Dolomitic limestones come from natural deposits which contain both calcium and magnesium carbonates. The magnesium content of limestone is especially important where soils are deficient in this essential plant nutrient.Calcitic limestone. calcium carbonate. CaCO 3. More reactive than dolomitic limestone. Adjust pH more quickly and may raise the substrate pH higher than the same amount of dolomitic limestone. Dolomitic limestone. calcium magnesium carbonate. CaMg (CO 3) 2. Less reactive than calcitic limestone.Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
