Karst Wikipedia

25/02/2002· Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in

Scientists Solve Mystery of How World’s ‘Stone Forests’

This process is responsible for the famous underground limestone caves — as the rainwater percolates through the soil, it begins to break up the limestone enough to form large openings. These limestone caves can function as carbonate aquifers, producing and containing freshwater for hundreds of millions of people.

Karst terrain is formed by dissolution of soluble bedrock like limestone, dolostone, marble, gypsum, and halite. In karst, spaces or conduits form in the subsurface that allow for rapid movement of groundwater. Water moves quickly from the earth’s surface underground in these places. Naturally formed underground spaces that people can enter are called caves. Sinkholes, disappearing streams

karst National Geographic Society

21/01/2011· Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or dissolved from a weak point inside the rock. Karst landscapes feature caves, underground streams and sinkholes on the surface. Where erosion has worn away the land above ground, steep rocky cliffs

Planning for karst management in multiple-use forest: The

limestone soils may be problematic for maintaining forest productivity, water resources may be threatened by pollution of karst aquifers, and drought stress exacerbated by subterranean drainage pathways may affect tree growth. In order to successfully manage multiple-use forest areas containing sensitive geomorphic features such as karst, detailed mapping and inventories of the landforms and
