Limestone is a sedimentary rock composed primarily of the minerals calcite and aragonite, which are crystalline forms of calcium carbonate (CaCO₃). It accounts for approximately 10% of the total volume of all sedimentary rocks, making it one of the most abundant sedimentary materials on Earth. Due to its solubility and geological characteristics, limestone bedrock commonly hosts extensive cave systems formed through natural dissolution processes over time. Its physical and chemical properties make limestone an important raw material for a wide range of construction, industrial, and environmental applications.
