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 Mississippi River as well as the Tennessee and Cumberland Rivers formed and cut deep into the valleys. The Nashville Basin , which in reality is a geologic dome , was pushed up from underneath by a mantle plume , exposing softer strata that with additional erosion on the Highland Rim surrounding the basin expanded the size of the basin.
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 ...
Emergent shrub sloughs are found along the bottoms of major rivers, such as the Cumberland River and Tennessee River. These are dominated by buttonbush (Cephalanthus occidentalis), and along the Tennessee River contain bald-cypress (Taxodium distichum). These sloughs were historically widespread, but dam construction and agricultural activity ...
Karst springs - springs that often carry cave water. [29] Karst windows - small section of a underground river that is exposed to the surface. [30] Limestone - Calcium carbonate based sedimentary rock that often forms caves. [31] Losing streams - a common feature of karst areas. [32] Sinkholes - collapse features that often form cave entrances ...
A Laodracon carsticola, or Khammouan karst dragon, perched on a rock. The new species has so far only been found in one karst formation in Khammouane Province, the study said.
