Carbonate rocks are sedimentary rocks primarily composed of carbonate minerals, mainly calcite and dolomite. They form from the accumulation of biological debris, such as shells and coral, or through chemical precipitation in water. Common types of carbonate rocks include limestone and dolostone, which are often found in marine environments. These rocks play a significant role in the Earth's carbon cycle and can serve as important reservoirs for oil and natural gas. Additionally, carbonate rocks are used in various industries, including construction and agriculture, due to their abundance and unique properties.
