Longtan Gorge

Longtan Gorge

On the Bank of Wanshan Lake in Luoyang, in the cluster of Wanshan mountains in the west of Henan Province, a tourist attraction has recently emerged, and there is a temple of science, the Longtan Canyon Scenic Area of National Geopark. It is located in the mountains in the northwest of Xin'an County, Henan Province, on the Hunan bank of Wanshan of the Yellow River, 80 kilometers east of Luoyang City, and is a part of Luoyang Daimeishan National Geopark.

Xin'an scenic spot

Longtan gorge is a national AAAAA scenic spot, which belongs to the core scenic spot of Luoyang Daimeishan World Geopark. It is a gorge scenic spot with typical hongyanzhang Valley Group geological landscape. In the valley, guanxia faces each other, with pools and waterfalls linked with pearls. The gorge is beautiful and the valley is secluded. After 1.2 billion years of geological deposition and 2.6 million years of water flow cutting and whirling erosion, the high gorge, Weng Valley and mountain collapse and ground fissure wonders are unique in the world and rare in the world.

It enjoys the reputation of "the first gorge of ZhangGu in China", "ancient marine natural museum", "gorge masterpiece" and "Yellow River Landscape Gallery".

In 2009, Longtan gorge was officially renamed "Longtan Grand Canyon".

Longtan gorge is a V-shaped gorge formed by purplish red quartz sandstone cut down by flowing water, with a total length of 12 km. In the gorge, the peaks and passes are distributed in beaded shape, with steaming clouds, torrent splashing, red walls with green shade, cliffs and cliffs. The water cutting and whirling erosion in different periods have very clear abrasion marks, and the ripple mark cliff formed by giant collapse rock blocks is rare at home and abroad.

Six mysteries of nature

Water flows to high places, Buddha light Luohan cliff, giant fingerprints, heavenly book on stone, butterfly spring, immortal footprints.

On September 28, 2007, it passed the acceptance of AAAA scenic spot of National Tourism Administration.

In 2009, the company actively applied for 5A scenic spots.

In 2012, it won the national 5A scenic spot.

Main attractions

Luoyang Daimeishan National Geopark is divided into five scenic spots: Longtan gorge, Jingzi mountain, Daimei mountain, Qingyao mountain and Wanshan lake, with a total area of 328 square kilometers. It is a comprehensive Geopark which is mainly composed of sedimentary structure relics and geological landscape, and is suitable for geological disaster relics, typical minerals, water bodies and vegetation. The red rock peaks and valleys in the park, which are rare in China, set off each other with Wanshan lake of the Yellow River. The red stone rhyme, the soul of the Yellow River and the scenery of the mountains and waters are reflected in each other, forming a cluster of bright pearls with special scientific significance and aesthetic value on the Wanli Yellow River

.

Longtan gorge is a typical example of Daimeishan gorge group Geopark.

wonder

The age of the earth is about 4.6 billion years. About 1.2 billion years ago in the Mesoproterozoic, North China is an ancient ocean. Due to the action of crustal movement, the seabed sediments were lifted out of the bare ground, and more than 820 meters of purple red quartz sandstone was formed on the South Bank of the Yellow River in the north of Xin'an, which constituted the main part of the mountains in this area.

Later, under the background of neotectonic movement of the crust (from about 2.4 million years ago until now), the purple red quartz sandstone, which was originally exposed on the surface, underwent uplifting and descending, collapse, long-term water surfing and whirling, wind denudation and rain erosion, and finally formed the hongyanzhanggu group here, showing the geomorphic characteristics of Gaoxia changgu and shanzhangyandong.

This geomorphic feature not only reflects the geological evolution history of this area, but also provides strong evidence for studying the evolution of the Yellow River. There are hundreds of ancient submarine sedimentary structure relics, which become a natural museum reflecting the characteristics of ancient marine sediments in North China. The main types of ancient submarine sedimentary relics in Longtan gorge are: Gaoxia wenggu, cave niche, corrugated schist, Tianshu stone, pictograph stone, etc.

Gaoxia Lishui

Most of the existing quartz sandstone canyons in China have steep cliff wall on one side and gentle slope shape on the other. However, Longtan Canyon is characterized by continuous high gorge and double wall confrontation, which is unique in China and occupies an irreplaceable important position. It has the characteristics of rarity, typicality and particularity in science. There is a thin vein of water in the gorge, connected by pools and waterfalls, winding and zigzagging, reflecting each other with the unique high gorge and long valley, forming a beautiful high gorge water system map, which has high ornamental value, research value and popular science value.

The first landscape of Longtan Canyon is composed of red cliff, Wulong waterfall and Wulongtan. Wulong waterfall falls down from the mouth of the hanging ditch of Chibi Danya, which is more than 100 meters high. It sounds like the roaring of dragons and tigers, shaking the valley. Below is Wulong lake, which is artificially blocked. Its surface is 300 meters long and its width is 50-150 meters. The water in the Lake is blue, and you can go boating.

Walking into the gorge and passing through huanglongyu, where the grass is abundant and the forest is dense, you can enter the most representative landscape bright spot of the whole gorge - the successive dangerous gorge groups of Xiongguan. The most typical are Qinglong gorge, Heilong gorge and Feilong gorge, which are all vertical joints of Mesoproterozoic quartz sandstone developed under the background of neotectonic movement. Through the strong downward cutting of flowing water along the joint intensive parts, the two sides of cliffs stand upright and face each other. Qinglong gorge is 60 meters in length, 30 meters in height and less than 5 meters in width. The stone walls on both sides are steep, and the crabapple on the cliff wall is full of four seasons, reflecting the water. Green overflows the water surface. At noon, due to the refraction of sunlight, there seems to be a green dragon swimming on the cliff wall, so it is named "Qinglong"; Heilong gorge is 20 meters in length, over 50 meters in height and only 1-3 meters in width, The Feilong gorge is named "black dragon" because it has only one line of light in the open air and dark water in the deep valley. The Feilong gorge is winding for hundreds of meters, with uneven cliff walls and wide and narrow canyons

Dragon, so it has this name.

Corresponding to each section of the canyon are a series of water landscapes, such as Qinglong lake, Qinglong waterfall, Heilong lake, Heilong waterfall, Feilong lake, Feilong waterfall, Yinyang lake, Zhuzhu lake and Yixian waterfall. The depth of the pool is about five or six meters, and the height of the waterfall is more than ten meters. There is a gorge in front of the pool, and there is a waterfall behind the pool. Facing each other from the gorge, the pool is linked with the Pearl River, and the waterfall cascades. It's so daunting that it can be said that the scenery is so confusing that the tourists are standing there, and the steps are so dangerous that people are scared. The black dragon gorge, in particular, has a narrow valley, which looks like a crevice. The waterfall falls from a 15 meter high cliff, splashing with silver and making a sound. In the high gorge, there is light in the dark, sound in the quiet, light out, and endless fantasy. When you are in it, you feel like you are in a dream, and you feel like you are out of the world.

Wenggu cave niche

There are many natural caves in Longtan gorge. Some of them are formed by the collapse of quartz sandstone, such as the Wulong cave on the west side of the entrance of Longtan gorge and the headless Yuanshen cave in Bailong Bay. Some of them are natural caves, such as Huifeng cave at the foot of the right head cliff of qinghechuan, outside the mouth of Longtan gorge, formed by water (rain) dissolving along the cracks of dolomitic limestone in the process of natural weathering evolution. The cave body contains argillaceous dolomitic gray layer, with relatively developed fissures. The width of the cave body is different, and the depth of the cave is unpredictable. There is wind flowing at the entrance. In midsummer, it is dense and cool, while in the middle of winter, it is warm and warm, which seems to be full of spring. No matter what the weather is, it is always cool and pleasant, inviting people to stop and flow, so it is called Huifeng cave.

At the bottom of the red cliff on both sides of Longtan gorge, there are many hemispherical niches with inner arc surface, which is a geological phenomenon formed by the erosion and whirling of ancient marine sedimentary quartz sandstone. In Feilong gorge, this kind of hemispherical niche is raised from the bottom of the cliff to the middle of the cliff wall, making the whole section of the canyon appear curved face to face, small mouth and big belly. If you look up and place yourself in the urn, this is the geological wonder - the urn Valley. The hemispherical niches in wenggu were uplifted to the middle of the cliff wall during the crustal movement. This phenomenon has important scientific significance in studying the characteristics of the neotectonic movement and the crustal uplift speed in this area. There are two wenggu in Feilong gorge: the first one is the most typical, with a diameter of 20 meters and a radian of 270 degrees; the second one is cut by running water and finally connected into ZhangGu.

Ripple stone

In the 4 km long Hongshi gorge of Longtan gorge, a large number of collapse schists are distributed. These tablets vary in size. The larger ones are tens of square meters, while the smaller ones are only tens of centimeters square. Hundreds of different types of ripples can be seen on these flat and flat schists, which is a rare natural ripple Museum in China. These ripples on the stone surface are formed by physical variation of primary geological sediments under the action of water or wind in the process of earth evolution. Their forms include bedding structure, ripple structure, tent structure, spherical structure, etc
