DescriptionRainbowmtnspt1 oli 2020261 lrg.jpeg	The first image shows Zhangye National Geological Park, which spans 322 square kilometers (124 square miles) of the prefecture of Zhangye. The widespread rusty color is sandstone, which was colored deep red during its formation by iron oxide. Other oxides imparted browns, yellows, and even greens to the various layers of rocks. It is a geologic marvel that the park’s colorful layers—deposited tens of millions of years ago during the Cretaceous Period—are visible at all. Folding and faulting processes have since lifted and deformed the rock, exposing layers that would otherwise have remained out of sight. Much of this crumpling and disruption of the stratigraphy is thought to have resulted from the “recent” collision of the Indian and Eurasian plates about 50 million years ago during the Cenozoic Era. Recent research suggests, however, that some of the deformation is even older.
