Monoklinische Kalksteine - Monoclinic Limestones

Monoclinic Limestones, Danxia Geopark 2018

On the fourth platform, you can marvel the spectacular Rainbow Mountains as well as a completely different landscape, which clearly differs from all previous ones. The Monoclinic Limestones are unique in the Geopark. Formations like the Rainbow Mountains can also be found in the Color Hills or the Flying Clouds, but that does not scale them down because this landscape is simply too charming to get tired of. However, the red-and-green landscape with the gray spikes on the horizon and the view of Zhangye in the distance offers an unexpected variety.

The Danxi Geopark at Zhangye is one of the most beautiful and popular national parks with Danxia landscapes in China due to its very colorful and quirky rock formations. Danxia means ‘red clouds’ in Chinese. The rocky landscape, which is known nationally for its special variety of colors, was given the status of a national park in November 2011. The 510 square kilometer area is located on the northern foothills of the Qilian Mountains.

About 540 million years ago, the area was once part of the ocean. Due to the collision of the tectonic plate, the land folded and formed mountains and rose above the sea level. Red sandstone was deposited when rivers formed in the area. As the ground sank into a basin, mudstone deposited on the red sandstone. At different times, different sedimentary rocks were formed containing different amounts of iron salt in the mud and rock. That’s why the layers have different colors. Each shift took thousands of years to form. The movement of the Himalayas raised the area and rivers formed. The river erosion formed canyons and the early landscape of Danxia was created. After further geological periods, river erosion and wind erosion formed the colorful layers you see today.
