Binggou Danxia Landform
Binggou Danxia Landform is located in Sunan Yugur Autonomous County, on the junction of Qilian Mountain and Hexi corridor, with altitude between 1500 to 2550 meters above sea level. It extends 5-10 kilometers from north to south and 40 kilometers from east to west. Covering an area of more than 300 sq km. Binggou Danxia Landform is the best Mullion-like palace style Danxia Landform in China, which has the most peculiar form and complete development in China. In 2000 Binggou Danxia Landform was nominated by National Geographic Magazine as the World's top ten magical geographical wonders.
There in the Binggou Danxia Landform widespread with Danxia cliff, sandstone wall, stone stele, aiguilles and hills. Some of them look like buildings such as castle, pagoda while some look like human beings that full of life.
Danxia landforms cover several provinces in southeast China. Taining County, Fujian Province has very good examples of "young" danxia landforms wherein deep, narrow valleys have been formed. As the landform gets older, valleys widen and one gets isolated towers and ridges. The danxia landform is named after Mount Danxia, one of the most famous examples of the danxia landform. A very peculiar feature of danxia landscape is the development of numerous caves of various sizes and shapes. The caves tend to be shallow and isolated, unlike true karst terrain where caves tend to form deep, interconnecting networks. In 2010, several danxia landscapes in southern China, with a general name of "China Danxia", were inscribed as a World Heritage Site. The six inscribed danxia landform areas are: Mount Langshan and Mount Wanfo (Hunan Province),Mount Danxia (Guangdong Province), Taining and Mount Guanzhi (Fujian Province), Mount Longhu and Guifeng (Jiangxi Province), Fangyan, Mount Jianglang (Zhejiang Province), and Mount Chishui (Guizhou Province). The total core area of 6 regions above is 73945 ha, and the total buffer area is 65446 ha. Other notable danxia areas, such asZhangye Danxia National Geological Park, are not included in the World Heritage Site.
Around 80 million years ago cretaceous red sandstone and conglomerate were laid down through sedimentation of lakes and streams. After another 15 million years, tectonic plate movement exposed many faults. About 23 million ago, movement of the Himalayan range, disturbed the land around Guandong, China creating much uplift and completely changing the topography of the area. Over millions of years the steep cliffs that can be seen today were formed through weathering and erosion, exposed by faults. This geology can be seen at Danxiashan Geopark in China, where there is about 290 square kilometers of streams, forest and towering danxian rock formations.
