbonate with the chemical formula CaMg(CO3)2, and a dolomitic limestone, which is just an irregular mixture of calcium and magnesium carbonates.
