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 initiation of a thaw lake begins with the degradation of ice-rich permafrost. The natural inception of thermokarst lakes can be demarcated into two separate processes; whether in continuous or discontinuous permafrost.
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 ...
Livanjsko polje (lit. ' Field of Livno '), located in Bosnia and Herzegovina, is the largest polje (karstic field) in the world and a RAMSAR wetland site.A typical example of karst polje encircled by tall peaks and mountain ranges, the field is characterized by many unique natural phenomenons and karstic features.
Borenore's karst is surrounded by igneous rock that flowed from volcanic eruptions at nearby Mount Canobolas. [ 1 ] The 136-hectare (340-acre) reserve is situated 17 kilometres (11 mi) west of Orange , and is registered as a natural heritage site on the Register of the National Estate for its large diversity of karst morphological and ...
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 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 ...
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]
