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 ...
Natural conditions, including the bora (Slovene: burja) wind, and the local way of life all shaped the elements of Karst architecture, creating simple but well-defined forms. One of the main tourist centers in the area is Lipica , with its stud farm (the home of the Lipizzan horse breed) and other tourist facilities.
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 ...
“We have over 4,000 reported karst features and several thousand caves,” Selig said. “We’re still finding new caves all the time and there’s still a lot to learn about Indiana’s caves.”
Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks [1] or suffosion processes. [2] Sinkholes can vary in size from 1 to 600 m (3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms.
Underground lake within Cross Cave in Slovenia, one of 22 such lakes. An underground lake (also known as a subterranean lake) is a lake underneath the surface of the Earth. . Most naturally occurring underground lakes are found in areas of karst topography, [1] [2] where limestone or other soluble rock has been weathered away, leaving a cave where water can flow and accumu
The Caves of Aggtelek Karst and Slovak Karst are a series of over 1000 karst caves spread out over a total area of 55,800 ha (138,000 acres) along the border of Hungary and Slovakia. [1] With an exceptional diversity of karst structures and complex cave systems developing from both temperate and tropical processes, the caves and surrounding ...
