Huichang basin is located in the west piedmont of the southern Wuyi mountain and in which the Late cretaceous red beds develop typical Danxia landforms. The landscape types include shifeng

wallflowers

column

thin strip of sky

caves and shape stone

and they mainly distributed in the basin edge region

some others distributed in the central basin. Danxia landform develop in the thick bedded pebbled sandstone of Maodian formation

Zhoutian formation and Hekou formation

including Zhoutian formation is the main landscape genesis layer. The lithology of late cretaceous red beds is mainly for purple conglomerate

fine conglomerate

sandstone

siltstone and mudstone. Due to the influences of landscape genesis elements such as boundary fault

lithology

tectonic activity and fluviation

different Danxia landform types develop in different location of the basin.
