It is understood that the landform of "Hundred Miles Danxia" was formed in Himalayan orogeny 70 million years ago, with a total length of about 120 km, so it is called "Hundred Miles Danxia", also known as "Tianshan Geographical Scenery Corridor".
Hundred Li Danxia is the world's first primitive reproductive worship rock painting-Kangjia Shimenzi reproductive worship rock painting, which has a history of more than 3,000 years and belongs to the historical and cultural relics of Tianshan Serbs. Danxia landform is composed of green, purplish brown, vermilion, grayish green, grayish white, light yellow, brownish purple and other sandstones representing different Jurassic periods, forming a magnificent colorful mountain range.
Danxia landform
Danxia landform is a steep slope landform developed from red beds (not limited to red beds) dominated by terrestrial (including non-continental interlayers). This definition is accepted by most scholars and can also be expressed as "red bed landform characterized by steep cliffs".
Danxia landform is widely distributed in China. At present, Danxia landforms 1005 have been identified, which are distributed in 28 provinces (autonomous regions, municipalities directly under the central government and special administrative regions). Among them, Zhuhai and Qidonggou in southern Sichuan belong to young Danxia, Chishui Danxia in Guizhou belongs to young Danxia, Danxia Mountain in Guangdong belongs to mature Danxia, and Longhu Mountain in Jiangxi belongs to old Danxia. Danxia landform is located in tropical and subtropical regions.
Temperate humid-semi-humid, semi-arid-arid areas and alpine regions of Qinghai-Tibet Plateau are all distributed. The lowest altitude can be formed in the eastern coastal zone, and the highest altitude can appear on the Qinghai-Tibet Plateau above 4000 meters. But relatively concentrated in the southeast, southwest and northwest. Except China, it is distributed in Central Europe and Australia, among which China is the most widely distributed.
1928, Feng Jinglan and others named the red strata that constitute Danxia Mountain and the corresponding strata in northern Guangdong as "Danxia Layer". In 1938, Chen first put forward the concept of "Danxia Mountain Terrain". 1939, Chen officially used the taxonomic term "Danxia landform", and the concepts of Danxia stratum and Danxia landform (landform is landform) have been used ever since.
