Karst - Wikipedia
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.

2021年7月20日 · Karst terrain is created from the dissolution of soluble rocks, principally limestone and dolomite. Karst areas are characterized by distinctive landforms (like springs, caves, sinkholes) and a unique hydrogeology that results in aquifers that are highly productive but extremely vulnerable to contamination.

2024年10月31日 · Karst topography is a unique geological formation that arises in areas where water-soluble rocks, such as limestone, dolomite, or gypsum, are predominant. This landscape is characterized by sinkholes, disappearing streams, caves, and …
12.2: Karst Landscapes, Landforms, and Surface Features
2023年11月24日 · The characteristics of karst landscapes vary depending on factors such as: soluble bedrock type, climatic environment (more specifically precipitation and temperature), geographic position (both globally and locally), overlying soil materials, and …
Karst topography: Formation, processes, characteristics, …
2024年1月1日 · Karst refers to any topography or landform that forms over soluble rocks. The classic karst landforms, which include enclosed depressions, sinking streams, and caves, are primarily generated by surface and subsurface waters dissolving rocks; mechanical erosion plays a secondary role.
12.1: Karst Landscapes and Systems - Geosciences LibreTexts
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.

2024年11月15日 · As previously noted, karst landscapes owe their existence to the removal of bedrock in solution and to the development of underground drainage without the development of surface stream valleys. Within these broad constraints, karst landscapes show much variation and are usually described in terms of a dominant landform.
