Typical karst terrain of the Dinaric Alps Lijiang fengcong in Guilin as part of the South China Karst Karst formation of the Serra de Tramuntana. Karst (/ k ɑːr s t /) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite.
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
UNESCO describes the South China Karst as "unrivalled in terms of the diversity of its karst features and landscapes". [1] The huge karst area of South China is about 550,000 km 2 in extent. The karst terrain displays a geomorphic transition as the terrain gradually descends about 2000 meters over 700 kilometers from the western Yunnan-Guizhou ...
China's karst regions are almost all formed in rocks of Devonian to Triassic age. [11] [12] Near Guilin the lowering of the base level, through uplift and river erosion, has formed prominent karst hills. It is estimated that the river erodes down 50–100 mm/kyr, from this the age of the karst landscape is estimated at 10–20 million years .
Glaciokarst is a geological term that refers to a specific type of karst landscape that has been influenced significantly by past glacial activity. [1] Karst landscapes consist of distinctive surface and subsurface landforms. These landforms are a result of the dissolution of soluble rocks like limestone, gypsum or dolomite by water. [2]
It is a morphological form frequently found in the outer Dinaric Alps anywhere between Slovenia and Greece, but large closed karst depressions are found on all continents in different landscapes and therefore uvala has become a globally established term.
The Indiana Karst Conservancy is working to raise more awareness of the state’s unique karst landscapes. Trash and other materials get dumped into sinkholes and pits, leading to pollution ...
Karst lakes are found in the area around the Harz Mountains of Germany (e. g. the Juessee and the Bauerngraben in the South Harz Karst Landscape Biosphere Reserve, an episodic karst lake on the Karst Trail), [1] in South Germany (e.g. the Eichener See), in France in the region of Quercy, in Estonia the Tudre and the region of Salajõe, [2] in Slovenia (e. g. the Cerkniško jezero), in ...
