Karst Cave, China. Photograph by Raymond Gehman. Looking like the set of a science fiction movie, China's Reed Flute Cave is bathed in purple-blue light.

Corrasional cave or erosional cave. Corrasional or erosional caves are those that form entirely by erosion by flowing streams carrying rocks and other sediments. These can form in any type of rock, including hard rocks such as granite. Generally there must be some zone of weakness to guide the water, such as a fault or joint. A subtype of the erosional cave is the wind or aeolian cave, carved by wind-born sediments.
