What is tower karst in geology?

Tower karst are tall rock structures made up of soluble rock such as limestone. Tower karst forms as near-vertical joints and fractures are eroded downward by solution leaving parts of a previously coherent rock mass isolated from each other.

Which country is famous with tower karst?

The karst features and geomorphological diversity of the South China Karst are widely recognized as among the best in the world. The region can be considered the global type-site for three karst landform styles: fenglin (tower karst), fengcong (cone karst), and shilin (stone forest or pinnacle karst).

What defines a karst?

Karst is a type of landscape where the dissolving of the bedrock has created sinkholes, sinking streams, caves, springs, and other characteristic features. Karst is associated with soluble rock types such as limestone, marble, and gypsum.

Where are tower karsts found?

Tower karst occurs throughout southeast Asia. By far the most extensive and best developed tower karst is in the Guangxi province of southern China. This is the ultimate development of tower karst, in which the residual hills have very steep to overhanging slopes.

How did the Thailand karst form?

Once this rock is uplifted above sea level by geologic forces, ground water percolates through it and slowly dissolves it, creating a variety of solution features. Thus, if water is present to dissolve the limestone, karst landscapes can develop in almost any climatic region, including arctic and arid areas.

Why is it called karst?

The word ‘karst’ has its origins in pre-Indo-European languages, from kar, meaning ‘rock’. In Slovenia the word ‘kras’ (or ‘krs’), subsequently germanicized as ‘Karst’, derives from the name of a barren stony limestone area near Trieste, which is still considered the type area for limestone karst.

What is karst country?

One of the most interesting areas of Puerto Rico is the large Karst Country, south of Arecibo. This other-worldly group of rock formations were created by the process of water sinking into limestone. As time goes by, larger and larger basins are eroded, forming sinkholes.

What is karst and why is it important?

Karst is a special type of landscape that is formed by the dissolution of soluble rocks, including limestone and dolomite. Karst regions contain aquifers that are capable of providing large supplies of water. More than 25 percent of the world’s population either lives on or obtains its water from karst aquifers.

What and where is a karst?

Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or dissolved from a weak point inside the rock.

What causes tower karst?

Karst towers are surrounded by rivers, alluvial plains, or mangrove forests (Figure 9). These environments provide not only abundant water, but high levels of carbon dioxide as well because of the abundant vegetation that grows there. It is for this reason that tower karst occurs in these areas.

What causes karst landforms?

What is meant by karst topography?

[ kärst ] A landscape that is characterized by numerous caves, sinkholes, fissures, and underground streams. Karst topography usually forms in regions of plentiful rainfall where bedrock consists of carbonate-rich rock, such as limestone, gypsum, or dolomite, that is easily dissolved.
