   Limestone
   A rock composed mainly of calcium carbonate CaCO3. Limestones comprise a large variety of rocks including carbonate muds and oozes, chalks, ooliths and bioclastic limestone. They form in a variety of environments from deep sea (but above the carbonate compensation depth), temperate seas, tropical sea, lakes and rivers. Most caves are found in limestones due to erosion by acidic water. Limestones erode into karst topography.

   Limestone
   A sedimentary rock made of calcium carbonate. In the Knockan Crag area this type of rock is known as Durness limestone after the village on the north coast. It tells us that this part of Scotland was once near the equator since limestone can only form in warm shallow water: there needs to be a certain temperature and lots of light for the chemical ...

    Limestone
    Sedimentary rock composed of carbonate minerals, especially calcium carbonate. Limestone can be created by clastic and non-clastic processes. Clastic limestones are formed from the break up and deposition of shells, coral and other marine organisms by wave-action and ocean currents. Non-clastic limestones can be formed either as a precipit...
