Rainbow Mountain! It is astonishing to hear! Not a fairytale, Zhangye Danxia Landform Geological Park in the Rainbow Mountains of China is a geological wonder.

Rainbow Mountains are a geological wonder in the world. This famous Chinese mountain is known for the rainbow painted on the rolling hills made by paranormal colors.

This is probably the first example where geology is forced to take our attention and questions come in. What is the color of Rainbow Mountains colored? Here I will talk about diagenetic and mineralogical processes, through which these hills become red, green, yellow and blue.
Zhangye Danxia National Park is located in the Gansu province of China, in the northwestern part of 200 square miles. In 2009 it was named UNESCO World Heritage Site and became a destination for many Chinese and international tourists.

Think, how is the Rainbow Mountains form?
The Rainbow Mountains are composed of crystals of sandstone and siltstones, which are also preceded by the formation of the Himalaya Mountains. The color we see today is made to insert the main components of sand, poly iron and trace minerals. About 55 million years ago, a layered horizontal and flat stratification was interrupted due to the conflict between the Indian plate and the Eurasian plate. If two cars are taken out of a rack, then the cars will be involved in the same rivalry between themselves and their flat parts will be broken, in the same process, the Reno Mountains flat sandstone. This process took place on the mountain by the part of sedimentary rock that was hidden under the ground. Weathering and erosion exposes the surface layer of the continental siliciclastic rocks to the underlying structure of various metallurgy and chemistry.
These rainbow ranges make attractive variations of colors. He got an idea of ​​how the Rainbow Mountains formed. Now let's look at how we can see this color. The accelerated underground sandstone comes through the grain and the grain becomes in the mineral traction medium. This process allows for the paranormal color of the globe!

This mountain's sandstone primary color is dark red. In red sandstone, there is an iron oxide coating, which is also known as Value Added Oracle (Fe2O3).

Mixed iron oxide mixed with weathering, water and oxygen makes the iron iron, which is significant for its dark red color. The Rainbow Mountains are mainly identified due to this iron oxide for the formation of its sandstone Danxia.

Often, iron oxide is often referred to as a dark red pigment, but oxide is formed in different colors. For example, the limbite or goethite sandstone will be re-produced brown or yellow, even magnetite can rebuild black sandstone if there is iron sulfide. Again, a metallic yellow color is made by sulfur. Meanwhile, green color is due to chlorite or iron silicate clay. These are just some examples of how sandstone diagenesis can be changed in color! Due to many other elements, there are many color production!
Fortunately to see this same process, you do not have to travel to China in the northwest. Go to adventures and try to show all the rocks that have a red color! Maybe you can mark an iron oxide stained sandstone! But let me know!
