Limestone pavement

A limestone pavement is a horizontal surface of exposed limestone showing the effects of weathering. Since weathering action is always more pronounced along cracks and crevices it appears to break up the surface into segments which, if they are roughly rectangular, can give the appearance of an artificial pavement. More usually though resulting blocks are less regular. In Geographical studies the weathered fissures are sometimes called "grikes" or "grykes" while the resulting blocks are known as "clints" derived from North of England dialect.
