  • Which Acids Dissolve Limestone?

    2020-4-3 · Limestone is made up mainly of calcite that is the chemical compound calcium carbonate. Carbonic acid, which is a weak acid, forms when rainwater and carbon dioxide in the air react with one another. When carbonic acid comes into contact with limestone or calcium carbonate, it can cause it to dissolve over a long period of time.

  • Limestone pavement | The Wildlife Trusts

    2  · Limestone pavement comprises exposed, flat expanses of Carboniferous, Dalradian and Durness limestone. The flat slabs of rock are scored with deep, undulating fissures (known as ''grykes''). These can be up to 6m deep, although most are 1-2 m. Shallow erosion pans and pock marks are also found on the intervening blocks (''clints'').
