  • 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
  • Limestone caves - The Australian Museum

    This slightly acidic water dissolves the rock, forming cavities which can enlarge and join up to make larger cave systems of interconnected chambers. An underground water flow can develop when many rain-fed subsurface drainages join up, or a river can be captured by an open cavity collapse structure (sink hole or doline) and flow underground.
