about carbonates mineral

2.3 Mineral Groups - Physical Geology - 2nd Edition

carbonates include minerals in which the anion is the CO 3−2 complex. The carbonate combines with +2 cations to form minerals such as calcite (CaCO 3 ), magnesite (MgCO 3 ), dolomite ( (Ca,Mg)CO 3) [1], and siderite (FeCO 3 ). The copper minerals malachite and azurite are also carbonates. In phosphate minerals, the anion is the PO 4−3 complex.

Dolomite - Complete Mineral Overview - MineralExpert

Dolomite is an anhydrous carbonate mineral composed of nominally equal parts calcium and magnesium, with the formula CaMg (CO 3) 2. Its chemical formula can be more clearly written as CaCO 3 .MgCO 3. Because of the presence of two various cations, which form regular layers inside dolomite structure, dolomite crystal symmetry is lower than calcite.
