The Danxia landform refers to various landscapes
found in southeast and southwest 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. 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.
The danxia landform is named after Mount Danxia, one of the
most famous examples of the danxia landform.
A very peculiar feature of danxia landscape is the
development of numerous caves of various sizes and shapes. The caves tend to be
shallow and isolated, unlike true karst terrain where caves tend to form deep,
interconnecting networks.
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 Wanfoshan (Hunan Province), Mount Danxia (Guangdong Province), Taining
and Guanzhishan (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.
So... just a quick something that caught my eye.
