Karst (/ kɑːrst /) is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite.

2022年4月27日 · Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.

2024年12月27日 · karst, terrain usually characterized by barren, rocky ground, caves, sinkholes, underground rivers, and the absence of surface streams and lakes. It results from the excavating effects of underground water on massive soluble limestone.

2024年7月3日 · Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or . …

2023年11月24日 · Most small-scale karst features of a karst landscape (mm to cm in size) are associated with linear channels, furrows or grooves that form on soluble rock outcrops or rock faces, particularly limestone.

2021年7月20日 · Karst aquifer systems are present throughout parts of the United States and some of its territories and are developed in carbonate rocks (primarily limestone and dolomite) that span the entire geologic time frame.

2021年3月24日 · Karst topography refers to a type of subterranean limestone caverns landscape, as well the mysterious-looking formations like caves, surface sinkholes, and rocky, overhanging cliffs, as a result of a specific natural occurrence.

2023年11月24日 · Karst ecosystems or karst biota refers to all the plants and animals living in, or using, karst. This includes the flora and fauna of surface epikarst cavities, cave ecosystems, cave entrance zones or large sinkholes, as well as the broader karst landscape.

Karst provides important resources beyond drainage and drinking water. It offers habitat for unusual, rare, and endangered species in its caves, springs, and among its unusual landforms. Some of the most fantastically scenic landscapes on Earth are in karst.

“ We may define karst as comprising terrain with distinctive hydrology and landforms that arise from a combination of high rock solubility and well developed secondary (fracture) porosity. Such areas are characterized by sinking streams, caves, enclosed depressions, fluted rock outcrops, and large springs.
