Karst (/ k ɑːr s t /) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground.
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 ]
The region is recognized as the world’s type area for karst landform development in the humid tropics and subtropics. The World Heritage Property of South China Karst is a serial property that includes seven karst clusters in four Provinces: Shilin Karst, Libo Karst, Wulong Karst, Guilin Karst, Shibing Karst, Jinfoshan Karst, and Huanjiang Karst.
A polje, also called karst polje or karst field, [1] [2] [3] is a large flat plain found in karstic geological regions of the world, with areas usually in the range of 5–400 km 2 (2–154 sq mi). The name derives from the Slavic languages , [ 4 ] [ 5 ] where polje literally means 'field', whereas in English polje specifically refers to a ...
Karst lakes are formed as the result of a collapse of caves, especially in water-soluble rocks such as limestone, gypsum and dolomite. This process is known as karstification . They can cover areas of several hundred square kilometres.
The Karst is renowned for its strong red wine, known as teran, prosciutto and its traditional cuisine, which is a mixture of Mediterranean and Central European cuisine. The traditionally produced Karst prosciutto , a sort of dry-cured ham , is protected at the European level .
The formation of permafrost thaw lakes due to warming climate is a positive feedback loop, as methane, nitrous oxide and carbon dioxide are released as permafrost thaws, contributing to further climate warming. [1] [2] The Batagaika crater in Siberia is an example of a large thermokarst depression.
