China Danxia

Introduction

China Danxia, or Danxia landform of China, is the general name of the unique type of landscapes, Danxia landform, formed from red sandstone and characterised by steep cliffs, which are caused by endogenous forces (including uplift) and exogenous forces (including weathering and erosion). In August 2010, China Danxia was inscribed onto the UNESCO World Heritage List. Danxia landforms cover several provinces in southeast China. Taining County, Fujian Province, has very good examples of "young" danxia landforms wherein deep, narrow valleys have been formed. As the landform gets older, valleys widen and one gets isolated towers and ridges.

In 2010, several danxia landscapes in southern China, with a general name of "China Danxia", were inscribed as a World Heritage Site. The six inscribed danxia landform areas are: Mount Langshan and Mount Wanfo (Hunan Province), Mount Danxia (Guangdong Province), Taining and Mount Guanzhi (Fujian Province), Mount Longhu and Guifeng (Jiangxi Province), Fangyan, Mount Jianglang (Zhejiang Province), and Mount Chishui (Guizhou Province). The total core area of 6 regions above is 73945 ha, and the total buffer area is 65446 ha. Other notable danxia areas, such as Zhangye Danxia National Geological Park, are not included in the World Heritage Site.

Geology

The Danxia landform 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-coloured 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.
