Carbonate Geochemistry
Abstract Calcite (CaCO 3 ) is one of the most common minerals at or near the surface of the earth and thus is one of the main contributors to carbonate geochemistry. Less common carbonate minerals include dolomite [MgCa (CO 3 ) 2 ]; aragonite, a calcite polymorph (mineral of the same composition as...
