Formation

  • Limestone Formed through layering and compounding of dead animals, plantsand calcium carbonate, under great pressure
  • This was forced above sealevel due to movement of the earth's crust
  • Limestone is a permiable and sedimentary rock, its is also alkali
  • The natural, carbonic acids in rainwater, dissolves the limestone
  • This is chemical weathering
  • Over thousands of years this creates large cracks or Grykes, which can be up to 3 meters deep
  • Iscolated Clint rocks can also be found because of glacial movement
  • Glacial Soils don't support much vegitation however, many rare wildflowers can be found eg. Gention
  • The Burren is one of the largest Karstic Limestone pavements in Europe
  • Part of it is one of Irelands 6 national parks
