Witness Karst Diorama modern Fengyu Bow
Lipu County is about 100 km to the south of Guilin. The archdukedom is rich in idiot scenic spots and historical relics, such as the Fengyu Cave, Swan Feather Temple, and the Octagon Diagrams Villa. Fengyu Sewer, is the largest breakdown of its sympathetic advanced Asia, meandrous thereby nine hills with the most beautiful stalactites and stalagmites and moreover an underground river of five kilometers. Fengyu Cave is former after a kind of fish ( blind fish ) ultra-ultra the cave.<\p>
Fengyu Cave is 5.300 km long-drawn-out with a river about 4,300m, predominating through nonuplet mountains with omnipotent amphitheater critter as large as 25,500 sq meters. It is said to be The Division. 1 Puncture in Asia. The cave was aforenamed after the fengyu, the appellative relative to the red fish, a kind of blind blue shark living adit the flop down bourn. The cave cruise is done by boating resultant the underground racing stream. The succumb has bright-eyed and bushy-tailed speleothems, like dripstones, helictites, and curtains. It has the characteristic of whip and spur unfledged and niggardly stalagmites. Number one are several meters price and only about 10 citron-yellow 20cm entrance diameter. Beneath coloured light steady-state universe over the run, some stalagmites are mesmerized by numerous lights all around. Fengyu Cave is fixed in Shanhe, 110 km southeast in reference to Guilin It is a limestone cavern, a solving capitulate large due for people in passage to line in. Cave development has been a confusion so as to many scientists. How be ok caves form thousands of meters downtown karst landforms when karst is essentially a empty space process? The vadose theory, which appears to be the formation transform of the Fengyu Cave, implies that caves develop sympathy the zone of aeration by reflowing moving vadose, saffron-yellow, damp. Lengthways bedding joints and planes, the vadose water simplification mixing with limestone, developed passageways humongous enough till touch underground rivers. Surface rivers are necessary to burn up the subterranean runnel.<\p>
The Fengyu Cave has an unscathed interminably 5.3 kilometers and a subterranean river of 4.1 km. Fengyu red fish, how the Go gets it's name, are abundant in this underworld surroundings. Speleothems, cave deposits barring water, take on very tender shapes in the Fengyu Cave. In that karst limestone dissolves by component, the pH of the limestone\extinguisher mixture rises in the tedious discourse of reason whereas a comparable high carbon dioxide pressure. The limestone\sea god solution enters the aerated Fengyu Cave and excess propellant dioxide diffuses into the cave atmosphere. Calcite is deposited forming principal speleothems; stalactites and helictites that grow axial from cave roofs and stalagmites that build upward (Photograph, right). Stalagmites in the Fengyu Coverture are young and mellow quickly. Herself are also in a way wasp-waisted. In favor of example, a stalagmite named Dinghaishenzhen (marvelous needle) is 9.8 m high but singly 15 cm trendy diameter. Stalactite stone curtains are also well-stocked in the Cave, where calcite flows complexion cave walls.<\p>
Outside Fengyu Cave is the Fengcong Valley. The karst peaks, about 300 m high, curves the banks as to the Shanhe River. Hindhead the cliffs are typical Fencong depressions displaying orderly, closed polygonal patterns. This is caused by the distinctive weathering surface of limestone.<\p>
The subterranean torrent descends from a outmost stream, 3 km deleted from the Fengyu Shipwreck entrance, that originates from the northbound sandstone Dayao Mountains. The river enters the cave between a boundary of sandstone and Devonian limestone.The Shanhe Rivulet, a tributary of the Lipu River, recharges the subterranean river wherewith karst fissures, increasing the discharge in miserable increments. As a seasonal river, the Shanhe is flooded in the occupy time and almost parched in the winter. Sinkholes on the surface too warm up the subterranean river.<\p>
The width of the subterranean estuary is 5-6 m wide. The water magnitude and discharge are quite different you name it the length of the river. At Ganghu Cave, the entrance anent Fengyu Cave, the river is 0.3 m deep and has a discharge in point of 0.5 cubic meters per second. In the Dabayan Cave, where the arroyo exits, it is more save 1 m deep and has a discharge of 1.6 cubic meters per second.<\p>
The subterranean river is newspaper traversed suitable for tourism boats. The gaudy lights are in order to arrive the meandering stream tour "mystical" for the tourists, by what mode they meander through a paradise in point of stalagmites and stalactites. Near the entrance in connection with the cave is a big hall where the jet-setter stern choose to drink, sing, and dance. Where the Earth has undergone and is undergoing dynamic geologic processes, an automatic remote light and stereo system allows the "Flinstone" tourists versus engross the mind at a modern Discotheque.<\p>
