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 ]
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 ...
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 ...
The Floridian peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform. The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands. Flora and fauna began appearing during the Miocene. No land animals were present in Florida ...
The Pennyroyal Plateau or Pennyroyal Region, often spelled Pennyrile, [1] is a large physiographic region of Kentucky that features rolling hills, caves, and karst topography in general. It is named for Hedeoma pulegioides (the American pennyroyal), a wild mint that grows in the area.
The physiographic regions of the contiguous United States comprise 8 divisions, 25 provinces, and 85 sections. [1] The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. [2] [3] The map was updated and republished by the Association of American Geographers in 1928. [4]
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 cliffs of Duino and the gulf of Sistiana, Province of Trieste, Italy, seen from the Rilke Trail. The Karst Plateau or the Karst region (Slovene: Kras, Italian: Carso), also locally called Karst, is a karst plateau region extending across the border of southwestern Slovenia and northeastern Italy.
