Mount of Danxia is identified by multi-layered red sedimentary rocks of sandstone and conglomerate, and the area of was formed by the fluvial deposition through the basin 140-65 million years ago. The weather in Danxia area assist the oxidation reaction in rocks, and turned the color of them into red. Then these sediments were uplifted and condescend by water, and being accreted during the process. Finally, the area of Danxia was formed. Since the 6 million years ago, the basin of Danxia area has experienced several intermittent rises, which average increase of about 1 meter per 10,000 years. With the favor of water washing by the river, the mount of Danxia is cut into many layers, and formed the mount of Danxia nowadays.
