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.
Karstosphere (karst and Ancient Greek: σφαῖρα "sphere") is a geosphere of the karst processes; part of the lithosphere. [1] This is distinctly developed on continental platforms. It represents the Earth's broken shell occupying 35% of its surface and embracing vast areas of continents , as well as a considerable part their underwater ...
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 ...

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 .
