These look more like a sketch of a fantasy landscape but in reality exist just a hop and skip away in Guangdong, China. The Zhangye Danxia landform shows geology at its finest: breathtaking rock pigments and a range of topological features.
The Danxia landforms are unique to China, and are comprised of sandstones. The colours are said to be derived from organic sediment as well as minerals present in/cementing the sandstone itself. Of course tectonics were also at work, producing the dip of the layers and folding of the rock.
Needless to say this is an interesting site for a number of reasons. There does not seem to be too much literature (in English at least) on the geology of the site, so the exact nature of the tectonics and folding, as well as a thorough explanation of the colour of the formations are unknown to me. I may not have found structural geology to be my strong point, but does this site ever make me curious about the forces at work! I even opted to check Google Earth to try my hand at remote sensing for the region, but the topographical and satellite imagery detail are a bit mediocre, no surprise.
This is definitely one of the highest on my bucket list, though I expect that if I were to go to the site as a tourist I would be sorely disappointed at my inability to get my hands dirty and truly investigate the geology of the area.
