Karst 2


Karst 2 :

A type of topography in which there are numerous sinkholes and large voids, such as caves. Karst is caused when soluble rocks dissolve. Karst may form when rainwater, reacting with carbon dioxide from the air and forming carbonic acid, seeps through the soil into the rock. Soluble rock includes limestone and evaporite rocks, such as halite (salt) and gypsum. If substantial and abundant karst features were present at the Waste Isolation Pilot Project, this could increase the speed at which releases of radionuclides travel away from the repository through the subsurface
