  • Limestone: Rock Uses, Formation, Composition, Pictures

    FormationGeologyCompositionPropertiesNamesUsesAdvantagesOther usesAvailabilityLimestone is a sedimentary rock composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. It most commonly forms in clear, warm, shallow marine waters. It is usually an organic sedimentary rock that forms from the accumulation of shell, coral, algal, and fecal debris. It can also be a chemical sedimentary rock formed by the precipitation of calcium carbonate from lake or ocean water. Most limestones form in shallow, calm, warm marine waters. That type of environment is where organis
