1. Longquan Gorge in the park is a typical carbonate karst valley landform, which is formed by dissolution-erosion, with a relative height difference of 200-400 meters. Karst caves appear along the upper valley of the canyon, and the source of streams in the canyon is the underground river in Meigong Karst Cave.
2. There are typical karst cave geological landscapes in the park, and cave sediments are typical and concentrated. Karst caves are layered. China's ancient "Kyushu Universal Bridge" is a four-story natural bridge, and Meihuagong Cave is a nine-story cave.
3. There are typical karst peak forests, peak clusters, skyline, Tiansheng Bridge, karst funnel and other landscapes in the park. Xianglu Mountain is densely forested with various forms. Xianrenfu three-arch natural bridge is another natural bridge formed by carbonate karst.
4. The siliceous banded limestone of the Lower Permian Maokou Formation in the park is the standard stratum of the Lower Permian in South China, and the silty carbonaceous shale and siltstone stratum at the bottom of Qixia Formation is the standard stratum of the boundary between Carboniferous and Permian.
5. The anticline and syncline of the park and its surrounding areas (Qiaotou River, Caijiabian-Tang Shuang anticline, Chetianjiang syncline, etc.). ) is a typical regional fold and a typical coal-bearing syncline in this area.
6. There are standard fossils in the park that can be divided into Carboniferous and Permian, namely, Kobayashi and Xiaofang from the Middle and Upper Carboniferous, and Shiwage from the Lower Permian.
7. A complete underground water network consisting of five major underground rivers with a total length of 35 kilometers and dozens of spring points within a range of about 40 square kilometers is typical and peculiar. 1. Karst caves are developed in the park. There are many kinds of chemical deposits in caves with unique scenery, which are rare in caves in China and even in the world. The Plum Blossom Palace Cave with nine caves, the slender goose tube group with the longest length of 2.5m, the multi-level natural bridges and karst waterfalls in the ancient Shenzhou Cave, and the lifelike murals on the rock wall and in the cave (photo 2-20) are rare in China and even in the world.
2. Xianren Bridge across Renxian River is a three-arch overpass composed of a single-arch Tiansheng Bridge and a double-arch Tiansheng Bridge. The single arch is 40m high and spans10m. This double arch bridge is 50 meters high and spans 30 meters. In addition, there are four stone peaks beside the bridge, just like piers, waiting to be repaired. Such a wonderful and spectacular overpass Tiansheng Bridge is a must in the world.
3. There are strange stones and wonderful stones in the park, with one stone and eight views and different scenery. Its lifelike form and wonderful scenery are rare; "The sky bomb is about 10 ton" and is about 5 meters high (photo 2-2 1). It stands at the top of the cliff at an angle of 60 degrees with the bedrock. The contact surface between the two stones is only 50cm2. One person can shake it down with his hands, but dozens of people try hard but don't fall down. It can be said that it is a must in the world.
4. Lotus Springs in the park are karst springs with an area of1.200m2.. Spring water gushed from five spring holes, forming five lotus flowers protruding slightly upward. The maximum flow of the spring is 5 cubic meters per second, and the diameter of running water is about 2 meters. It is a rare super-large karst spring in China. The systematicness and integrity of park geological relics are mainly reflected in the following aspects:
1. There are many types of geological relic landscapes inside and outside the park. From stratum formation to tectonic movement to modern landform, the whole formation process and development stage of geological relics are preserved in a complete system with rich and colorful contents.
2. The development types of carbonate karst landforms in the park are complete, and the formation process and development stage are complete, including gullies, stone buds, funnels and other landforms in the young age, valleys, peak forests and peaks in the middle age, solitary peaks and residual hills in the old age.
3. Saihai Karst Lake is an underground river with joints and fissures along the northwest direction, which is formed by crustal uplift and cave roof collapse. It is the main gathering place of groundwater in the area, and forms a complete underground water network with underground rivers, springs, fissure water and streams in the park.
4. Carboniferous strata and Permian strata in the park are completely distributed, which is a complete standard section of Carboniferous-Permian strata.
5. There are complete anticlines and synclines inside and outside the park, such as Chetianjiang syncline and Qiaotouhe syncline.
6. There are two complete groundwater storage structures inside and outside the park, namely Qiaotou River syncline storage structure and Chetian River syncline storage structure. Meijiang Park is rich in scenic spots, complete in landscape and beautiful in scenery. The predecessors said that Meijiang landscape has the characteristics of "strangeness, danger, vigor, uniqueness, coolness, elegance, interest and spirit", namely, "the strangeness of Xianren Bridge, the danger of Shuanglong Cave, the grandeur of Shenxian Cave field, the coolness of Yunmeng Temple, the magic color of Lion Mountain, the interest of boating in Yanmen and the god of lotus Guanyin". With the development of Meijiang Park and the discovery of many landscapes, the beauty of Meijiang landscape should be characterized by five words: strangeness, danger, strength, beauty and beauty.
Deep and winding canyons, steep cliffs, rocks with different shapes, Anaqi caves in Tibet, waterfalls hanging from cliffs, gurgling streams, towering natural bridges and lush forests constitute magnificent, steep, wild and beautiful natural scrolls, which have high aesthetic appreciation value. The karst landform of carbonate rocks in the park has unique development conditions and complete development forms. There are endless mysteries buried in caves with different landscapes; The unique miniature landform and underground water network reflect the shaping of landform landscape by karst and hydrodynamic geology; The clear structural characteristics and lithofacies of carbonate rocks provide important geological evidence for regional geological evolution. Such precious and rich geological relic resources in the park contain profound scientific connotations in topography, paleontology, stratigraphic lithology, geological structure, hydrogeology, crustal movement and so on. They are important materials for geoscience research, investigation and popular science education, and have high scientific value.
