Zhangye Danxia is known for the unusual colours of the rocks, which are smooth, sharp and several hundred meters tall. They are the result of deposits of sandstone and other minerals that occurred over 24 million years.
What type of rock is Danxia?
sandstones Danxia landform is formed from red-coloured sandstones and conglomerates of largely Cretaceous age. The landforms look very much like karst topography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called pseudo-karst landforms.
What type of landscape is Zhangye Danxia?
Zhangye Danxia National Geological Park is in the eastern foothills of the Qilian Mountains in Gansu Province, China.
What are the Rainbow Mountains made of?
sandstones The Rainbow Mountains are cretaceous sandstones and siltstones that were deposited in China before the Himalayan Mountains were formed. The sand and silt was deposited with iron and trace minerals that provided it with the key ingredient to form the colors we see today.
How did Zhangye Danxia China form?
Zhangye s Danxia was formed by the erosion of red sandstone, forming isolated peaks and steep stratified outcrops. Its special geological structure, combined with long-term desert conditions , freeze-thaw peeling, and wind and water erosion gave rise to its present appearance.
Are the rainbow mountains in China real?
In China, theyre a reality. Part of the Zhangye Danxia Landform Geological Park in the Gansu province, these Technicolor peaks are a local tourist attraction known as the Rainbow Mountains. The mountains colors are naturally occurring.
