Clastic Rock Landscape
A clastic rock landscape is a type of landscape which main components are sandstone, conglomerate, siltstone and clayey siltstone. Compacted sandstone and conglomerate are hard and resistant to wind erosion. Due to these characteristics, they form outstanding features, such as cliffs, walls, pillars, mesas, natural bridges, arches and potholes. Soft siltstone with a loose structure forms a badland landscape with small knolls and depressions. Based on the geographic location, formation age, formation dynamics and landforms, clastic rock landscapes can be categorised into Zhangshiyan type, Urho type, Danxia type, Yeliu type, Yuanmou type, Luliang type and Yardang type. Clastic rock landscapes are an important tourism resource.
