Colorful Chinese Mountains: Zhangye Danxia

Colorful Chinese Mountains - rock formations, consisting of multiple layers of reddish sandstone. They are located in the eponymous National Geopark in China's northwestern Gansu Province. This place is a unique example of petrographic geomorphology, is found only in China. The composition of colored rocks Zhangye Danks enters the red sandstone and conglomerates (sedimentary rock), formed during the Cretaceous period.


Today, the picturesque district of colored rocks Zhangye Danks popular with travelers from all corners of the world who come here to enjoy the scenic walks and boating through the area, which are also home to a number of temples.

The whole world has learned about this natural attraction Zhangye town after the World Heritage Committee at its 34th meeting decided to make Zhangye colored cliffs on the World Heritage List by UNESCO. The meeting took place on August 1, 2010 in the capital of Brazil - Brasilia. This event prompted the local authorities to build boardwalks and roads that were supposed to simplify the access of tourists to the colored rocks.


The history of rock formations Zhangye Danks
Numerous studies have shown that about 100 million. Moreover years ago this place was a pool of impressive dimensions. Water flows slowly deposited silt in it. Under the influence of the global pool of high water temperatures have dried up, and the residue was started oxidized, acquiring the color of rust.


Approximately 70 million. Years ago the red layer was formed in the basin, which has a thickness of 3700 meters and it is called the Cretaceous geological bed. The top covered with a solid layer of rock about 1,300 meters thick, from which the mountain peaks Danks started to form over time.

Over the past 30 million. Years landscape pool several times changed its appearance due to the seismic process, during which formed the mountains. At this time, the rapid streams carved in sedimentary rock slopes.

Through experimentation we found out that the formation of the mountains in this area is still in progress. Every 10,000 years, the slopes are above 0.87 meters, and the height of today, they have gained over the past 500,000 years.
