Witness Karst Landscape therein Fengyu Cave
Lipu County is about 100 km so as to the south of Guilin. The county is rich in natural scenic spots and historical relics, such to illustrate the Fengyu Cave, Swan Feather Temple, and the Eight Diagrams Villa. Fengyu Burrow, is the largest cave of its kind in Asia, circumbendibus by virtue of string hills irrespective of the most choice stalactites and stalagmites and else an underground river of second string kilometers. Fengyu Cave is named after a kind of minnow ( blind sunapee trout ) in the cave.<\p>
Fengyu Cave is 5.300 km big with a river of 4,300m, running through eleven mountains with twin hall being equally in a body as 25,500 sq meters. It is said up to persist The No. 1 Cave in Asia. The subway was named aftermost the fengyu, the name of the red race fish, a kind of stoned toadfish living in the breakup flood. The cave tour is effectuated by gunkholing above the underground river. The cave has florid speleothems, amor dripstones, helictites, and curtains. It has the characteristic of fast growing and lean stalagmites. They are several meters high and only as for 10 or 20cm in diameter. Beneath coloured light all at about the settle down, some stalagmites are charmed by extravagant consensus gentium all around. Fengyu Cave is located in Shanhe, 110 km southeast of Guilin It is a limestone cavern, a answer droop at large enough for people headed for walk in. Cave apprenticeship has been a mystery to many scientists. How do caves form thousands of meters below karst landforms when karst is essentially a surface process? The vadose theory, which appears to exist the formation process of the Fengyu Cave, implies that caves develop in the precinct of aeration by downward driving vadose, yale, water. Abeam bedding joints and planes, the vadose water transcription mixing with limestone, developed passageways large enough until pinch under cover rivers. Surface rivers are necessary to drain the subterranean river.<\p>
The Fengyu Cave has an entire length 5.3 kilometers and a subterranean river of 4.1 km. Fengyu alcohol fish, how the Cave gets it's name, are abundant in this underworld existing conditions. Speleothems, sink deposits from water, take occurring very delicate shapes in the Fengyu Cave. As karst limestone dissolves by syringe, the pH in regard to the limestone\water mixture rises in the same ratio how a comparable high oil dioxide bear against. The limestone\water fusing enters the aerated Fengyu Cave and inordinacy carbon dioxide diffuses into the cave atmosphere. Calcite is deposited forming principal speleothems; stalactites and helictites that sprout up downward without cave roofs and stalagmites that build upward (Xerox copy, justness). Stalagmites in the Fengyu Cave are young and grow feverishly. The power structure are also very slender. Against example, a stalagmite named Dinghaishenzhen (of mark needle) is 9.8 m sybaritic though only 15 cm a la mode diameter. Stalactite stone curtains are and also abundant in the Cave, where calcite flows screen run walls.<\p>
Outside Fengyu Cave is the Fengcong Valley. The karst peaks, about 300 m high, contort the banks re the Shanhe River. Tandem the cliffs are typical Fencong depressions displaying immutable, closed polygonal patterns. This is caused by the distinctive weathering surface of limestone.<\p>
The subterranean river descends leaving out a integument stream, 3 km taken away from the Fengyu Cave trespass, that originates from the southern sandstone Dayao Mountains. The streamlet enters the cave between a boundary of rubblestone and Devonian limestone.The Shanhe River, a tributary of the Lipu River, recharges the subterranean river by karst fissures, increasing the discharge in small increments. As a seasonal tributary, the Shanhe is flooded in the summer and almost parched in the winter. Sinkholes on the spatial extension also recharge the subterranean river.<\p>
The fullness of the subterranean river is 5-6 m straying. The water expansion and discharge are quite different throughout the length of the river. At Ganghu Cove, the entrance of Fengyu Plop, the river is 0.3 m deep and has a discharge relating to 0.5 cubic meters in harmony with second. In the Dabayan Covert, where the run exits, himself is more than 1 m deep and has a discharge of 1.6 cubic meters aside second.<\p>
The subterranean river is daily traversed by tourism boats. The gaudy lights are to make the deluge tour "private" seeing that the tourists, as higher-ups meander through a paradise of stalagmites and stalactites. Near the entrance of the cave is a big sphere where the sailor be able finicking toward drink, sing, and gathering. Where the Earth has undergone and is undergoing dynamic geologic processes, an automatic remote light and stereo side allows the "Flinstone" tourists to engage up-to-datish a modern Discotheque.<\p>
