A 2000-meter ice waterfall group has formed in Yuntai Mountain, Henan Province. How did this scene come into being?

202 1 1 3 1 Yuntai Mountain, Jiaozuo World Geopark, Henan Province saw a group of ice waterfalls with different shapes, which attracted many tourists and photographers to take pictures.

Yuntai Mountain Scenic Area Yuntai Mountain Scenic Area is located in Xiuwu County, Jiaozuo City, Henan Province, with a total area of 280 square kilometers. It is a popular science eco-tourism scenic spot featuring the beautiful scenery of Taihang Mountain and the geological landscape of the canyon. Yuntai Mountain, with a drop of 365,438+04m, is one of the largest waterfalls found in China.

Yuntai Mountain Scenic Area is rich in geological relics, and rock strata 3.4 billion years ago have been discovered. In the past 3 billion years, Archean, Yuanguyu, Paleozoic and Cenozoic strata have been formed. Especially in the past 23 million years, the intense uplift of neotectonic movement and the deep undercutting of water erosion have created a canyon group with two opposite cliffs and various dynamic waterfalls, springs, streams and pools in Yuntai Mountain. Isomorphism has become? Yuntai landform? Scenery? .

On February 3, 2004, 65438 was selected as the first batch of world geoparks by UNESCO. On may 8, 2007, it was approved as a national AAAAA-level tourist attraction [5]? . 20 14 1 is listed as a natural scenery tourism project in key tourist areas of resource-based cities.

2. The origin of Yuntai Mountain Scenic Area is a Proterozoic Wang Yang. With the passage of the century and the change of the earth's crust, it gradually rises and bulges, forming a plain. During the orogeny more than one billion years ago (Ordovician and Sinian), the landform changed greatly. During the Yanshanian period, mountains rose in the north and plains fell in the south. Under the influence of Himalayan orogeny, the mountains rose sharply and rivers cut rapidly, forming a deep and steep canyon. Later, the surface and groundwater dissolved the rocks along the cracks, coupled with the influence of other weathering forces, resulting in today's rock shape? .

Yuntai Mountain Scenic Area is located in the North China Rift Zone and Xi 'an-Xi 'an of Cenozoic East Asian Rift System in North China Block. Zhengzhou? The intersection of the east-west rift transition zone near Xuzhou. Controlled by the deep fault in front of Taihang Mountain, during Himalayan orogeny, during Cambrian? Formed a series of Ordovician limestone strata? What? What are the topographic combinations such as zigzag, linear, circular, stepped cliff, Weng valley, deep barrier valley and suspended ditch? Yuntai? This landform constitutes a Taihang landscape with deep valleys and clear springs, which is of great significance to the study of neotectonic movement and rift evolution.

Yuntai Mountain Scenic Area has the Yunmengshan Formation of Mesoproterozoic Jixian System, which was formed 65.438+0.4 billion years ago to 300 million years ago. The outcrop system of Taiyuan Formation of Upper Carboniferous is complete; Archaean? There are also typical structural relics in the early Proterozoic basement, such as Archean gneiss complex structure in the basement, basement dome structure of early Proterozoic supracrustal rocks, overlying structure of caprock, ductile shear zone structure, ductile brittle deformation structure, brittle fracture structure, unilateral mountain structure, collapse structure and landslide structure in caprock, etc.
