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.
Gypsum stalactites in a cave formed via sulfuric acid dissolution (Lechuguilla Cave, New Mexico) A solutional cave, solution cave, or karst cave is a cave usually formed in a soluble rock like limestone (Calcium carbonate CaCO 3). It is the most frequently occurring type of cave.
Speleogenesis is the origin and development of caves, the primary process that determines essential features of the hydrogeology of karst and guides its evolution. It often deals with the development of caves through limestone, caused by the presence of water with carbon dioxide dissolved within it, producing carbonic acid which permits the dissociation of the calcium carbonate in the limestone.
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 vocabulary includes words used in science fiction books, TV and film. A second category rises from discussion and criticism of science fiction, and a third category comes from the subculture of fandom. It describes itself as "the first historical dictionary devoted to science fiction", tracing how science fiction terms have developed over time.
Glaciokarst is a geological term that refers to a specific type of karst landscape that has been influenced significantly by past glacial activity. [1] Karst landscapes consist of distinctive surface and subsurface landforms. These landforms are a result of the dissolution of soluble rocks like limestone, gypsum or dolomite by water. [2]
The dictionary is a useful resource for both fans of science fiction and "for scholars interested in the history of science and technology", according to Elizabeth Swanstrom, co-editor of the journal Science Fiction Studies and an English scholar at the University of Utah.
However, the increasing body of literature and data collected on karst on all continents, and the global insight that climate ought to be considered as an essential genetic factor in all karst analysis, [4] raised growing concern that this definition may be unsatisfactory.
