Dolomite can be a double carbonate, With all the formulation CaMg(CO3)2. Secondary dolomitization of limestone is widespread, wherein calcite or read aragonite are converted to dolomite; this reaction boosts pore Room (the unit mobile quantity of dolomite is 88% that of calcite), which could make a reservoir for oil and gasoline. These two mineral species are users of eponymous mineral teams: the calcite team incorporates carbonates with the general system XCO3, and also the dolomite team constitutes minerals with the general formula XY(CO3)2.[144]
