Dolostone is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2 CaMg ( CO 3) 2. Dolomite contains nearly equal amounts of magnesium and calcium. Most dolomites formed as a magnesium replacement of limestone or lime mud before lithification.

· Sedimentary carbonate rocks consist predominantly of carbonate minerals (as the name implies). There are two main types of carbonate rocks, dolomites and limestones. The first is modally dominated by dolomite (CaMg(CO 3) 2), the second by calcite (CaCO 3) and there is a complete gradation between the pure dolomite and
