The chemical composition can also vary greatly from region to region as well as between different deposits in the same region. Limestone can be classified according to their chemical composition, texture and geological formation. Typically, limestone contains more than 90 % CaCO3 (calcium carbonate) and a few % MgCO3 (magnesium carbonate).
