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.
Worldwide, lava tubes, karst caves, and rock shelters are the most common varieties of cave. Karst caves typically form through dissolution of limestone by carbonic acid, but some caves, such as Lechuguilla, have instead been formed from the bottom up via sulfuric acid released from oil reservoirs.

Tower karst are tall rock structures made up of soluble rock such as limestone. Tower karst forms as near-vertical joints and fractures are eroded downward by solution, leaving parts of a previously coherent rock mass isolated from each other. [1] Tower karst is most common in tropical regions, [1] although it may form in other climates as well ...
The new species has so far only been found in one karst formation in Khammouane Province, the study said. This central province is about 260 miles southeast of the capital, Vientiane, and borders ...
