Global distribution of major outcrops of carbonate rocks (mainly limestone, except evaporites). The English word karst was borrowed from German Karst in the late 19th century, [6] which entered German usage much earlier, [7] to describe a number of geological, geomorphological, and hydrological features found within the range of the Dinaric Alps, stretching from the northeastern corner of ...
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 ...
Karst springs - springs that often carry cave water. [29] Karst windows - small section of a underground river that is exposed to the surface. [30] Limestone - Calcium carbonate based sedimentary rock that often forms caves. [31] Losing streams - a common feature of karst areas. [32] Sinkholes - collapse features that often form cave entrances ...
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 ...
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]
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 ]
A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. [1] The term is mainly used in the UK and Ireland, where many of these landforms have developed distinctive surface patterning resembling paving blocks. [ 2 ]
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 .
