Danxia rock formations are located in Gansu province, in Zhangye prefecture.
The Danxia landform (丹霞地貌; pinyin: dānxiá dìmào) refers to various landscapes found in southeast, southwest, and northwest China that “consist of a red bed characterized by steep cliffs”. It is a unique type of petrographic geomorphology found in China. Danxia landform is formed from red-colored sandstones and conglomerates of largely Cretaceous age. The landforms look very much like karst topography that forms in areas underlain by limestones, but since the rocks that form danxia are sandstones and conglomerates, they have been called “pseudo-karst” landforms.
