  • Difference Between Limestone and Dolomite

    Dec 03, 2013Dolomite. Dolomite is also a carbonate mineral but is made of 'calcium magnesium carbonate' instead of pure calcium carbonate material. Therefore, dolomite is called a double carbonate rock, and it doesn't readily dissolve in dilute acidic media. The way dolomite is formed is not quite clear, and it has been found that it forms under high
