What Is Limestone? In order to properly understand limestone’s many locations across the globe, you have to first understand how it’s made. There are considered two methods by which limestone is created: marine creation and evaporative creation. No matter its creation process, limestone is defined by the presence of particular minerals. For example, the most common of these rocks is limestone, which is made of calcium carbonate (CaCO 3). As shown in Equation 1, when calcium carbonate is exposed to an acid (demonstrated using sulfuric acid, H 2 SO 4, which is the primary acid in acid rain), the carbonate compound (CO 3 2-) reacts to create carbon dioxide (CO 2) gas and water (H ...travertine, dense, banded rock composed of calcite (calcium carbonate, CaCO 3).Formed by the evaporation of river and spring waters, it is a variety of limestone that has a light colour and takes a good polish; it is often used for walls and interior decorations in public buildings.
