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 valley is notable for its karst formations, which have been designated a National Natural Landmark. Grassy Cove is also home to a small unincorporated community . Grassy Cove is located atop the Cumberland Plateau , approximately 5 miles (8.0 km) east of Crossville and 5 miles (8.0 km) west of the plateau's Walden Ridge escarpment.
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 ...
Groundwater flowing through joints in these rocks creates caves and sinkholes, forming a region of karst topography. The sinkhole that contains the fossil-rich deposits of the Gray Fossil Site is the result of a series of overlapping collapse events that ultimately formed one large basin.
The geology of Tennessee is as diverse as its landscapes. Politically, Tennessee is broken up into three Grand Divisions : East , Middle , and West Tennessee . [ 1 ] Physically, Tennessee is also separated into three main types of landforms: river valley plain, highlands and basins, and mountains.
The Indiana Karst Conservancy is working to raise more awareness of the state’s unique karst landscapes. Trash and other materials get dumped into sinkholes and pits, leading to pollution ...
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.
A rare wetland type in this region is the calcareous seepage fen. These are found sparingly in the Highland Rim, and are dominated by grass of Parnassus (Parnassia grandifolia) and contain the federally-endangered Tennessee yellow-eyed grass (Xyris tennesseensis). [13] Calcareous seeps are also found near glades in the Inner Nashville Basin.
