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 ...
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 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 ]
Karst is a landscape filled with limestone or other similarly soluble rocks underground. Acidic waters erode the underlying rocks over millions of years and leave an underground drainage system ...
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.

Fengcong karst dominates the course of the Li River and is defined as a group of limestone hills with a common limestone base, with deep depressions (or dolines) between the peaks, and sometimes described as peak cluster depression karst. Hundreds of caves are present in this terrain, with 23 having passages longer than -1 km alongside the Li ...
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 .
